goquery - a little like that j-thing, only in Go build status GoDoc

goquery brings a syntax and a set of features similar to jQuery to the Go language. It is based on Go's net/html package and the CSS Selector library cascadia. Since the net/html parser returns nodes, and not a full-featured DOM tree, jQuery's stateful manipulation functions (like height(), css(), detach()) have been left off.

Also, because the net/html parser requires UTF-8 encoding, so does goquery: it is the caller's responsibility to ensure that the source document provides UTF-8 encoded HTML. See the wiki for various options to do this.

Syntax-wise, it is as close as possible to jQuery, with the same function names when possible, and that warm and fuzzy chainable interface. jQuery being the ultra-popular library that it is, I felt that writing a similar HTML-manipulating library was better to follow its API than to start anew (in the same spirit as Go's fmt package), even though some of its methods are less than intuitive (looking at you, index()...).

Installation

Please note that because of the net/html dependency, goquery requires Go1.1+.

$ go get github.com/PuerkitoBio/goquery

(optional) To run unit tests:

$ cd $GOPATH/src/github.com/PuerkitoBio/goquery
$ go test

(optional) To run benchmarks (warning: it runs for a few minutes):

$ cd $GOPATH/src/github.com/PuerkitoBio/goquery
$ go test -bench=".*"

Changelog

Note that goquery's API is now stable, and will not break.

  • 2016-08-28 (v1.0.1) : Optimize performance for large documents.
  • 2016-07-27 (v1.0.0) : Tag version 1.0.0.
  • 2016-06-15 : Invalid selector strings internally compile to a Matcher implementation that never matches any node (instead of a panic). So for example, doc.Find("~") returns an empty *Selection object.
  • 2016-02-02 : Add NodeName utility function similar to the DOM's nodeName property. It returns the tag name of the first element in a selection, and other relevant values of non-element nodes (see godoc for details). Add OuterHtml utility function similar to the DOM's outerHTML property (named OuterHtml in small caps for consistency with the existing Html method on the Selection).
  • 2015-04-20 : Add AttrOr helper method to return the attribute's value or a default value if absent. Thanks to piotrkowalczuk.
  • 2015-02-04 : Add more manipulation functions - Prepend* - thanks again to Andrew Stone.
  • 2014-11-28 : Add more manipulation functions - ReplaceWith*, Wrap* and Unwrap - thanks again to Andrew Stone.
  • 2014-11-07 : Add manipulation functions (thanks to Andrew Stone) and *Matcher functions, that receive compiled cascadia selectors instead of selector strings, thus avoiding potential panics thrown by goquery via cascadia.MustCompile calls. This results in better performance (selectors can be compiled once and reused) and more idiomatic error handling (you can handle cascadia's compilation errors, instead of recovering from panics, which had been bugging me for a long time). Note that the actual type expected is a Matcher interface, that cascadia.Selector implements. Other matcher implementations could be used.
  • 2014-11-06 : Change import paths of net/html to golang.org/x/net/html (see https://groups.google.com/forum/#!topic/golang-nuts/eD8dh3T9yyA). Make sure to update your code to use the new import path too when you call goquery with html.Nodes.
  • v0.3.2 : Add NewDocumentFromReader() (thanks jweir) which allows creating a goquery document from an io.Reader.
  • v0.3.1 : Add NewDocumentFromResponse() (thanks assassingj) which allows creating a goquery document from an http response.
  • v0.3.0 : Add EachWithBreak() which allows to break out of an Each() loop by returning false. This function was added instead of changing the existing Each() to avoid breaking compatibility.
  • v0.2.1 : Make go-getable, now that go.net/html is Go1.0-compatible (thanks to @matrixik for pointing this out).
  • v0.2.0 : Add support for negative indices in Slice(). BREAKING CHANGE Document.Root is removed, Document is now a Selection itself (a selection of one, the root element, just like Document.Root was before). Add jQuery's Closest() method.
  • v0.1.1 : Add benchmarks to use as baseline for refactorings, refactor Next...() and Prev...() methods to use the new html package's linked list features (Next/PrevSibling, FirstChild). Good performance boost (40+% in some cases).
  • v0.1.0 : Initial release.

API

goquery exposes two structs, Document and Selection, and the Matcher interface. Unlike jQuery, which is loaded as part of a DOM document, and thus acts on its containing document, goquery doesn't know which HTML document to act upon. So it needs to be told, and that's what the Document type is for. It holds the root document node as the initial Selection value to manipulate.

jQuery often has many variants for the same function (no argument, a selector string argument, a jQuery object argument, a DOM element argument, ...). Instead of exposing the same features in goquery as a single method with variadic empty interface arguments, statically-typed signatures are used following this naming convention:

  • When the jQuery equivalent can be called with no argument, it has the same name as jQuery for the no argument signature (e.g.: Prev()), and the version with a selector string argument is called XxxFiltered() (e.g.: PrevFiltered())
  • When the jQuery equivalent requires one argument, the same name as jQuery is used for the selector string version (e.g.: Is())
  • The signatures accepting a jQuery object as argument are defined in goquery as XxxSelection() and take a *Selection object as argument (e.g.: FilterSelection())
  • The signatures accepting a DOM element as argument in jQuery are defined in goquery as XxxNodes() and take a variadic argument of type *html.Node (e.g.: FilterNodes())
  • The signatures accepting a function as argument in jQuery are defined in goquery as XxxFunction() and take a function as argument (e.g.: FilterFunction())
  • The goquery methods that can be called with a selector string have a corresponding version that take a Matcher interface and are defined as XxxMatcher() (e.g.: IsMatcher())

Utility functions that are not in jQuery but are useful in Go are implemented as functions (that take a *Selection as parameter), to avoid a potential naming clash on the *Selection's methods (reserved for jQuery-equivalent behaviour).

The complete godoc reference documentation can be found here.

Please note that Cascadia's selectors do not necessarily match all supported selectors of jQuery (Sizzle). See the cascadia project for details. Invalid selector strings compile to a Matcher that fails to match any node. Behaviour of the various functions that take a selector string as argument follows from that fact, e.g. (where ~ is an invalid selector string):

  • Find("~") returns an empty selection because the selector string doesn't match anything.
  • Add("~") returns a new selection that holds the same nodes as the original selection, because it didn't add any node (selector string didn't match anything).
  • ParentsFiltered("~") returns an empty selection because the selector string doesn't match anything.
  • ParentsUntil("~") returns all parents of the selection because the selector string didn't match any element to stop before the top element.

Overview

Package goquery implements features similar to jQuery, including the chainable syntax, to manipulate and query an HTML document.

It brings a syntax and a set of features similar to jQuery to the Go language. It is based on Go's net/html package and the CSS Selector library cascadia. Since the net/html parser returns nodes, and not a full-featured DOM tree, jQuery's stateful manipulation functions (like height(), css(), detach()) have been left off.

Also, because the net/html parser requires UTF-8 encoding, so does goquery: it is the caller's responsibility to ensure that the source document provides UTF-8 encoded HTML. See the repository's wiki for various options on how to do this.

Syntax-wise, it is as close as possible to jQuery, with the same method names when possible, and that warm and fuzzy chainable interface. jQuery being the ultra-popular library that it is, writing a similar HTML-manipulating library was better to follow its API than to start anew (in the same spirit as Go's fmt package), even though some of its methods are less than intuitive (looking at you, index()...).

It is hosted on GitHub, along with additional documentation in the README.md file: https://github.com/puerkitobio/goquery

Functions

func NodeName 

func NodeName(s *Selection) string

NodeName returns the node name of the first element in the selection. It tries to behave in a similar way as the DOM's nodeName property (https://developer.mozilla.org/en-US/docs/Web/API/Node/nodeName).

Go's net/html package defines the following node types, listed with the corresponding returned value from this function: 

ErrorNode : #error
TextNode : #text
DocumentNode : #document
ElementNode : the element's tag name
CommentNode : #comment
DoctypeNode : the name of the document type

func OuterHtml 

func OuterHtml(s *Selection) (string, error)

OuterHtml returns the outer HTML rendering of the first item in the selection - that is, the HTML including the first element's tag and attributes.

Unlike InnerHtml, this is a function and not a method on the Selection, because this is not a jQuery method (in javascript-land, this is a property provided by the DOM).

Types

type Document 

type Document struct {
	*Selection
	Url *url.URL
	// contains filtered or unexported fields
}

Document represents an HTML document to be manipulated. Unlike jQuery, which is loaded as part of a DOM document, and thus acts upon its containing document, GoQuery doesn't know which HTML document to act upon. So it needs to be told, and that's what the Document class is for. It holds the root document node to manipulate, and can make selections on this document.

func CloneDocument 

func CloneDocument(doc *Document) *Document

CloneDocument creates a deep-clone of a document.

func NewDocument 

func NewDocument(url string) (*Document, error)

NewDocument is a Document constructor that takes a string URL as argument. It loads the specified document, parses it, and stores the root Document node, ready to be manipulated.

func NewDocumentFromNode 

func NewDocumentFromNode(root *html.Node) *Document

NewDocumentFromNode is a Document constructor that takes a root html Node as argument.

func NewDocumentFromReader 

func NewDocumentFromReader(r io.Reader) (*Document, error)

NewDocumentFromReader returns a Document from a generic reader. It returns an error as second value if the reader's data cannot be parsed as html. It does *not* check if the reader is also an io.Closer, so the provided reader is never closed by this call, it is the responsibility of the caller to close it if required.

func NewDocumentFromResponse 

func NewDocumentFromResponse(res *http.Response) (*Document, error)

NewDocumentFromResponse is another Document constructor that takes an http response as argument. It loads the specified response's document, parses it, and stores the root Document node, ready to be manipulated. The response's body is closed on return.

type Matcher 

type Matcher interface {
	Match(*html.Node) bool
	MatchAll(*html.Node) []*html.Node
	Filter([]*html.Node) []*html.Node
}

Matcher is an interface that defines the methods to match HTML nodes against a compiled selector string. Cascadia's Selector implements this interface.

type Selection 

type Selection struct {
	Nodes []*html.Node
	// contains filtered or unexported fields
}

Selection represents a collection of nodes matching some criteria. The initial Selection can be created by using Document.Find, and then manipulated using the jQuery-like chainable syntax and methods.

func (*Selection) Add 

func (s *Selection) Add(selector string) *Selection

Add adds the selector string's matching nodes to those in the current selection and returns a new Selection object. The selector string is run in the context of the document of the current Selection object.

func (*Selection) AddClass 

func (s *Selection) AddClass(class ...string) *Selection

AddClass adds the given class(es) to each element in the set of matched elements. Multiple class names can be specified, separated by a space or via multiple arguments.

func (*Selection) AddMatcher 

func (s *Selection) AddMatcher(m Matcher) *Selection

AddMatcher adds the matcher's matching nodes to those in the current selection and returns a new Selection object. The matcher is run in the context of the document of the current Selection object.

func (*Selection) AddNodes 

func (s *Selection) AddNodes(nodes ...*html.Node) *Selection

AddNodes adds the specified nodes to those in the current selection and returns a new Selection object.

func (*Selection) AddSelection 

func (s *Selection) AddSelection(sel *Selection) *Selection

AddSelection adds the specified Selection object's nodes to those in the current selection and returns a new Selection object.

func (*Selection) After 

func (s *Selection) After(selector string) *Selection

After applies the selector from the root document and inserts the matched elements after the elements in the set of matched elements.

If one of the matched elements in the selection is not currently in the document, it's impossible to insert nodes after it, so it will be ignored.

This follows the same rules as Selection.Append.

func (*Selection) AfterHtml 

func (s *Selection) AfterHtml(html string) *Selection

AfterHtml parses the html and inserts it after the set of matched elements.

This follows the same rules as Selection.Append.

AfterMatcher applies the matcher from the root document and inserts the matched elements after the elements in the set of matched elements.

If one of the matched elements in the selection is not currently in the document, it's impossible to insert nodes after it, so it will be ignored.

This follows the same rules as Selection.Append.

func (*Selection) AfterNodes 

func (s *Selection) AfterNodes(ns ...*html.Node) *Selection

AfterNodes inserts the nodes after each element in the set of matched elements.

This follows the same rules as Selection.Append.

func (*Selection) Append 

func (s *Selection) Append(selector string) *Selection

Append appends the elements specified by the selector to the end of each element in the set of matched elements, following those rules:

1) The selector is applied to the root document.

2) Elements that are part of the document will be moved to the new location.

3) If there are multiple locations to append to, cloned nodes will be appended to all target locations except the last one, which will be moved as noted in (2).

func (*Selection) AppendHtml 

func (s *Selection) AppendHtml(html string) *Selection

AppendHtml parses the html and appends it to the set of matched elements.

func (*Selection) AppendMatcher 

func (s *Selection) AppendMatcher(m Matcher) *Selection

AppendMatcher appends the elements specified by the matcher to the end of each element in the set of matched elements.

This follows the same rules as Selection.Append.

This follows the same rules as Selection.Append.

func (*Selection) Attr 

func (s *Selection) Attr(attrName string) (val string, exists bool)

Attr gets the specified attribute's value for the first element in the Selection. To get the value for each element individually, use a looping construct such as Each or Map method.

func (*Selection) AttrOr 

func (s *Selection) AttrOr(attrName, defaultValue string) string

AttrOr works like Attr but returns default value if attribute is not present.

func (*Selection) Before 

func (s *Selection) Before(selector string) *Selection

Before inserts the matched elements before each element in the set of matched elements.

This follows the same rules as Selection.Append.

func (*Selection) BeforeHtml 

func (s *Selection) BeforeHtml(html string) *Selection

BeforeHtml parses the html and inserts it before the set of matched elements.

This follows the same rules as Selection.Append.

func (*Selection) BeforeMatcher 

func (s *Selection) BeforeMatcher(m Matcher) *Selection

BeforeMatcher inserts the matched elements before each element in the set of matched elements.

This follows the same rules as Selection.Append.

func (*Selection) BeforeNodes 

func (s *Selection) BeforeNodes(ns ...*html.Node) *Selection

func (*Selection) Contains 

func (s *Selection) Contains(n *html.Node) bool

Contains returns true if the specified Node is within, at any depth, one of the nodes in the Selection object. It is NOT inclusive, to behave like jQuery's implementation, and unlike Javascript's .contains, so if the contained node is itself in the selection, it returns false.

func (*Selection) Contents 

func (s *Selection) Contents() *Selection

Contents gets the children of each element in the Selection, including text and comment nodes. It returns a new Selection object containing these elements.

func (*Selection) ContentsFiltered 

func (s *Selection) ContentsFiltered(selector string) *Selection

ContentsFiltered gets the children of each element in the Selection, filtered by the specified selector. It returns a new Selection object containing these elements.

func (*Selection) ContentsMatcher 

func (s *Selection) ContentsMatcher(m Matcher) *Selection

ContentsMatcher gets the children of each element in the Selection, filtered by the specified matcher. It returns a new Selection object containing these elements. Since matchers only act on Element nodes, this function is an alias to ChildrenMatcher.

func (*Selection) EachWithBreak 

func (s *Selection) EachWithBreak(f func(int, *Selection) bool) *Selection

EachWithBreak iterates over a Selection object, executing a function for each matched element. It is identical to Each except that it is possible to break out of the loop by returning false in the callback function. It returns the current Selection object.

func (*Selection) Empty 

func (s *Selection) Empty() *Selection

Empty removes all children nodes from the set of matched elements. It returns the children nodes in a new Selection.
