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

This example scrapes the reviews shown on the home page of metalsucks.net.
package main import ( "fmt" "log" "net/http" "github.com/PuerkitoBio/goquery" ) func main() { // Request the HTML page. res, err := http.Get("http://metalsucks.net") if err != nil { log.Fatal(err) } defer res.Body.Close() if res.StatusCode != 200 { log.Fatalf("status code error: %d %s", res.StatusCode, res.Status) } // Load the HTML document doc, err := goquery.NewDocumentFromReader(res.Body) if err != nil { log.Fatal(err) } // Find the review items doc.Find(".sidebar-reviews article .content-block").Each(func(i int, s *goquery.Selection) { // For each item found, get the band and title band := s.Find("a").Text() title := s.Find("i").Text() fmt.Printf("Review %d: %s - %s\n", i, band, title) }) // To see the output of the Example while running the test suite (go test), simply // remove the leading "x" before Output on the next line. This will cause the // example to fail (all the "real" tests should pass). // xOutput: voluntarily fail the Example output. }

Functions ¶
func NodeName ¶ added in v1.0.0
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 ¶ added in v1.0.0
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 ¶
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 ¶ added in v1.0.0
CloneDocument creates a deep-clone of a document.
func NewDocument
deprecated
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.
Deprecated: Use the net/http standard library package to make the request and validate the response before calling goquery.NewDocumentFromReader with the response's body.
func NewDocumentFromNode ¶
NewDocumentFromNode is a Document constructor that takes a root html Node as argument.
func NewDocumentFromReader ¶ added in v0.3.2
NewDocumentFromReader returns a Document from an io.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, the provided reader is never closed by this call. It is the responsibility of the caller to close it if required.
Example (File) ¶
This example shows how to use NewDocumentFromReader from a file.
package main import ( "log" "os" "github.com/PuerkitoBio/goquery" ) func main() { // create from a file f, err := os.Open("some/file.html") if err != nil { log.Fatal(err) } defer f.Close() doc, err := goquery.NewDocumentFromReader(f) if err != nil { log.Fatal(err) } // use the goquery document... _ = doc.Find("h1") }
Output:
Example (String) ¶
This example shows how to use NewDocumentFromReader from a string.
package main import ( "fmt" "log" "strings" "github.com/PuerkitoBio/goquery" ) func main() { // create from a string data := ` <html> <head> <title>My document</title> </head> <body> <h1>Header</h1> </body> </html>` doc, err := goquery.NewDocumentFromReader(strings.NewReader(data)) if err != nil { log.Fatal(err) } header := doc.Find("h1").Text() fmt.Println(header) }
Output: Header
func NewDocumentFromResponse
deprecated
added in
v0.3.1
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.
Deprecated: Use goquery.NewDocumentFromReader with the response's body.
type Matcher ¶ added in v1.0.0
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 ¶
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 ¶
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) AddBack ¶ added in v1.2.0
AddBack adds the previous set of elements on the stack to the current set. It returns a new Selection object containing the current Selection combined with the previous one.
func (*Selection) AddBackFiltered ¶ added in v1.2.0
AddBackFiltered reduces the previous set of elements on the stack to those that match the selector string, and adds them to the current set. It returns a new Selection object containing the current Selection combined with the filtered previous one
func (*Selection) AddBackMatcher ¶ added in v1.2.0
AddBackMatcher reduces the previous set of elements on the stack to those that match the mateher, and adds them to the curernt set. It returns a new Selection object containing the current Selection combined with the filtered previous one
func (*Selection) AddClass ¶ added in v1.0.0
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 ¶ added in v1.0.0

func (*Selection) After ¶ added in v1.0.0
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 ¶ added in v1.0.0
AfterHtml parses the html and inserts it after the set of matched elements.
This follows the same rules as Selection.Append.
func (*Selection) AfterMatcher ¶ added in v1.0.0
AfterMatcher applies the matcher from the root document and inserts the matched elements after the elements in the set of matched elements.

This follows the same rules as Selection.Append.
func (*Selection) AfterSelection ¶ added in v1.0.0
AfterSelection inserts the elements in the selection after each element in the set of matched elements.
This follows the same rules as Selection.Append.
func (*Selection) AndSelf ¶
AndSelf adds the previous set of elements on the stack to the current set. It returns a new Selection object containing the current Selection combined with the previous one. Deprecated: This function has been deprecated and is now an alias for AddBack().
func (*Selection) Append ¶ added in v1.0.0
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 ¶ added in v1.0.0
AppendHtml parses the html and appends it to the set of matched elements.
func (*Selection) AppendMatcher ¶ added in v1.0.0
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.

func (*Selection) AttrOr ¶ added in v1.0.0
AttrOr works like Attr but returns default value if attribute is not present.
func (*Selection) Before ¶ added in v1.0.0
Before inserts the matched elements before each element in the set of matched elements.
This follows the same rules as Selection.Append.

func (*Selection) ClosestSelection ¶ added in v0.2.0
ClosestSelection gets the first element that matches one of the nodes in the Selection by testing the element itself and traversing up through its ancestors in the DOM tree.
func (*Selection) Contains ¶
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 ¶
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 ¶
ContentsFiltered gets the children of each element in the Selection, filtered by the specified selector. It returns a new Selection object containing these elements. Since selectors only act on Element nodes, this function is an alias to ChildrenFiltered unless the selector is empty, in which case it is an alias to Contents.
func (*Selection) ContentsMatcher ¶ added in v1.0.0
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) Each ¶
Each iterates over a Selection object, executing a function for each matched element. It returns the current Selection object. The function f is called for each element in the selection with the index of the element in that selection starting at 0, and a *Selection that contains only that element.
func (*Selection) EachWithBreak ¶ added in v0.3.0
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 ¶ added in v1.0.0
Empty removes all children nodes from the set of matched elements. It returns the children nodes in a new Selection.
func (*Selection) End ¶
End ends the most recent filtering operation in the current chain and returns the set of matched elements to its previous state.
func (*Selection) Eq ¶
Eq reduces the set of matched elements to the one at the specified index. If a negative index is given, it counts backwards starting at the end of the set. It returns a new Selection object, and an empty Selection object if the index is invalid.
func (*Selection) Filter ¶
Filter reduces the set of matched elements to those that match the selector string. It returns a new Selection object for this subset of matching elements.
func (*Selection) FilterFunction ¶
FilterFunction reduces the set of matched elements to those that pass the function's test. It returns a new Selection object for this subset of elements.

func (*Selection) FindSelection ¶
FindSelection gets the descendants of each element in the current Selection, filtered by a Selection. It returns a new Selection object containing these matched elements.
func (*Selection) First ¶
First reduces the set of matched elements to the first in the set. It returns a new Selection object, and an empty Selection object if the the selection is empty.
func (*Selection) Get ¶
