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

build status GoDoc Sourcegraph Badge

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


package), even though some of its methods are less than intuitive (looking at you, index()...).

Table of Contents


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

$ go get

(optional) To run unit tests:

$ cd $GOPATH/src/ $ go test

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

$ cd $GOPATH/src/ $ go test -bench=".\*"


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

  • 2014-11-07 : Add manipulation functions (thanks to Andrew Stone) and
    functions, that receive compiled cascadia selectors instead of selector strings, thus avoiding potential panics thrown by goquery via
    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
    interface, that
    implements. Other matcher implementations could be used.

  • v0.3.0 : Add
    which allows to break out of an

  • v0.2.1 : Make go-getable, now that is Go1.0-compatible (thanks to @matrixik for pointing this out).
  • v0.2.0 : Add support for negative indices in Slice(). BREAKING CHANGE
    is removed,

    itself (a selection of one, the root element, just like
    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.


goquery exposes two structs,




, and the


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


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.:
    ), and the version with a selector string argument is called
  • When the jQuery equivalent requires one argument, the same name as jQuery is used for the selector string version (e.g.:
  • The signatures accepting a jQuery object as argument are defined in goquery as
    and take a
    object as argument (e.g.:
  • The signatures accepting a DOM element as argument in jQuery are defined in goquery as
    and take a variadic argument of type
  • The signatures accepting a function as argument in jQuery are defined in goquery as
    and take a function as argument (e.g.:
  • The goquery methods that can be called with a selector string have a corresponding version that take a
    interface and are defined as

Utility functions that are not in jQuery but are useful in Go are implemented as functions (that take a


as parameter), to avoid a potential naming clash on the


'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


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):


returns an empty selection because the selector string doesn't match anything.


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).


returns an empty selection because the selector string doesn't match anything.


returns all parents of the selection because the selector string didn't match any element to stop before the top element.


See some tips and tricks in the wiki.

Adapted from example_test.go:

package main import ( "fmt" "log" "net/http" "" ) func ExampleScrape() { // Request the HTML page. res, err := http.Get("") 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) }) } func main() { ExampleScrape() }

  • Use it, star it, build something with it, spread the word!
    • If you do build something open-source or otherwise publicly-visible, let me know so I can add it to the Related Projects section!
  • Raise issues to improve the project (note: doc typos and clarifications are issues too!)
    • Please search existing issues before opening a new one - it may have already been adressed.
  • Pull requests: please discuss new code in an issue first, unless the fix is really trivial.
    • Make sure new code is tested.
    • Be mindful of existing code - PRs that break existing code have a high probability of being declined, unless it fixes a serious issue.
