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

-GoQuery brings a syntax and a set of features similar to [jQuery][] to the [Go language][go]. It is based on the [experimental html package][exphtml] and the CSS Selector library [cascadia][]. Since the experimental html parser returns tokens (nodes), and not a full-featured DOM object, jQuery's manipulation and modification functions have been left off (no point in modifying data in the parsed tree of the HTML, it has no effect).

Since the experimental html parser returns tokens (nodes), and not a full-featured DOM object, jQuery's manipulation and modification functions have been left off (no point in modifying data in the parsed tree of the HTML, it has no effect).

 Supported functions are query-oriented features (`hasClass()`, `attr()` and the likes), as well as traversing functions that make sense given what we have to work with. This makes GoQuery a great library for scraping web pages.

 ## Installation

-Since this library (and cascadia) depends on the experimental branch, this package must be installed first. Both GoQuery and Cascadia expect to find the experimental library with the `"exp/html"` import statement. To install it at this location, there's [this guide][wikiexp], but since late December 2012, Go tip has evolved and `"exp/html"` won't build with Go1.0.3. So the last valid revision that will build with Go1 is `d9ff34d481bc`. Just replace the second step in [the guide][wikiexp] with this command:
+    $ go get github.com/PuerkitoBio/goquery

-    hg clone -r d9ff34d481bc https://code.google.com/p/go go-exp
+(optional) To run unit tests:
+    
+    $ cd $GOPATH/src/github.com/PuerkitoBio/goquery
+    $ go test

-The rest of the guide can be followed as-is (note that you can build just the `exp/html` package, you don't have to build `exp/...`).
+(optional) To run benchmarks:

-Once this is done, install GoQuery:
-
-`go get github.com/PuerkitoBio/goquery`
-
-To run unit tests, run this command in goquery's source directory (`$GOPATH/src/github.com/PuerkitoBio/goquery`):
-
-`go test`
-
-To run benchmarks, run this command in goquery's source directory:
-
-`go test -bench=".*"`
+    $ cd $GOPATH/src/github.com/PuerkitoBio/goquery
+    $ go test -bench=".*"

 ## Changelog

+*    **v0.2.1** : Make go-getable, now that [go.net/html is Go1.0-compatible][gonet] (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.
