CSS selectors in Go
This package implements a CSS selector compiler for Go's HTML parsing package golang.org/x/net/html.
package main
import (
"fmt"
"os"
"strings"
"github.com/ericchiang/css"
"golang.org/x/net/html"
)
var data = `
<p>
<h2 id="foo">a header</h2>
<h2 id="bar">another header</h2>
</p>`
func main() {
sel, err := css.Parse("h2#foo")
if err != nil {
panic(err)
}
node, err := html.Parse(strings.NewReader(data))
if err != nil {
panic(err)
}
for _, ele := range sel.Select(node) {
html.Render(os.Stdout, ele)
}
fmt.Println()
}
$ go run example/css.go
<h2 id="foo">a header</h2>
