goqueryGo 的 HTML/XML 解析库
goquery是一个使用go语言写成的HTML解析库，可以让你像jQuery那样的方式来操作DOM文档。下面是示例：
func ExampleScrape_MetalReview() {
// Load the HTML document (in real use, the type would be *goquery.Document)
var doc *Document
var e error
if doc, e = NewDocument("http://metalreview.com"); e != nil {
panic(e.Error())
}
// Find the review items (the type of the Selection would be *goquery.Selection)
doc.Find(".slider-row:nth-child(1) .slider-item").Each(func(i int, s *Selection) {
var band, title string
var score float64
// For each item found, get the band, title and score, and print it
band = s.Find("strong").Text()
title = s.Find("em").Text()
if score, e = strconv.ParseFloat(s.Find(".score").Text(), 64); e != nil {
// Not a valid float, ignore score
fmt.Printf("Review %d: %s - %s.\n", i, band, title)
} else {
// Print all, including score
fmt.Printf("Review %d: %s - %s (%2.1f).\n", i, band, title, score)
}
