>假设我有这个HTML页面。我想使用 Go 和 goquery 解析它:
<html>
<head><!--Page header stuff--></head>
<body>
<h1 class="h1-class">Heading 1</h1>
<div class="div-class">Stuff1</div>
<div class="div-class">Stuff2</div>
<h1 class="h1-class">Heading 2</h1>
<div class="div-class">Stuff3</div>
<div class="div-class">Stuff4</div>
</body>
</html>
碰巧的是,我只想在标题 2 之前获得这些 DIV,然后跳过其余部分。此代码非常适合获取所有 DIV:
doc := GetGoQueryDocument(url) //Defined elsewhere
doc.Find("div.div-class").Each(func(_ int, theDiv *goquery.Selection){
//do stuff with each theDiv
//The problem is that it finds div.div-class elements below Heading 2.
//I want to skip those.
})
有没有办法告诉goquery跳过位于某个标签和类名下方的元素?感谢您的任何提示!
是的,实际上很简单:
doc.Find(".h1-class").First().NextUntil(".h1-class")
我建议你通读godoc:https://godoc.org/github.com/PuerkitoBio/goquery
它解释了您可以操作选择的所有不同方法。
