Jsoup-取得父母

Question

I have some HTML and I am trying to get a link, and I know a few qualities the link I want will have so I can find it easily, but not I also want to get the <h2 calss='locs'> tag above the link I have. 我有一些HTML，并且正在尝试获取链接，并且我知道我想要的链接具有一些品质，因此我可以轻松找到它，但我也不想在上方获得<h2 calss='locs'>标签我有链接。 So the html might look like this 因此，html可能看起来像这样

<html>
    <body>
        <h2 class = 'locs'>text</h2>
        <p>
           <a link and stuff...>
        </p>
        <h2 class = 'locs'>foo</h2>
        <p>
           <a another link and stuff...>
        </p>
    </body>
</html>

But the <h2> isn't always just the first parent of the <a> so is there a way to search for the that comes before the link? 但是<h2>并不总是<a>的第一个父项，因此有没有办法搜索链接之前的？

Thanks for the help 谢谢您的帮助

I am not totally sure what you are asking, but this is what I assume: You want the first a Element after a h2 Element of class locs . 我不确定您要问的是什么，但这是我的假设：您想要在class locs的h2 Element之后的第a Element。

To do this, you can#t use the parent() method, since the a elements parents seem to be p elements which are in turn siblings (not children) of the h2.locs Elements. 为此，您不能使用parent()方法，因为a元素的父元素似乎是p元素，而这些元素又是h2.locs元素的h2.locs元素（而不是子元素）。 Here is what i would do: 这是我会做的：

Elements as = doc.select("h2.locs + p>a");

Explanation: 说明：

h2.locs looks for h2 elments with class locs h2.locs使用类locs查找h2 h2.locs
A + B looks for B which must be direct sibling to the previous A. A + B查找必须与先前A直接同级的B。
p>a looks for a elements which are children of p p>a寻找a它们的子元素p
