我有以下结构:
<html>
<head>
<title>Index of /</title>
</head>
<body>
<h1>Index of /</h1>
<pre>
<img src="/icons/blank.gif" alt="Icon "> <a href="?C=N;O=D">Name</a> <a
href="?C=M;O=A">Last modified</a> <a href="?C=S;O=A">Size</a> <a
href="?C=D;O=A">Description</a>
<hr>

....
</pre>
所以现在我正在尝试获取 <a href=... 的信息但仅适用于那些遵循 <img src=".." alt="[DIR]">... 的人
所以我创建了一个如下所示的 XPath:
tester.getElementsByXPath("/html/body/pre/*[self::img[@alt='[DIR]']]");
上面只会给我 <img ...>元素。但我需要的是 <a href=""..>元素。
有人知道我做错了什么吗？
最佳答案
您可以使用following-sibling选择器获取下一个a sibling :
/html/body/pre/*[self::img[@alt='[DIR]']]/following-sibling::a
关于java - XPath 表达式获取另一个元素之后的元素，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/27549295/
