Xpath以获取带有href标记中匹配文本的第二个url [英] Xpath to get the 2nd url with the matching text in the href tag

问题描述

一个html页面具有分页链接，其中一个设置在页面顶部，另一个设置在页面底部.

A html page has paging links, 1 set at the top of the page and another on the bottom of the page.

使用HtmlUnit，我目前正在使用 getByAnchorText("1");

Using HtmlUnit, I am currently getting the HtmlAnchor on the page using getByAnchorText("1");

顶部的某些链接中有问题，因此我想使用XPath引用底部的链接.

There is a problem in some of the links on the top, so I want to reference the bottom links using XPath.

nextPageAnchor = (HtmlAnchor) page.getByXPath("");

如何使用xpath引用页面上的第二个链接?

How can I reference the 2nd link on the page, with using xpath?

我需要使用AnchorText来引用链接，因此链接如下:

I need to reference the link using the AnchorText, so a link like:

<a href="....">33</a>

href具有随机文本，并且是javascript函数，因此我不知道它会是什么.

The href has random text, and is a javascript function so I have no idea what it will be.

xpath可能吗?

推荐答案

要在文档中的任意位置选择第二个 a 元素:

To select the second a element anywhere in the document:

(//a)[2]

要在 href 属性中选择带有特定文本的第二个 a 元素，请执行以下操作:

To select the second a element with a particular text in the href attribute:

(//a[@href='...'])[2]

请注意，需要使用括号，并且表达式//a [2] 不会满足您的期望:它将选择所有 a 元素任何父级的第二个 a 元素.如果您输入的是

Note that the parantheses are required, and that the expression //a[2] will not do what you intend: it will select all a elements that are the second a element of any parent. If your input is

<p>Link <a href="one.html">One</a></p>
<p>Link <a href="two.html">Two</a> and <a href="three.html">Three</a>.</p>
<p>Link <a href="four.html">Four</a> and <a href="five.html">Five</a>.</p>

(//a)[2] 将返回第二个链接(two.html)，而//a [2] 将返回第三和第五个链接(three.html和Five.html)，因为它们都是父级的第二个 a 子级.

(//a)[2] will return the second link (two.html), while //a[2] will return the third and fifth link (three.html and five.html), since these both are the second a child of their parent.
