text() XPath 选择器中的重复选择 [英] duplicate selection in text() XPath selector

问题描述

我正在尝试选择文本中包含某个单词(例如:公司)的所有节点，因为该单词需要有一个注册标记.

I'm trying to select all nodes with text that contain a certain word (ex: Company) because the word needs to have a register mark.

这是 XHTML 的一部分(这个

在表格单元格内).

Here is part of the XHTML (this <p> is inside a table cell).

<p>
  <strong>
    <a style="color:#0E5A8B; text-decoration:none" target="_blank" href="http://www.trekk.com">
      <span class="title">
        A Company Content Title
      </span>
    </a>
    <br />
    <span style="color:#000000">

  </strong>

  <a style="color:#000" target="_blank" href="http://www.trekk.com">

我将 XHTML 加载到 System.Xml.XmlDocument 并尝试使用

I load the XHTML into a System.Xml.XmlDocument and try to select the nodes using

NewsletterHtmlDoc.SelectNodes("//*[contains(text(),'Company')]")

生成的 XmlNodeList 包含 2 个 XmlNode.

The resulting XmlNodeList contains 2 XmlNodes.

1. with InnerText = 公司内容标题 2010 年 2 月 23 日上午 10:00PT 样本内容立即注册

1. <p> with InnerText = A Company Content Title February 23, 2010 10:00 A.M. PT Sample Content Register now

with InnerText = 公司内容标题

<span class="title"> with InnerText = A Company Content Title

我的目标是只选择第二个，<span> 标签，我不确定为什么 <p> 标签也被选中.如果它选择了

，但为什么它不也选择 或 ，以及为什么不是包含

?

My goal is to just select the 2nd one, the <span> tag and am not sure why <p> tag is also being selected. If it selects <p>, but why wouldn't it also select the <strong> or <a>, and why not the <table> or <td> that contain the <p>?

推荐答案

我想通了.Sample Content 文本是

元素的 InnerText 的一部分，并导致

元素的整个 InnerText被发现.将 Sample Content 放在它自己的元素中，从

元素中删除了任何直接的 InnerText 并解决了问题.

I figured it out. The Sample Content text was part of the InnerText of the <p> element and caused the entire InnerText of the <p> element to be found. Putting Sample Content in its own element removed any immediate InnerText from the <p> element and fixed the problem.
