Select a node with XPath whose child node contains a specific inner text
提问by D.R.
Given the following XML:
给定以下 XML：
<root>
<li><span>abcText1cba</span></li>
<li><span>abcText2cba</span></li>
</root>
I want to select all lielements having a spanchild node containingan inner text of Text1- using an XPath.
我想选择所有li具有包含内部文本的span子节点的元素- 使用 XPath。Text1
I started off with /root/li[span]and then tried to further check with: /root/li[span[contains(text(), 'Text1')]]
我从开始/root/li[span]，然后尝试进一步检查：/root/li[span[contains(text(), 'Text1')]]
However, this does not return any nodes. I fail to see why, can somebody help me out?
但是，这不会返回任何节点。我不明白为什么，有人可以帮我吗？

Just for readers. The xpath is correct. OP: Perhaps xpath parser didnt support the expression?
只为读者。xpath 是正确的。OP：也许 xpath 解析器不支持该表达式？
/root/li[span[contains(text(), "Text1")]]
回答by ViliamS
//li[./span[contains(text(),'Text1')]] - have just one target result
//li[./span[contains(text(),'Text')]] - returns two results as target
This approach is using something that isn't well documented anywhere and just few understands how it's powerful
这种方法使用的东西在任何地方都没有得到很好的记录，只有少数人了解它的强大之处
Element specified by Xpath has a child node defined by another xpath
Xpath 指定的元素有一个由另一个 xpath 定义的子节点

Try this XPath
试试这个 XPath
li/*[@innertext='text']

Your current xpath should be correct. Here is an alternative but ugly one.
您当前的 xpath 应该是正确的。这是另一种但丑陋的。
XmlNodeList nodes = doc.SelectNodes("//span/parent::li/span[contains(text(), 'Text1')]/parent::li");
We find all the span-tags. Then we find all the li-tags that has a span-tag as child and contains the 'Text1'.
我们找到了所有的跨度标签。然后我们找到所有具有 span-tag 作为子项并包含 'Text1' 的 li-tags。
OR simply:
或简单地：
//span[contains(text(), 'Text1')]/parent::li
//span[contains(text(), 'Text1')]/parent::li
