Select a node with XPath whose child node contains a specific inner text

Given the following XML:

<root>
    <li><span>abcText1cba</span></li>
    <li><span>abcText2cba</span></li>
</root>

I want to select all li elements having a span child node containing an inner text of Text1 - using an XPath.

I started off with /root/li[span] and then tried to further check with: /root/li[span[contains(text(), 'Text1')]]

However, this does not return any nodes. I fail to see why, can somebody help me out?

To check things in deeply nested children use .//* in your Xpath expression.

<div class="foo h1">
    <p>
      <span>
         <b>bar</b>
      </span>
    </p>
</div>

To find a div with class .foo which also contains a child with text bar just use the following xpath expression

$x('//div[contains(@class, "foo") and .//*[contains(text(), "bar")]]')

the xpath Kent Kostelac provided:

//span[contains(text(), 'Text1')]/parent::li

could be also be presented as so:

//li[span[contains(text(), 'Text1')]]

which is a bit shorter and provides improved readability by saying "give me the li that contains the span that displays 'Text1'"; instead of saying "can you see that span that dispalys 'Text1'? ok, so give me its li parent", which is what the original phrasing is actually saying.

//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

Element specified by Xpath has a child node defined by another xpath

Just for readers. The xpath is correct. OP: Perhaps xpath parser didnt support the expression?

/root/li[span[contains(text(), "Text1")]]

Your current xpath should be correct. Here is an alternative but ugly one.

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'.

OR simply:

//span[contains(text(), 'Text1')]/parent::li

Try this XPath

li/*[@innertext='text']
