Can anyone please suggest an XPath expression format that returns a string value containing the concatenated values of certain qualifying child nodes of an element, but ignoring others:
<div>
This text node should be returned.
<em>And the value of this element.</em>
And this.
<p>But this paragraph element should be ignored.</p>
</div>
The returned value should be a single string:
This text node should be returned. And the value of this element. And this.
Is this possible in a single XPath expression?
Thanks.

As defined in the W3 XPath 1.0 Spec, " child::node() selects all the children of the context node, whatever their node type." This means that any element, text-node, comment-node and processing-instruction node children are selected by this node-test.
For the div element with an id attribute of hero //div[@id='hero'] , these XPath expression will select elements as follows: //div[@id='hero']/* will select all of its children elements. //div[@id='hero']/img will select all of its children img elements. //div[@id='hero']//* will select all of its descendent elements.
The key part of this XPath is *[1] , which will select the node value of the first child of Department .
In XPath 2.0 :
string-join(/*/node()[not(self::p)], '')

In XPath 1.0:
You can use
/div//text()[not(parent::p)]
to capture the wanted text nodes. The concatenation itself cannot be done in XPath 1.0, I recommend doing it in the host application.
