XPath: Problem with inline elements

[Rainer]

Hello everybody,

I have a question concerning XPath expressions. Consider this XML
snippet:

<foo title="an attempt">
<ul>
<li>This works fine</li>
<li>Before the inline element <em>Inside the inline element</em> after
the inline element</li>
<li>This also works fine</li>
</ul>
</foo>

In order to reach the first list element, I would use the XPath
expression "/foo/ul/li[1]", which works fine. (I get the first list
element with "This works fine", as expected.)

However, I need an XPath expression that returns the second list
element in three "portions":
- "Before the inline element "
- "Inside the inline element"
- " after the inline element"

I can get the inside of the inline element with "/foo/ul/li/em", but I
have no idea how to get the surrounding strings. Any ideas?

Kind regards,

Rainer

the inline element</li>

However, I need an XPath expression that returns the second list
element in three "portions":
- "Before the inline element "
- "Inside the inline element"
- " after the inline element"

This will return the text descendants of the <li> elements:

/foo/ul/li//text()
