Consider simple XML document:
<html><body>
<table>
<tr><td> Item 1</td></tr>
<tr><td> Item 2</td></tr>
</table>
</body></html>
Using XPath /html/body/table/tr/td/text() we will get
[" Item 1", " Item 2"].
Is it possible to trim white space, for example using normalize-space() function to get this?
["Item 1", "Item 2"]
normalize-space(/html/body/table/tr/td/text()) yields trimmed contents of only the first td tag ["Item 1"]

What is XPath? XPath is a major element in the XSLT standard. XPath can be used to navigate through elements and attributes in an XML document. XPath stands for XML Path Language. XPath uses "path like" syntax to identify and navigate nodes in an XML document.
Using XPath "/html/body/table/tr/td/text()" we will get [" Item 1", " Item 2"].
Is it possible to trim white space for example using normalize-space() function to get ["Item 1", "Item 2"]?
Not in XPath 1.0.
In Xpath 2.0 this is simple:
/html/body/table/tr/td/text()/normalize-space(.)
In XPath 2.0 a location step of an XPath expression may be a function reference. This is used in the expression above to produce a sequence of xs:string items, each of which is the result of applying normalize-space() on the context node (any node selected by the subexpression that precedes the last location step).
