[xsl] JAXP - Ignoring whitespaces from a Node object passed as parameter for XSLT transformation

[Blue Gecko <bluegecko@xxxxxxxxx>]

Hi all,

I'm facing with a problem concerning ignorable whitespace text nodes.

I use an XSLT stylesheet with the <xsl:strip-space elements="*"/> 
instruction in order to avoid any redundancy.
I pass a Node object (say: myNode -- see the attached code), obtained 
from an XPath evaluation, to the XSLT transformer as a parameter (named 
"siteMap"), but the resulting transformation preserves *just* and *only* 
the whitespaces coming from *that* parameter nodeset: it seems that the 
XSLT parser is unable to deal properly with pre-constructed nodesets.
I want to stress that the rest of the transformed content (from the main 
XML source) works perfectly (all whitespaces are stripped as expected).

Is this a standard-compliant behavior?
How can I force XPath resulting Node to ignore redundant whitespace text 
nodes?

Thanks in advance!

My code snippet:

import javax.xml.transform.*;
import javax.xml.xpath.*;
import org.w3c.dom.*;
import org.xml.sax.*;

{

[snip]

// Define the XPath evaluator!
XPath xPath = XPathFactory.newInstance().newXPath();

// Get the DOM representation of the root node via XPath evaluation!
Node myNode = (Node) xPath.evaluate(
 "/rootTag",
 new InputSource(sourcePath + "siteMap.xml"),
 XPathConstants.NODE
 );

[snip]

// Get the page xslt transformer!
Transformer pageTransformer = 
TransformerFactory.newInstance().newTransformer(pageStyle);
pageTransformer.setParameter("siteMap", myNode);
