RE: problem with namespaces .. [MORE INFO- looks like a bug]...us
ing the SimpleTransform example + e xamples
This appears to be a bug:
<PLAYTIME>
<rioport:min2sec>
<xsl:value-of select="TRACK_PLAYTIME/text()" />
</rioport:min2sec>
</PLAYTIME>
In the min2sec code I print out the child nodes of the Context node as
returned by XSLProcessorContext.getContextNode() [see code snippet below].
The child nodes printed out are the TRACK_PLAYTIME's parent's child nodes. I
tried using xsl:copy-of and got the same result.
for ( node = context.getContextNode().getFirstChild();
node != null; node = node.getNextSibling()) {
System.out.println(node.getClass().getName() );
if ( node.getNodeType() == Node.TEXT_NODE ) {
System.out.println("value:"+node.getNodeValue());
}
}

This is what I was alluding to in my earlier message. It's not a Xalan
bug. The context node for a template comes from the current node for
the template. The current node for the template is basically the node
which caused the template to be chosen. In your case, that is the
<TRACK> node. So, you'll get all of the children of the <TRACK> node.
The text nodes that you're seeing with just a newline for content are
the whitespace nodes between the various elements that are the children
of <TRACK>.
If I were you, I'd shelve the extension element and create an extension
function, passing the text time, like this:
<PLAYTIME>
<xsl:value-of select="rioport:min2sec(string(TRACK_PLAYTIME))"/>
</PLAYTIME>
I think this is what you want to do.
