Markus,
The expression "exslt:node-set($def)/bo/totals" is not getting evaluated
because you list it in a non-xsl (<xsl:>) element. Because
<my:lineWeight> is not using the XSL namespace, the XSLT processor
thinks it is just an element that is to be copied to the output.
Therefore the value of your select attribute is just the string
"exslt:node-set($def)/bo/totals", and that is what your extension
function is receiving.
Try using
<my:lineWeight select="{exslt:node-set($def)/bo/totals}" />
in your XSLT code, which will tell the processor to evaluate the
expression (note the curly braces).

Hello,
I have a problem with my extension, because I didn't get it working to pass a

Does somebody know what I'm doing wrong? It seams that the SELECT-Attribute
wasn't executed.
thanks for your help
