Description Sean Owen 2007-09-05 12:13:08 UTC 
We have infrastructure to obtain line number from the source document via Saxon but so far have only used it in Java code. We need a working XSL-based example for everyone.
Comment 1 Roland G 2007-10-07 09:13:08 UTC 
DOMUtils.getNodeLineNumber(Node) in the XSLT returns an error.

The java function is used in the XSLT by:
xmlns:javaLineNumber="org.w3c.mwi.mobileok.basic.DOMUtils"
...
<xsl:value-of select="javaLineNumber:getNodeLineNumber(node())"/>
...
returns a:

  Error in call to extension function {public static int
  org.w3c.mwi.mobileok.basic.DOMUtils.getNodeLineNumber(org.w3c.dom.Node)}: Exception in

Comment 2 Roland G 2007-10-07 09:21:28 UTC 
actually there are problems to use DOMUtils.getNodeLineNumber(Node) in the XSLTs as a function.
could you check this problem and reassign me the bug?
