Help! Can I have user defined extension function?

Question

Under SQL Sever XML, I can write a xsl script like this:
<msxsl:script language="JScript" implements-prefix="myfunc">
function getvalue(nodelist,name,istag){
var subNode=nodelist.nextNode();
if(subNode == null) return('?');
if(istag == '') name = '@' + name;
var value=subNode.getElementsByTagName(name);
return((value == null)?'':value);
</msxsl:script>
and I can call this function in the xsl, obviously, msxsl supported by microsoft. I know that Oracle XML support Extension function, but you can tell here that I want a user defined function while not a predefined function. Can I have such feature with Oracle XML, and How? Thanks.

Answer 1

Oracle XML support Extension function.
For example:
If we would like to import FAQDBUri.class with user-defined java functions, like TranslateDBUri(), we can write XSL file like this:
<xsl:template match="/" xmlns:dburig="http://www.oracle.com/XSL/Transform/java/FAQDBuri">
<xsl:variable name="urladd" select="dburig:TranslateDBUri($url)"/>
