Error parsing stylesheet

Question

I'm writing a function that will take a query and a stylesheet as parameters (varchar2), generate xml from the query, format the output using the supplied stylesheet and return it to the calling program.
I've based the function on code examples I've found on the web, so apologies if this isn't actually xml db.
The stylesheet is well-formed, according to xmlspy.
I've reduced the call down to this - xmldoc := dbms_xmlparser.parse(xsl);
This is the error:
Error at line 1

I haven't posted the whole stylesheet, as I reckon the error is probabaly pretty basic, but I can't find out what it is.
I've got rather confused with the different ways I've found to manipulate xml in Oracle!
Thanks,

Answer 1

Thanks for that.
When you say 'If you really want to keep on using DBMS_XMLPARSER', does that mean it's been deprecated?
I've been thrown in the deep end here and pointed to a Toad knowledge base article which had a helper function I was advised to use as a start point.
There was no mention of any Oracle version, so I assumed it worked for all; I guess that is not the case.
Anyway, your simpler version looks just that. What documentation can I look at to understand what's going on ?
All I've found so far refers to the parser or xmltype, which is further than we need to go at the moment.
I've implemented your simpler version, but still get the same error; I'm guessing that my xml is still wrong.
Which raises another question.
I was wrong when I said the stylesheets were working in our production system; they are in our live 8i system, but we haven't run that part in our new 11g system yet, apart from what I'm trying to do now.
Do I assume things have changed in that area and our stylesheets will no longer work?
Here's the new output.
