Should exsltFuncFunctionComp() be compiling it's contents? Currently
it calls xsltParseTemplateContent(), but not xsltInitElemPreComp()
(or similar function).
The impact is that if you make the mistake of putting content
directly in your <func:function>, you get:
xsltApplySequenceConstructor: value-of was not compiled
and no clue where the bug in your script is. If your script also
has text nodes, you get:
xsltApplySequenceConstructor: value-of was not compiled
ELEMENT fake
element fake: error : Node has no parent
TEXT
content=
{http://xml.juniper.net/test}test-func: cannot write to result tree while
executing a function
xmlXPathCompiledEval: evaluation failed
runtime error: file /tmp/te30.xsl line 5 element value-of
XPath evaluation returned no result.
which is much more helpful. Would compiling the contents of the
function help get a better error to the user?
Examples appended (with and without text nodes).
Thanks,
Phil
