problem with XercesparerLiaison
Hi, i have a problem with XercesparerLiaison
if i use it, for parse a xml document the xpath expresion than i
evaluate don´t work, the error is: "prefix must resolver to a namespace"
but if i use XalanSourceTreeParserLiaison with he same document and the
same xpath expresion the evaluation works fine...,
i need use XercesParserLiaison for use the method mapToXercesDocument,
<http://xml.apache.org/xalan-c/apiDocs/classXercesParserLiaison.html#a34>

hi i compiled Xalan-c with the new XercesParserLiaison and now works
fine! thanks for your help
When do you expect the new version of xalanc to be available?
thanks

I've diagnosed this as a bug in XercesParserLiason. Can you please open a
Jira defect that describes the problem?
I will provide a patch later today, which I will attach to the Jira
report.
Thanks!

Hi,
i remove the setParserLiason statement because XercesDOMSupport
don´t have this method.
I try this, now
expresion /:doc/:name[1]
this xml
<?xml version="1.0"?>
<doc>
<name first="David" last="Marston">Mr. Marston</name>
</doc>
and the result is correct, <name first="David" last="Marston">Mr.
Marston</name>
i don´t know how use namespaces whit XercesParserLiaison....
we have a problem?

Re: problem with XercesparerLiaison

If you remove the setParserLiason statement, how do you expect xalan to
traverse the xerces tree?
Try removing namespaces and then try to evaluate the expression. If it does,
then we have a problem.

Re: problem with XercesparerLiaison
Posted by Nacho Conde <ic...@tid.es>.
Maybe i not explained me correctly,
in SerializeNodeSet sample
1. change the XalanSourcetreeParseLiaison by XercesparseLiaison and
XalanSourceTreeDomSupport by XercesDOMSupport
2. remove the line theDOMSupport.setParserLiaison(&Liaison)
3. evaluate this expresion /foo:doc/foo:name[1]
the result is No nodes matched the location path /foo:doc/foo:name[1]
and now if you undo the changes, and evalute the same expresion with
XalanSourceTreeParseLiason the result is ok...
Can someone help me?

Sorry, here a code sample :
the code of evaluator:
XObjectPtr xobject(theEvaluator.evaluate(
theXercesDomSupport,
theDocument.getDocumentElement(),
XalanDOMString(xpathExpresion).c_str(),
theDocument.getDocumentElement()));
the xpath expresion

this expresion works ok, whit XalanSourcetreeParserliaison, but when i
use XercesParserLiaison dont work..
the evalute method can´t see the namespaces, i think...

You need to provide a complete, _minimal_ code sample along with a sample
input document and XPath expression for anyone to help you.
If you are constucting a Xerces DOM instance programmatically, you must
make sure you are creating a namespace-aware DOM. If you are parsing to a
Xerces DOM instance, you need to make sure the parser you're using is
properly configured for namespace processing.
