<p class=MsoNormal><span lang=EN-CA>Hello,<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-CA><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-CA>I’m having some problem using
xmerl_xpath on a document having namespaces. I’m not sure I fully
understand how all of this work and the problem should not come from
xmerl_xpath, but from my misunderstanding of xml, namespace, xpath…<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-CA>It seems that with xpath, it’s
mandatory to give the namespace.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-CA><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-CA>For instance, in a document like this:<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-CA style='font-family:"Courier New"'><o:p> </o:p></span></p>

<p class=MsoNormal><span lang=EN-CA style='font-family:"Courier New"'><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-CA>If I want to get all “element”
attributes, I need to do a query like <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-CA style='font-family:"Courier New"'>xmerl_xpath:string("//xs:simpleType",
X)<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-CA>Is there a way to not having to give the
namespace in the query ??<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-CA>Another related question is the usage of
{namespace, …} option in the query. What is it’s usage ? A tried
something like this<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-CA style='font-family:"Courier New"'>xmerl_xpath:string("//simpleType",
X, [{namespace, X#xmlElement.namespace}]).<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-CA>Hoping for a miracle… Of course, no
miracle :-)<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-CA>I don’t understand what do this
option.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-CA><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-CA>My problem is that I get different schema
“element”s, which are in two different namespaces. I can’t
see how to retrieve them using xpath.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-CA>One namespace is declared in the root
element, so I can get it’s definition and add the namespace manually when
building the query, but in the case above, the namespace is defined in the
schema node itself, so I can’t get it.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-CA><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-CA>If anybody can give me some highlight or pointers,
this would help me a lot ! :-)<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-CA><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-CA>Thanks<o:p></o:p></span></p>
