XOM API for Processing XML with Java

["Bhaskar Maddala" <maddalab AT gmail.com>]

Hello,

   I receive a request that conforms to an xml schema, the schema definition
fragment is as follows

  <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"; xmlns="
http://schemas.mycompany.com/2007/pro"; targetNamespace="
http://schemas.mycompany.com/2007/pro"; elementFormDefault="qualified">
   <xsd:complexType name="BusinessObjectsType">
       <xsd:sequence minOccurs="1" maxOccurs="unbounded">
           <xsd:element minOccurs="0" name="RequestSettings"
type="RequestSettingsType" />
           ....
       </xsd:sequence>
   </xsd:complexType>
  </xsd:schema>

  From my limited understanding I do not believe the client is restricted in
using any namespace prefix when creating a xml that conforms to the schema
definition above.

  Here is an example of the xml I receive for processing

<?xml version="1.0" encoding="UTF-8"?>
<ns1:BusinessObjects xmlns:ns1="http://schemas.mycompany.com/2007/pro";>
   <ns1:RequestSettings>
         ....
   </ns1:RequestSettings>
</ns1:BusinessObjects>

  I use the following code to retrieve a nu.xom.Document instance

            Builder builder = new Builder();
            StringReader reader = new StringReader(request);
            Document document = builder.build(reader);

   When I attempt to do the following
   Nodes nodes = m_document.query("BusinessObjects/RequestSettings");

   nodes.size() is zero. I think this is because XPath is Namespace aware
and I need the prefix ns1 in the query XPath expression.

  Question : Currently I do not know the prefix used by the client making
the request, is there any way in XOM for me to retrieve the prefix so that I
can use it elsewhere, or better yet is there an option that would allow the
existing query to work?


Thanks
