[jdom-interest] XPath problems using JDom

[Bhave, Ameya]

Hi,

I have read some of the literature on this subject in the archives, and am
still unable to sort my problem out. Basically I am trying to read an xml
file using an xpath expression.

My xml file looks like this:

------
<?xml version="1.0" encoding="UTF-8"?>
<OTA_AirLowFareSearchRQ EchoToken="0" MaxResponses="20" Mode="MasterPricer"
SequenceNmbr="0" Target="Amadeus" xmlns="
http://www.opentravel.org/OTA/2003/05"
xmlns:helper="xalan://com.openjaw.rules.XSLHelper" xmlns:xalan="
http://xml.apache.org/xalan">
    <POS>
        <Source ISOCurrency="GBP" PseudoCityCode="1AC">
            <ns1:RequestorID ID="H6265/AAA/32835/2006/41000/OPENJAW/MERLIN"
ID_Context="ABTA" xmlns:ns1="http://www.opentravel.org/OTA/2003/05"
xmlns:ns2="http://www.tui-uk.co.uk/OTA_EXT/2006" xmlns:ns3="
http://www.openjawtech.com/2005" xmlns:ns4="
http://www.opentravel.org/OTA/2002/08"/>
        </Source>
    </POS>
    <OriginDestinationInformation>
        <DepartureDateTime>2007-10-23T00:00:00.000+01:00</DepartureDateTime>
        <OriginLocation CodeContext="IATA" LocationCode="LGW"/>
        <DestinationLocation CodeContext="IATA" LocationCode="PMI"/>
    </OriginDestinationInformation>
    <OriginDestinationInformation>
        <DepartureDateTime>2007-10-30T00:00:00</DepartureDateTime>
        <OriginLocation CodeContext="IATA" LocationCode="PMI"/>
        <DestinationLocation CodeContext="IATA" LocationCode="LGW"/>
    </OriginDestinationInformation>
    <TravelerInfoSummary>
        <AirTravelerAvail>
            <PassengerTypeQuantity Code="ADT" Quantity="2"/>
            <PassengerTypeQuantity Code="CHD" Quantity="3"/>
        </AirTravelerAvail>
    </TravelerInfoSummary>
</OTA_AirLowFareSearchRQ>

------

And the code to access the info (using xpath) is:

-------
public static void getXPathValue(File file)
   {
      Document xmlDoc = getDocumentForFile(file);

      try
      {
//         XPath.setXPathClass(org.jaxen.jdom.JDOMXPath.class);
         XPath xPath = XPath.newInstance
("/ota:OTA_AirLowFareSearchRQ/ota:OriginDestinationInformation");
         xPath.addNamespace("ota", "http://www.opentravel.org/OTA/2003/05");
//default ns

         xPath.addNamespace("helper",
"xalan://com.openjaw.rules.XSLHelper");
         xPath.addNamespace("xalan", "http://xml.apache.org/xalan");
         xPath.addNamespace("ns2", "http://www.tui-uk.co.uk/OTA_EXT/2006");
         xPath.addNamespace("ns1", "http://www.openjawtech.com/2005");
         xPath.addNamespace("ns3",
"http://www.opentravel.org/OTA/2002/08");





         List nodes = xPath.selectNodes(xmlDoc);
         System.out.println("Nodes = " + nodes);

      }
      catch (Exception e)
      {
         System.out.println("Error: " + e);
         e.printStackTrace(System.out);
      }
}
-------

The problem is that the list I get is empty.
