Re: Custom Processor with XPath

[Castyn]

Good to know.  I have the body properly converting to a Document now.

I suppose this may end up more of an XPath question, so I apologize in
advance but I have looked everywhere for some complicated examples and
haven't had much luck.

Let's say this is the document that is coming into my custom processor and
being converted to a Document:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/";>
        <soap:Body>
                <ns2:hotelContentResponse
xmlns="http://atp.abv.com/schema/common/ATPCommonServiceTypes/v1"; 
                                                                 
xmlns:ns2="http://atp.abc.com/schema/hotel/hcm/content/serviceDataTypes/v1"; 
                                                                 
xmlns:ns3="http://atp.abc.com/schema/hotel/hcm/content/dataTypes/v1"; 
                                                                 
xmlns:ns4="http://atp.abc.com/schema/common/content/serviceDataTypes/v1";>
                        <header>
                                <language isoCountryCode="US" 
isoLanguageCode="en" /> 
                                <headerVersion build="" major="1" minor="0" /> 
                                <transactionStatus 
overallStatusArea="HOTELCONTENT"
overallStatusCode="0000" overallStatusDescription="OK"
transactionSuccessful="true" /> 
                                <serviceTransactionDuration 
endTime="2011-11-21T11:21:46.906-05:00"

                        </header>
                        <ns2:hotelContent>
                                <ns4:contentList attributeNumber="718" 
name="Airport Details">
                                        <ns4:compound attributeId="1390159538" 
attributeNumber="718"
name="Airport Details" valueChangeDate="2009-07-01T04:00:00.000">
                                                <ns4:textLine 
attributeId="1390159539" attributeNumber="719"
name="Airport Code" valueChangeDate="2009-07-01T04:00:00.000">
                                                        
<ns4:text>ATL</ns4:text> 
                                                </ns4:textLine>
                                        </ns4:compound>
                                        <ns4:compound attributeId="1390159538" 
attributeNumber="718"
name="Airport Details" valueChangeDate="2009-07-01T04:00:00.000">
                                                <ns4:textLine 
attributeId="462364234" attributeNumber="719"
name="Airport Code" valueChangeDate="2009-07-01T04:00:00.000">
                                                        
<ns4:text>NYC</ns4:text> 
                                                </ns4:textLine>
                                        </ns4:compound>
                                </ns4:contentList>
                        </ns2:hotelContent>
                </ns2:hotelContentResponse>
        </soap:Body>
</soap:Envelope>

I am trying to get a Node List of the airport codes (in this doc ATL and
NYC).  What I have been trying is 

XPath xpath = XPathFactory.newInstance().newXPath();            
XPathExpression expr = xpath.compile("//textLine[attributeNumber='719']");
                
NodeList nodes = (NodeList)expr.evaluate(payload, XPathConstants.NODESET);
            
for (int i = 0; i < nodes.getLength(); i++) {
   // Do Stuff
}               

I am not sure if the document needs to have other information attached to it
such as XML version for xpath to treat it properly or if it is something
else, but I haven't been able to get any nodes returned at all on the
document, even when trying expressions as simple as "//hotelContent" and
such.  Is there something I am missing?
