solution for extracting faultstring from SOAP FAULT EXCEPTION

Help me to find out a good solution.

Is there any optimal way of extracting fault string from the SOAP FAULT EXCEPTION. i have provided my code how retrieved the fault string.

Parent and Children elements inside SOAP FAULT EXCEPTION
[ <con:errorCode>BEA-382500</con:errorCode>, <con:reason>yyyyyy</con:reason>,
<con:details>
<con1:ReceivedFaultDetail xmlns:con1="<http://www.bea.com/wli/sb/stages/transform/config>">
<con1:faultcode>soapenv:Server</con1:faultcode>
<con1:faultstring>ERR-666666 : error messsage here</con1:faultstring>
<con1:detail>
<ns7:ServiceException xmlns:S="<http://xsi:nil="true">
</ns7:ServiceException>
</con1:detail> <con1:http-response-code>500</con1:http-response-code> </con1:ReceivedFaultDetail>
</con:details>, <con:location><con:node>PipelinePairNode1</con:node><con:pipeline>PipelinePairNode1_request</con:pipeline><con:stage>checkAndDetermineBillingCycles1</con:stage><con:path>request-pipeline</con:path> </con:location>]

public static String getFaultString( SOAPFaultException soa)  {
		String faultString ="";	
				
		Iterator entries = getDetailEntries(soa);
		if( entries!=null ){
			
			while ( entries.hasNext() ) {	
				
				DetailEntry newEntry = (DetailEntry)entries.next();	
				
				if( newEntry!=null ){
					
					final Iterator childElementsIter = newEntry.getChildElements();
					
					if( childElementsIter!=null ){
						
						while ( childElementsIter.hasNext() ) {
							
							final SOAPElement soapElement = (SOAPElement)childElementsIter.next();								
							String strName = getSOAPElementName(soapElement);	
							
							if( strName!=null && strName.equals("details") ) {
								
								final Iterator childElementsIter1 = soapElement.getChildElements();
								
								if( childElementsIter1!=null ){
									while ( childElementsIter1.hasNext() ) {
										
										final SOAPElement soapElement1 =(SOAPElement)childElementsIter1.next();													
										String strName1 = getSOAPElementName(soapElement1);	
										
										if( strName1!=null && strName1.equals("ReceivedFaultDetail") ) {	
											final Iterator childElementsIter2 = soapElement1.getChildElements();
											
											if( childElementsIter2!=null ){
												
												while ( childElementsIter2.hasNext() ) {
													
													final SOAPElement soapElement2 =(SOAPElement)childElementsIter2.next();
													
													String strName2 = getSOAPElementName(soapElement2);	
													
													if( strName2!=null && strName2.equals("faultstring") ) {
														
														faultString = soapElement2.getValue();	
														
														break;
													}	
												}//childElementsIter2
											}
										}
									}	//while childElementsIter1	
								}
							}											
						}
					}// while childElementsIter
				}	// newEntry	
			}//while entries
		}
		return faultString;
	}

XPATH SOLUTION

I am getting SOAPFaultException on the fly and getting cause of the exception. This cause contains XML string to find out respective fault string.

How do i parse and feed soapfaultexception or cause into xpath methods?

How do I get value from the following node faultstring which is 3 layers down
detail
ReceivedFaultDetail
faultstring
