Parsing SOAP Response in Java
If you do a lot of work with this, I would definitively recommend using JAXB as MGoron suggests. If this is a one shot excersize, XPATH could also work well.
/*
* Must use a namespace aware factory
*/
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
Document doc = dbf.newDocumentBuilder().parse(...);
/*
* Create an XPath object
*/
XPath p = XPathFactory.newInstance().newXPath();
/*
* Must use a namespace context
*/
p.setNamespaceContext(new NamespaceContext() {
public Iterator getPrefixes(String namespaceURI) {
return null;
}
public String getPrefix(String namespaceURI) {
return null;
}
public String getNamespaceURI(String prefix) {
if (prefix.equals("ns1"))
return "http://www.ibm.com/xmlns/db2/cm/beans/1.0/schema";
if (prefix.equals("cm"))
return "http://www.ibm.com/xmlns/db2/cm/api/1.0/schema";
return null;
}
});
/*
* Find the ICCSFileName attribute
*/
Node iccsFileName = (Node) p.evaluate("//ns1:ICCSPArchivSuche/@ICCFileName", doc, XPathConstants.NODE);
System.out.println(iccsFileName.getNodeValue());
/*
* Find the URL
*/
Node url = (Node) p.evaluate("//ns1:ICCSPArchivSuche/cm:resourceObject/cm:URL/@value", doc, XPathConstants.NODE);
System.out.println(url.getNodeValue());

I do not succeed in parsing a SOAP Response in Java (using Bonita Open Solution BPM). I have the following SOAP response (searching for a document in the IBM Content Manager; the SOAP Response returns 1 matching document)
<soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <soapenv:Body> <ns1:RunQueryReply xmlns="http://www.ibm.com/xmlns/db2/cm/beans/1.0/schema" xmlns:ns1="http://www.ibm.com/xmlns/db2/cm/beans/1.0/schema"> <ns1:RequestStatus success="true"></ns1:RequestStatus> <ns1:ResultSet count="1"> <ns1:Item URI="http://xxxx/CMBSpecificWebService/CMBGetPIDUrl?pid=96 3 ICM8 ICMNLSDB16 ICCSPArchivSuche59 26 A1001001A12D18B30015E9357518 A12D18B30015E935751 14 1087&server=ICMNLSDB&dsType=ICM"> <ns1:ItemXML> <ICCSPArchivSuche ICCCreatedBy="EBUSINESS\iccadmin" ICCCreatedDate="2012-04-18T10:51:26.000000" ICCFileName="Golem_Artikel.txt" ICCFolderPath="" ICCLastModifiedDate="2012-04-18T10:51:28.000000" ICCLibrary="Dokumente" ICCModifiedBy="EBUSINESS\iccadmin" ICCSharePointGUID="c43f9c93-a228-43f9-8232-06bdea4695d1" ICCSharePointVersion="1.0 " ICCSite="Archiv Suche" cm:PID="96 3 ICM8 ICMNLSDB16 ICCSPArchivSuche59 26 A1001001A12D18B30015E9357518 A12D18B30015E935751 14 1087" xmlns:cm="http://www.ibm.com/xmlns/db2/cm/api/1.0/schema"> <cm:properties type="document"> <cm:lastChangeUserid value="ICCCMADMIN"/> <cm:lastChangeTime value="2012-04-18T11:00:15.914"/> <cm:createUserid value="ICCCMADMIN"/> <cm:createTime value="2012-04-18T11:00:15.914"/> <cm:semanticType value="1"/> <cm:ACL name="DocRouteACL"/> <cm:lastOperation name="RETRIEVE" value="SUCCESS"/> </cm:properties> <cm:resourceObject CCSID="0" MIMEType="text/plain" RMName="rmdb" SMSCollName="CBR.CLLCT001" externalObjectName=" " originalFileName="" resourceFlag="2" resourceName=" " size="702" textSearchable="true" xsi:type="cm:TextObjectType"> <cm:URL value="http://cmwin01.ebusiness.local:9080/icmrm/ICMResourceManager/A1001001A12D18B30015E93575.txt?order=retrieve&item-id=A1001001A12D18B30015E93575&version=1&collection=CBR.CLLCT001&libname=icmnlsdb&update-date=2012-04-18+11%3A00%3A15.001593&token=A4E6.IcQyRE6_QbBPESDGxK2;&content-length=0"/> </cm:resourceObject> </ICCSPArchivSuche> </ns1:ItemXML> </ns1:Item> </ns1:ResultSet> </ns1:RunQueryReply> </soapenv:Body> </soapenv:Envelope>
I would like to get the filename (ICCFileName="Golem_Artikel.txt") and the url to this file ( <cm:URL value="http://cmwin01.ebusiness.local:9080/icmrm/ICMResourceManager/A10...) in string Variables using Java. I read several articles on how to do this (Can't process SOAP response , How to do the Parsing of SOAP Response) but without success. Here is what I tried:
import javax.xml.parsers.DocumentBuilder; import javax.xml.parsers.DocumentBuilderFactory; import org.w3c.dom.Document; import org.w3c.dom.Element; import org.w3c.dom.Node; import org.w3c.dom.NodeList; import org.xml.sax.InputSource; // Clean response xml document responseDocumentBody.normalizeDocument(); // Get result node NodeList resultList = responseDocumentBody.getElementsByTagName("ICCSPArchivSuche"); Element resultElement = (Element) resultList.item(0); String XMLData = resultElement.getTextContent(); // Check for empty result if ("Data Not Found".equalsIgnoreCase(XMLData)) return null; DocumentBuilder documentBuilder = DocumentBuilderFactory.newInstance().newDocumentBuilder(); InputSource inputSource = new InputSource(); inputSource.setCharacterStream(new StringReader(XMLData)); Document doc = documentBuilder.parse(inputSource); Node node = doc.getDocumentElement(); String result = doc.getNodeType(); return result;
From Bonita, I only get responseDocumentBody or responseDocumentEnvelope (org.w3c.dom.Document) as webservice response. Therefore, I need to navigate from the SOAP Body to my variables. I would be pleased if someone could help.
Best regards
