[英]Parsing SOAP Response in Java
I do not succeed in parsing a SOAP Response in Java (using Bonita Open Solution BPM). 我无法使用Java(使用Bonita Open Solution BPM)解析SOAP响应。 I have the following SOAP response (searching for a document in the IBM Content Manager; the SOAP Response returns 1 matching document)
我有以下SOAP响应(在IBM Content Manager中搜索文档; SOAP响应返回1个匹配的文档)

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: 我想获取文件名( ICCFileName =“ Golem_Artikel.txt” )和此文件的网址(< cm:URL value =“ http://cmwin01.ebusiness.local:9080 / icmrm / ICMResourceManager / A10 ... )(使用Java编写的字符串变量)中,我读了几篇有关如何执行此操作的文章( 无法处理SOAP响应 , 如何进行SOAP响应的解析 ),但没有成功,这是我尝试的方法:
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. 从Bonita,我仅获得responseDocumentBody或responseDocumentEnvelope(org.w3c.dom.Document)作为Web服务响应。 Therefore, I need to navigate from the SOAP Body to my variables.
因此,我需要从SOAP正文导航到我的变量。 I would be pleased if someone could help.
如果有人可以帮我,我会很高兴。
Best regards 最好的祝福
If you do a lot of work with this, I would definitively recommend using JAXB as MGoron suggests. 如果您为此做了大量工作,那么我绝对会建议按照MGoron的建议使用JAXB。 If this is a one shot excersize, XPATH could also work well.
如果这只是一杆大事,那么XPATH也可以很好地工作。
/*
* 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());
Below is the code to do this in VTD-XML , it basically consists of 2 XPath queries, each returning one result... however the code is robust as it doesn't assume those queries will return non-empty result... 下面是在VTD-XML中执行此操作的代码,它基本上由2个XPath查询组成,每个查询都返回一个结果...但是该代码很健壮,因为它不假定这些查询将返回非空结果...
