Question

我有一个模块，它使用web服务并从中获取响应。我得到的响应包含一个值，我需要在其中设置它的值。我正在使用XPath。现在当我在本地系统上运行此功能时，我得到了所需的输出，但是当我在耳边使用它时，它无效。

耳中的代码：

private static String stResponsePath="//Envelope//Body//AddNoteResponse//Response//";
private static String Fault_Path="//Envelope/Body/Fault/detail/CSIApplicationException/ServiceProviderEntity/";

/**
 * Construct AddNoteResponse bean from 
 * 
 * @param addNote response SOAP XML
 */
public AddNoteResponse createAddNoteResponseFromSoapString(String soapString)throws EDDSystemException
{
    try
    {
        Document soapDocument =AddNoteDomParserHelper.convertStringToDoc(soapString);       
        // EDDLog.outLog.info("soapDocument " + soapDocument.getFirstChild());
        // EDDLog.outLog.info("soapDocument " + soapDocument.getLastChild());

        EDDLog.outLog.info("soapString :" +soapString );
        AddNoteResponse addNoteResponse= new AddNoteResponse();
        addNoteResponse.setCode(AddNoteDomParserHelper.**getElementValue**(stResponsePath + "code", soapDocument));
        addNoteResponse.setDescription(AddNoteDomParserHelper.**getElementValue**(stResponsePath + "description", soapDocument));
    } .....
      .....
}   

public static String **getElementValue**(String elementName, Document doc) throws Exception
    {
        String value = "";
        XPath xPath = XPathFactory.newInstance().newXPath();
        if(xPath ==null)
        {
            EDDLog.outLog.info(" xpath is  null");
        }
        EDDLog.outLog.info("doc " + doc.getFirstChild());
        NodeList docNodes = (NodeList) xPath.evaluate(elementName,doc, XPathConstants.NODESET);
        // NodeList docNodes = (NodeList) xPath.evaluate("/Envelope/Body/AddNoteResponse/Response/code",doc, XPathConstants.NODESET);   
        EDDLog.outLog.info("elementName :" +elementName );

        //NodeList docNodes = doc.getElementsByTagNameNS("*", elementName);
        if (docNodes == null || docNodes.getLength() == 0) {
            docNodes = doc.getElementsByTagName(elementName);
            EDDLog.outLog.info("docNodes.getLength() :"+docNodes.getLength());
        }

输出是：

但是当我在本地系统上尝试相同的代码时，它运行正常：

Entering .convertStringToDoc()...
Exiting .convertStringToDoc()...
soapDocument [SOAP-ENV:Envelope: null]
9
 xpath is not null
elementName :/Envelope/Body/AddNoteResponse/Response/code
docNodes length:1
value :0
docNodes length2:1
addNoteResponse.getCode
 xpath is not null
elementName :/Envelope/Body/AddNoteResponse/Response/description
docNodes length:1
value :Success
docNodes length2:1

这是我正在处理的回复：

我感兴趣的价值是：

<cng:code>0</cng:code>
<cng:description>Success</cng:description>

Xpath功能
