我需要的输出应该是上述xml的子集,删除soap头和其他标记。如何在java中实现此输出

如果您有任何帮助,我们将不胜感激
我已尝试使用此线程中给出的示例:[1]:
下面是java代码
public static void main(String... args)
throws Exception
{
// String xml = "<A><B><id>0</id></B><B><id>1</id></B></A>";
String xml = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:ser=\"http://service.soap.oneflexi.com\"><soapenv:Header/><soapenv:Body><ser:processRequest><ser:in0><![CDATA[<BconRq language=\"SG\" currency=\"SGD\"><RqHeader><Date>20140614</Date><Time>162944</Time><TimeZone>GMT+06:00</TimeZone><MessageType>5320</MessageType><VersionNo>9005001</VersionNo><AppVersion>5.0.1</AppVersion><MerchantId>2003001</MerchantId><TerminalId>2004002</TerminalId><StanNo/><LastTxnRefNo/><OTP/></RqHeader><OfferMerchant/><OfferFlag>Y</OfferFlag><BconId>1234</BconId><Items><Item><ItemCode>VC01</ItemCode></Item></Items></BconRq>]]></ser:in0><ser:in4>?</ser:in4></ser:processRequest></soapenv:Body></soapenv:Envelope>";
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
Document doc = dbf.newDocumentBuilder().parse(new InputSource(new StringReader(xml)));
XPath xPath = XPathFactory.newInstance().newXPath();
Node result = (Node)xPath.evaluate(" Soapenv:Envelope/Soapenv:Body/ns:processRequestResponse/ns:return/BconRs[language=\"SG\"]", doc, XPathConstants.NODE);
// Node result = (Node)xPath.evaluate("A/B[id = '1']", doc, XPathConstants.NODE);
// Soapenv:Envelope/Soapenv:Body/ns:processRequestResponse/ns:return/BconRs[language="SG"]
System.out.println(nodeToString(result));
}
private static String nodeToString(Node node)
throws TransformerException
{
StringWriter buf = new StringWriter();
Transformer xform = TransformerFactory.newInstance().newTransformer();
xform.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
xform.transform(new DOMSource(node), new StreamResult(buf));
return(buf.toString());
}
publicstaticvoidmain(字符串…参数)
抛出异常
{
//字符串xml=“01”;

System.out.println(nodeToString(result));
}
私有静态字符串nodeToString(节点节点)
抛出TransformerException
{
StringWriter buf=新StringWriter();
Transformer xform=TransformerFactory.newInstance().newTransformer();
setOutputProperty(OutputKeys.OMIT_XML_声明,“yes”);
transform(新的DOMSource(节点),新的StreamResult(buf));
返回(buf.toString());
}
我可能认为XPATH遍历节点ItemRs时可能有错误,正如您也怀疑的那样,XPATH看起来不正确。您可能希望尝试以下简单的XPath:
//ItemRs[@language='SG']
要在XPath中引用属性,需要在属性名称的开头使用
@
。我尽量避免在XPath中提到名称空间前缀,因为通常我们需要以某种方式注册名称空间前缀到名称空间URI的映射(我不知道如何在Java中做到这一点,我更喜欢.NET).向我们展示您尝试过的Java代码。您可以尝试使用XML解析器或在最后一种情况下使用regex@Tichodroma:我已经添加了我尝试过的代码。
