Collogues，我有循环创建具有nessesary结构的soap xml（不要询问结构）
log.info("Body elements: ");
NodeList nodeList = body.getElementsByTagName("*") ;
for (int i = 0; i < nodeList.getLength(); i++) {
Node node = nodeList.item(i);
if (node.getNodeType() == Node.ELEMENT_NODE) {
log.info(node.getNodeName());
if (node.getNodeName().equals("ns2:request")) {
log.info("Set namespace and prefix for " + node.getNodeName());
SOAPElement childX = (SOAPElement) node;
childX.removeNamespaceDeclaration(childX.getPrefix()) ;
childX.addNamespaceDeclaration("ns3", "http://mayacomp/Generic/Ws");
childX.setPrefix("ns3");
}
else {
if (node.getNodeName().equals("ns2:in") ) {
log.info("Remove namespace for " + node.getNodeName());
SOAPElement childX = (SOAPElement) node;
childX.removeNamespaceDeclaration(childX.getPrefix()) ;
childX.addNamespaceDeclaration("", "");
childX.setPrefix("");
}
SOAPElement childX = (SOAPElement) node;
childX.removeNamespaceDeclaration(childX.getPrefix()) ;
childX.setPrefix("");
}
}
}
结果我收到了xml：
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<ns3:request xmlns:ns3="http://mayacomp/Generic/Ws">
<in xmlns="http://mayacomp/Generic/Ws">
<requestHeader>
我的问题是如何仅从xmlns="http://mayacomp/Generic/Ws"元素中删除<in>并接收：
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<ns3:request xmlns:ns3="http://mayacomp/Generic/Ws">
<in>
<requestHeader>
更新
我尝试配置xml元素：
/*Config body elements*/
while (itBodyElements.hasNext())
{
Object o = itBodyElements.next();
SOAPBodyElement bodyElement = (SOAPBodyElement) o;
log.info("Elements from 'Body' element = " + bodyElement.getLocalName() );
Iterator it2 = bodyElement.getChildElements();
while (it2.hasNext())
{
Object requestElement = it2.next();
SOAPBodyElement bodyRequest = (SOAPBodyElement) requestElement;
log.info(" Elements from '"+ bodyElement.getLocalName() + "' element = " + bodyRequest.getLocalName());
log.info(" Delete namespace from IN element " + bodyRequest.getLocalName());
bodyRequest.removeNamespaceDeclaration(bodyRequest.getPrefix());
bodyRequest.setPrefix("");
Iterator it3 = bodyRequest.getChildElements();
while (it3.hasNext())
{ //work with other elements
但它对'in'元素没有影响。跑完后我还有：
<in xmlns="http://mayacomp/Generic/Ws">
更新
我通过将ws称为下一个解决了这个问题：
getWebServiceTemplate().marshalSendAndReceive(
"URL",
request,
new WebServiceMessageCallback()
{ public void doWithMessage(WebServiceMessage message) {
SaajSoapMessage saajSoapMessage = (SaajSoapMessage)message;
SOAPMessage soapMessage = UtilsClass.createSOAPMessage(in);
saajSoapMessage.setSaajMessage(soapMessage);
}
}
);
方法 createSOAPMessage 使用javax.xml.soap库配置soap消息。

如果我正确理解了这个问题，您的代码将获得以下XML作为输入：
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<ns2:request xmlns:ns3="http://mayacomp/Generic/Ws">
<ns2:in>
<ns2:requestHeader>
您希望将其转换为以下XML：
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<ns3:request xmlns:ns3="http://mayacomp/Generic/Ws">
<in>
<requestHeader>
在这种情况下，调整名称空间声明和名称空间前缀是不够的，因为在DOM中in和requestHeader元素仍将位于http://mayacomp/Generic/Ws名称空间中。这是因为DOM元素的名称空间URI是在创建/解析时确定的，并且在以后添加或删除名称空间声明时不会更改。当序列化DOM时，序列化程序将自动生成必要的名称空间声明，以确保输出中的元素有效地具有DOM中的名称空间。这就是为什么在输出中得到xmlns="http://mayacomp/Generic/Ws"的原因，尽管DOM中没有该命名空间声明。
您真正需要做的是更改这些元素的名称空间URI。遗憾的是，DOM节点没有setNamespaceURI方法，您需要使用Document.renameNode。

您可以使用
之类的内容删除该属性 XPath xPath = XPathFactory.newInstance().newXPath();
NodeList nList = (NodeList)xPath.evaluate("/Envelope/Body/request/in", body, XPathConstants.NODESET);
for (int i = 0; i < nList.getLength(); ++i) {
Element e = (Element) nList.item(i);
e.removeAttribute("xmlns");
}
以下测试显示它确实有效。
@Test
public void removeXmlns() throws Exception {
String xml = "" +
"<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\">\n" +
" <soapenv:Body>\n" +
" <ns3:request xmlns:ns3=\"http://mayacomp/Generic/Ws\">\n" +
" <in xmlns=\"http://mayacomp/Generic/Ws\">\n" +
" <requestHeader>\n" +
" </requestHeader>\n" +
" </in>\n" +
" </ns3:request>\n" +
" </soapenv:Body>\n" +
"</soapenv:Envelope>";
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(ResourceUtils.getFile("/soaptest.xml").getAbsolutePath());
Element body = document.getDocumentElement();
XPath xPath = XPathFactory.newInstance().newXPath();
NodeList nList = (NodeList)xPath.evaluate("/Envelope/Body/request/in", body, XPathConstants.NODESET);
for (int i = 0; i < nList.getLength(); ++i) {
Element e = (Element) nList.item(i);
e.removeAttribute("xmlns");
}
DOMSource domSource = new DOMSource(document);
StringWriter writer = new StringWriter();
StreamResult result = new StreamResult(writer);
TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer();
transformer.transform(domSource, result);
logger.info("XML IN String format is: \n" + writer.toString());
}
输出
2015-11-26-11-46-24[]::[main]:(demo.TestCode.removeXmlns(TestCode.java:174):174):INFO :TestCode:XML IN String format is:
