在JAVA中使用XPath解析具有不同名称空间的xml

要使用Java中的命名空间进行XPath查询，我相信您需要执行以下操作：

XPath xpath = XPathFactory.newInstance().newXPath();xpath.setNamespaceContext(new NamespaceContext() {    @Override    public String getNamespaceURI(String prefix) {        switch (prefix) { case "env":     return "http://schemas.xmlsoap.org/soap/envelope/"; case "ns2":     return "http://abc.examples.com/";        }        return XMLConstants.NULL_NS_URI;    }    @Override    public String getPrefix(String namespaceURI) {        throw new UnsupportedOperationException("Not supported yet.");    }    @Override    public Iterator getPrefixes(String namespaceURI) {        throw new UnsupportedOperationException("Not supported yet.");    }});Node getNewTokenResp =      (Node) xpath.evaluate("/env:Envelope/env:Body/ns2:getNewTokenResponse",      document, XPathConstants.NODE);

您还需要先调用

.setNamespaceAware(true)

documentBuilderFactory

documentBuilder
