用dom4j解析带命名空间的xml文件

1. SAXReadersaxReader=newSAXReader();
2. try{
3. Documentdocument=saxReader.read(newFile(filename));
4. Elementroot=document.getRootElement();
5. HashMapxmlMap=newHashMap();
6. xmlMap.put("plugins","http://www.**.com/yanfa/appmonschema");//http://www.**.com/yanfa/appmonschema为命名空间
7. XPathx=document.createXPath("//plugins:AppMonConfig/plugins:outputStrategy/plugins:monStrategy/plugins:item/plugins:targetId");//读取targetId节点
8. x.setNamespaceURIs(xmlMap);
9. ElementvalueElement=(Element)x.selectSingleNode(document);
10. System.out.println(valueElement.getText());//输出该节点内容
11. }catch(Exceptione){
12. }
