dom4j及xpath基础应用

Jdom:对于小型xml处理就好
dom4j:对于大文件优与jdom，故选择dom4j

SAXReader reader = new SAXReader();             
		Document document = reader.read(new File("E:/F/wks_alms_custom_dep/CapitalSimulExplain/temp/result.xml"));

Element element = root.element("result");
		Element stepListElement = element.element("stepList"); 
		List<Element> stepElements = stepListElement.elements("step");

使用xpath，需要引入jar包：jaxen-1.1.6.jar


使用xpath获得element
List<Attribute> selectNodes = document.selectNodes("/resultList/result/stepList/step");

使用xpath获得Attribute
List<Attribute> selectNodes = document.selectNodes("/resultList/result/stepList/step/@elapsedTime");
System.out.println(selectNodes.get(1).getData());
