Dom4j 查找节点或属性
例如
1 查找下面xml中的student节点的age属性，
xpathstr="/students/student/@age";
2 查找下面xml中的student节点的telephone的值，
xpathstr="/students/student/telephone";
3 查找下面xml中的student节点的telephone的值，并且要满足name中包含“2030”，用到模糊查找
xpathstr="/students/student[contains("name","2030")]/telephone";
完整的xml文件：
<?xml version="1.0" encoding="UTF-8"?>
<students>
<student name="beijings2014" age="25">
<college>mobile</college>
<telephone>888</telephone>
</student>
<student name="shanghais2019">
<college>pc</college>
<telephone>999</telephone>
</student>
<student name="xi‘ans2030">
<college>pad</college>
<telephone>000</telephone>
</student>
</students>
具体方法：查找节点或属性,传入Document 和 xpathstr，此处Document 类型为 org.dom4j.Document，
如果用的是org.w3c.dom.Document则需要转换，可以看之前的一篇"
"
1 public String getContentString(Document document,String xpathstr){ 2 3 List list = document.selectNodes(xpathstr); 4 String result=""; 5 6 Iterator iter = list.iterator(); 7 iter = list.iterator(); 8 if (iter.hasNext()) { 9 10 Object o=iter.next(); 11 if(o instanceof Attribute){ 12 Attribute attribute = (Attribute) o; 13 //hm.put(attribute.getName(),attribute.getValue()); 14 result=attribute.getValue(); 15 if(debugf){ 16 System.out.println(attribute.getName()+":"+attribute.getValue()); 17 } 18 19 } 20 if(o instanceof Element){ 21 Element element = (Element) o; 22 String name = element.getName(); 23 String value = element.getText(); 24 //hm.put(name, value); 25 result=value; 26 if(debugf){ 27 System.out.println(name+":"+value); 28 } 29 } 30 } else { 31 return result; 32 } 33 return result; 34 }
