xml的复杂解析取值和节点插入导出合并后的xml文件

如果你正准备 对xml进行解析,而这个xml里面元素放置不规则,个个节点的值取得麻烦,然后又想 往这个xml中随心所欲的插入节点,导出完整的xml文件, 那么请 that

public static String matchtoAppXml(String cpxml_path){

try {
InputStream in = null;
// 初始化XML解析
SAXBuilder builder = new SAXBuilder();
Document requestDoc = null;
requestDoc = builder.build(cpxml_path);
Element root = (Element)requestDoc.getRootElement();
Iterator list = root.getChildren().iterator();
while(list.hasNext()) {
//1-取得外挂信息
Element node = (Element) list.next();
String s_city="";
String s_name="";
String s_add="";
String s_tel="";
//System.out.println(node.getChild("Na").getAttributeValue("v"));
if (node.getChild("Na") != null) {
s_name = node.getChild("Na").getAttributeValue("v");
}
if (node.getChild("Add") != null) {
s_add = node.getChild("Add").getAttributeValue("v");
}

//查询xml重的某个字段如

- <Poi id="0">

<Na v="上海西门子开关有限公司" />

<Cla v="BA80" />

<Dis v="310112" />

<add v="上海市闵行经济技术开发区天宁路298号" />

<Tel v="021-24030000" />

- <Other>

<case n="from" v="elong" i="Y" />

<case n="city" v="北京" i="Y" />

<case n="url" v="http://www.powerproduct.com/user1/index.asp?id=12702" i="Y" />

<case n="fax" v="021-64924606" i="Y" />

</Other>

</Poi>

对应代码如下
if (XPath.selectSingleNode(node,"Other/case[@n='city']/@v")!= null) {
Attribute s_city_att = (Attribute)(XPath.selectSingleNode(node,"Other/case[@n='city']/@v"));
s_city = s_city_att.getValue();
}

//2-取得匹配得到的 俗名/经度纬度
Poi poi = getPoi(s_city,s_name,s_add,s_tel);

//3-插入外挂数据中
if(poi!=null){
Element pop=new Element("Pop");
//pop.setText("aaaa");
pop.setAttribute("v",poi.getName());
node.addContent(2,pop);//第二位插入

Element geo=new Element("Geo");
geo.setAttribute("lo",Integer.toString(poi.getLongitude()));
geo.setAttribute("la",Integer.toString(poi.getLatitude()));
node.addContent(3,geo);
}else{
node.removeContent();
}

}
//4-保存
XMLOutputter so=new XMLOutputter();
FileOutputStream fos = new FileOutputStream("d:/out.xml");
so.output(requestDoc,fos);

得到的out.xml的效果如下:

<Poi id="2">
<Na v="昆仑饭店" />

<Pop v="昆仑饭店" />

<Geo lo="11646273" la="3994418" />

<Cla v="2020" />

<Dis v="110105" />

<add v="北京朝阳区新源南路2号" />

<Tel v="010-65903388" />

- <Other>

<case n="from" v="derby" i="Y" />

<case n="city" v="北京" i="N" />

<case n="passportCode" v="P07000301DD77B864" i="N" />

<case n="url" v="http://api.51ditu.com" i="N" />

</Other>
