解析string类型的xml字符串
我先拼接一个xml格式的字符串，模拟获取了这样的数据，然后再解析
所需要的包自行导入
StringBuilder sb = new StringBuilder();
sb.append("");
sb.append("");
sb.append(" ");
sb.append(" " + "this is a mark！"+ "");
sb.append(" ");
sb.append(" ");
sb.append(" ");
sb.append(" ");
sb.append(" " + "来解析我啊！"+ "");
sb.append(" ");
sb.append(" ");
sb.append(" ");
sb.append("");
//开始解析
String str= sb.toString();
Document doc = null;
try {
doc = DocumentHelper.parseText(str);
} catch (DocumentException e) {
e.printStackTrace();
}
Element root = doc.getRootElement();// 指向根节点
try {
Element mark=root.element("header").element("mark");
Element second=root.element("body").element("data").element("first").element("second");
//获取xml的节点内容
System.out.println(mark.getTextTrim());
System.out.println(second.getTextTrim());
}catch(Exception e){
e.printStackTrace();
}
运行结果：
