一个实用的 Javascript XML to JSON Object 对象的转换 （JQuery）

一个实用的 Javascript XML to JSON  Object 对象的转换 （JQuery）

一个用来将xml文件转换成对象的插件

xml文件如下
<?xml version="1.0" encoding="UTF-8" ?>
<root>
<content>
  <plugins>TreeView</plugins>
  <plugins>ListGrid</plugins>
  <plugins>ListBox</plugins>
</content>
<pool>1</pool>
</root>

生成的对象为:



调用

var xml = $.loadXML("PluginConf.xml");
var obj = $(xml).toObject().get(0);
alert(obj.pool);
