这几天制作一个系统的邮编区号查询功能，突发奇想制作了这个js+xml版的，因为xml数据量较大（2000多条记录），所以若是网速较慢的话，会有画面停顿的现象，我曾打算预加载xml数据，可惜没能实现（光找到了预加载图片的方法，你要知道预加载xml的方法可以告诉我，谢谢）。下面是邮编区号查询js+xml版的核心代码：
1、data.xml文件代码（这里只列了5条，明白他的结构就可以）：
<?xml version="1.0" encoding="gb2312"?
<!-- 邮编区号数据 --
<MyData
<Item Province="北京" County="北京" Zipcode="100000" Areacode="010" /
<Item Province="北京" County="通县" Zipcode="101100" Areacode="010" /
<Item Province="北京" County="昌平" Zipcode="102200" Areacode="010" /
<Item Province="北京" County="大兴" Zipcode="102600" Areacode="010" /
<Item Province="北京" County="密云" Zipcode="101500" Areacode="010" /
</MyData
2、index.htm文件代码（这个就是主界面拉）
<html
<head
<meta http-equiv="Content-Type" content="text/html; charset=gb2312"
<titlejs+xml的邮编区号查询</title
<style type="text/css"
