<!--<br /> <br /> Code highlighting produced by Actipro CodeHighlighter (freeware)<br /> http://www.CodeHighlighter.com/<br /> <br /> --> <? xml version="1.0" encoding="gbk" ?> < check > < result > 3 </ result > < record > < CUNIT > 个人 </ CUNIT > </ record > < record > < CUNIT > 河北移动 </ CUNIT > </ record > < record > < CUNIT > 测试 </ CUNIT > </ record > </ check >把它存成一个xml文件，放到服务器. 使得在浏览器地址栏输入“http://localhost/test/data.xml”时可以打开它。 然后就是我们的页面了，当然这个页面只有一个下拉框。html代码如下：
