//这是第一个文件
<?xml version= "1.0 " encoding= "utf-8 " ?>
<gadget>
<name> mini Player! </name>
<namespace> miniPlayer </namespace>
<version> 1.0 </version>
<author name= "Mictel ">

<description> Vista 边栏工具 Windows mini Player! </description>
<icons>
<icon height= "128 " width= "128 " src= "icon.png "/>
</icons>
<hosts>
<host name= "sidebar ">
<base type= "HTML " apiVersion= "1.0.0 " src= "VistaMP.html " />
<permissions> full </permissions>
<platform minPlatformVersion= "1.0 " />
<defaultImage src= "icon.png "/>
</host>
</hosts>
</gadget>
//这是第二个文件
以上文件测试成功.得到的是XML文件的全部信息.我的想法是:不是得到全部的信息.我只要XML里的某一条信息..如:(Vista 边栏工具 Windows mini Player!).想求几位高手帮帮我..在第一个文件的基础上帮我完成这个功能.小弟感激不尽..不够可以再散分的..

xmldom = new ActiveXObject( "MSXML.DOMDocument ");
xmldom.loadXML(request.responseText);
alert(xmldom.selectSingleNode( "/gadget/name ").text);
alert(xmldom.selectSingleNode( "/gadget/description ").text)
