XML有关问题，读取一个网页的信息，把读取到的信息按照个数输出到浏览器下

var xmlParse = function(str) 
{
    if (typeof ActiveXObject != 'undefined' && typeof GetObject != 'undefined') 
    {
        var doc = new ActiveXObject('Microsoft.XMLDOM');
        doc.loadXML(str);
        return doc;
    }

    if (typeof DOMParser != 'undefined') 
    {
        return (new DOMParser()).parseFromString(str, 'text/xml');
    }
    return createElement('div', null);
}

var xml = '<?xml version="1.0" encoding="UTF-8"?>\
<term seqno="1">\
 <command name="help" app=" sunflyspa">\
  <commandName>dll</commandName>\
  <commandName>set</commandName>\
  <commandName>sip</commandName>\
  <commandName>logfilesize</commandName>\
  <commandName>monitor</commandName>\
  <commandName>about</commandName>\
 </command>\
</term>';
var doc = xmlParse( xml );

function getNodeValues( root ) {
    var values = [];
    var attrs = root.attributes;
    for( var i = 0; attrs && i < attrs.length; i++ ) values.push( attrs[ i ].nodeName + ':' + attrs[ i ].nodeValue );
    if( root.nodeType == 3 && root.nodeValue.replace( /^\s+|\s+$/g, '' ) ) values.push( root.nodeValue );
    var children = root.childNodes;
    for( var i = 0; i < children.length; i++ ) {
        values = values.concat( getNodeValues( children[ i ] ) ) 
    }
    return values;
}

var result = getNodeValues( doc.documentElement );
alert( result )

------解决方案--------------------

你可以用XMLHTTP到后台读取。
