求教js操作XML

有没有好的方法从下面的XML中找到ConID=51的PriceList节点的值,要求方法简单

  1.   

    用DOM 或者　SAX 都可以
      

  2.   

    var doc = new ActiveXObject("Msxml2.DOMDocument"); 
    //加载文档
    //doc.load("data.xml");//test
     var value="";
    var tables=doc.getElementsByTagName("Table2");
    for(var i=0;i<tables.length;i++)
    {
        var cNode=tables[i].getElementsByTagName("ConID");
         
        if(cNode!=null&&cNode[0]!=null&&cNode[0].firstChild!=null){    
        
             if(cNode[0].firstChild.data=="52")
             {
             
                var node=tables[i].getElementsByTagName("ConID");
                 if(node!=null&&node[0]!=null&&node[0].firstChild!=null){
                   value=node[0].firstChild.data;
                 }
                 else
                 {
                    value="";
                 }
                 break;
             }
         
         }
    }
      

  3.   

    var xmlDoc = new ActiveXObject("Microsoft.XMLDOM"); 
    xmlDoc.loadxml("messages.xml"); 
    xmlDoc.setProperty("SelectionLanguage", "XPath"); 
    var sPath = "//Table2/ConID/text()='51'"; 
    var bookNodes = xmlDoc.selectNodes(sPath);关于xpath可以看一下这里 http://www.blueidea.com/tech/program/2009/6635.asp 
      

  4.   

    var doc = new ActiveXObject("Msxml2.DOMDocument"); 
    //加载文档
    //doc.load("data.xml");//test
     var value="";
    var tables=doc.getElementsByTagName("Table2");
    for(var i=0;i<tables.length;i++)
    {
        var cNode=tables[i].getElementsByTagName("ConID");
         
        if(cNode!=null&&cNode[0]!=null&&cNode[0].firstChild!=null){    
        
             if(cNode[0].firstChild.data=="52")
             {
             
                var node=tables[i].getElementsByTagName("PriceList");  
                 if(node!=null&&node[0]!=null&&node[0].firstChild!=null){
                   value=node[0].firstChild.data;
                 }
                 else
                 {
                    value="";
                 }
                 break;
             }
         
         }
    }//因为楼主取的是同一父结点下面的另一个节点的值，所以用xpath不好取
      

  5.   

    var sPath = "//Table2/ConID/text()='51'";上面的大哥再帮我看看
      

  6.   

    var xmlDoc;
    if (window.ActiveXObject)
    {
    xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
    }
    else if (document.implementation.createDocument)
    {
    xmlDoc=document.implementation.createDocument("","",null);
    }
    else
    {
    alert('Your browser cannot handle this script');
    }
    xmlDoc.async=false;
    xmlDoc.loadXML(request.responseText);
    var x=xmlDoc.getElementsByTagName("LiveList");
    if (x.length>0)
    {
    for (var i=0;i<x.length;i++)
    {
    if (parseInt(x[i].getAttribute("ID"))>ArowNum)
    {
    document.getElementById("live").innerHTML+="<li>";
    document.getElementById("live").innerHTML+=x[i].getAttribute("ID")+":";
    ...
    document.getElementById("live").scrollTop=document.getElementById("live").scrollTop+200;
                                    ...这是我们之前用过的
    你自己看看
    根据这个改改就行
      

  7.   

    因为你是取的另一个节点，所以用Xpath是不好取的，不知道那位高手有办法，下面是我用我开始写的代码，做的测试，
    Value='4个成人高标全包价'    //load xml document 加载XML文件
        function _loadXmlDocument(xmlFilePath)

            var xmlDomVersions = ['MSXML2.DOMDocument.6.0','MSXML2.DOMDocument.3.0','Microsoft.XMLDOM'];
            for (var i = 0; i < xmlDomVersions.length; i++)
            {
              try
              {
                _xmlDoc = new ActiveXObject(xmlDomVersions[i]);
                break;
              }
              catch(e){}
            }
          }
          else if (document.implementation && document.implementation.createDocument)
          {
            try
            {
              _xmlDoc = document.implementation.createDocument('','',null);
            }
            catch(e){}
          }      if (_xmlDoc != null)
          {
            _xmlDoc.async = false;
            _xmlDoc.load(xmlFilePath);
          }      return _xmlDoc;
        }    //load xml string 加载 XML 字符串
        function _loadXmlString(xmlString)
        {
          var _xmlDoc = null;
          if (!window.DOMParser && window.ActiveXObject)
          {
            var xmlDomVersions = ['MSXML2.DOMDocument.6.0','MSXML2.DOMDocument.3.0','Microsoft.XMLDOM'];

                _xmlDoc.async = false;
                _xmlDoc.loadXML(xmlString);
                break;
              }
              catch(e){}
            }
          }

              domParser = new  DOMParser();
              _xmlDoc = domParser.parseFromString(xmlString, 'text/xml');
            }
            catch(e){}
          }      return _xmlDoc;
        }
        
      function test()
      {
    var doc = _loadXmlDocument("test.xml");
    if(doc==null)
    {
        alert("加载文档失败!");
        return;
    }
     
     var value="";
    var tables=doc.getElementsByTagName("Table2");
    alert(tables.length);
    for(var i=0;i<tables.length;i++)
    {
        var cNode=tables[i].getElementsByTagName("ConID");

             if(cNode[0].firstChild.data=="51")
             {
             
                var node=tables[i].getElementsByTagName("PriceList");
                 if(node!=null&&node[0]!=null&&node[0].firstChild!=null){
                   value=node[0].firstChild.data;
                 }
                 else
                 {
