JS处理xml特殊字符

本周使用cell表结合xmlhttp组件开发异步多行数据插入操作,遇到数据为&时发生xml解析错误

Reflector和google后发现
是由于特殊字符造成,需要进行处理:
<转化成&lt;
>转化成&gt;
‘转化成&apos;
“转化成&quot;
&转化成&amp;

在W3C的技术规范中,也可以看到这样的字符不允许出现:
http://www.w3.org/TR/2001/REC-xml-c14n-20010315

于是找了一个javascript的htmlEncode函数:

         HTMLEncode = function( text )
     {
    if ( typeof( text ) != "string" )
        text = text.toString() ;

     text = text.replace(
       /&/g, "&amp;").replace(
       /"/g, "&quot;").replace(
        /</g, "&lt;").replace(
        />/g, "&gt;") ;

     return text ;
     }

 问题解决,使用时:

前台js拼凑xml string:

        function GetString(iRow)
         {
                 s1 = HTMLEncode(form1.DCellWeb1.GetCellString(2,iCurrentRow,0)); 
                  s2 = HTMLEncode(form1.DCellWeb1.GetCellString(3,iCurrentRow,0));
                  s3 = HTMLEncode(form1.DCellWeb1.GetCellString(4,iCurrentRow,0));
                  s4 = HTMLEncode(form1.DCellWeb1.GetCellString(5,iCurrentRow,0));
           
            return "<xml version='1.0' encoding='GB2312'><data>"+
            "<s1>"+s1+"</s1>" +
            "<s2>"+s2+"</s2>" +
            "<s3>"+s3+"</s3>" +      
            "<s4>"+s4+"</s4>" +                
            "</data></xml>"   
         }
 

后台c#解析:

string sProjCode, sProjName, sUnitName, sManager, sDirectionCode;

         System.Xml.XmlDocument xDoc = new System.Xml.XmlDocument();
         xDoc.Load(Request.InputStream);

         sProjCode = HttpUtility.HtmlDecode(xDoc.GetElementsByTagName("s1")[0].InnerText.Trim());
         sProjName = HttpUtility.HtmlDecode(xDoc.GetElementsByTagName("s2")[0].InnerText.Trim());
         sUnitName = HttpUtility.HtmlDecode(xDoc.GetElementsByTagName("s3")[0].InnerText.Trim());
         sManager = HttpUtility.HtmlDecode(xDoc.GetElementsByTagName("s4")[0].InnerText.Trim());
