JScript讀取XML檔案

     JScript讀取XML檔案需要考慮msxml組件的多個版本，穩妥的做法是將所有版本都列出來。

xml檔案的內容如下：

[html]
<?xml version="1.0" encoding="GB2312" ?>  
<Binary> 
     <Item name="a.exe" /> 
     <Item name="b.dll" /> 
     <Item name="c.dll" /> 
</Binary>  

<?xml version="1.0" encoding="GB2312" ?>
<Binary>
     <Item name="a.exe" />
     <Item name="b.dll" />
     <Item name="c.dll" />
</Binary> 

 

讀取該xml檔案的JScript如下：

[javascript]
main(); 
 
function main()  
{ 
var xmlDoc = null; 
       var signatures = [ 
                   "Msxml2.DOMDocument.6.0", 
                   "Msxml2.DOMDocument.5.0", 
                   "Msxml2.DOMDocument.4.0", 
                   "Msxml2.DOMDocument.3.0", 
                   "Msxml2.DOMDocument", 
                   "Microsoft.XmlDom"]; 
        for (var index = 0; index < signatures.length; index++)  
      { 
            try { 
                xmlDoc = new ActiveXObject(signatures[index]); 
                 } 
            catch (e)  
        { 
                //繼續嘗試更低版本  
                        } 
        }    
xmlDoc.async = false; 
xmlDoc.resolveExternals = false; 
var strXmlPath = “D:\\test.xml”; 
xmlDoc.load(strXmlPath); 
if (xmlDoc.parseError.errorCode != 0) 
      { 
            var myError = xmlDoc.parseError; 
            WScript.Echo("開啟xml檔案失敗: " + myError); 
        } 
        else  
       { 
            var BinGroup = xmlDoc.getElementsByTagName("Item"); 
                             for (var i = 0; i < BinGroup.length; i++) 
                { 
                                          var strBinName = BinGroup.item(i).getAttribute("name"); 
                                  WScript.Echo(strBinName); 
            }  
         } 
} 

main();

function main()
{
var xmlDoc = null;
       var signatures = [
                   "Msxml2.DOMDocument.6.0",
                   "Msxml2.DOMDocument.5.0",
                   "Msxml2.DOMDocument.4.0",
                   "Msxml2.DOMDocument.3.0",
                   "Msxml2.DOMDocument",
                   "Microsoft.XmlDom"];
        for (var index = 0; index < signatures.length; index++)
      {
            try {
                xmlDoc = new ActiveXObject(signatures[index]);
                 }
            catch (e)
  {
                //繼續嘗試更低版本
                        }
        } 
xmlDoc.async = false;
xmlDoc.resolveExternals = false;
var strXmlPath = “D:\\test.xml”;
xmlDoc.load(strXmlPath);
if (xmlDoc.parseError.errorCode != 0)
      {
            var myError = xmlDoc.parseError;
            WScript.Echo("開啟xml檔案失敗: " + myError);
        }
        else
       {
      var BinGroup = xmlDoc.getElementsByTagName("Item");
                             for (var i = 0; i < BinGroup.length; i++)
        {
                                          var strBinName = BinGroup.item(i).getAttribute("name");
                               WScript.Echo(strBinName);
   }
         }
}
