XML引擎版本的不同，給程序設計帶來諸多不便。將常見的幾個版本來個遍歷檢測，就能自動適應了。

<script?language="JavaScript">
var?objXML;
function?findXMLVersion()?{?
var?xmlVersion?=?["4.0",?"3.0",?"2.6",?"2.5",?"2",?"Microsoft",?"MSXML"];?
var?xmlDoc?=?"hellow?World";?
var?i,?objXml,?objXmlDom,?strRetVal="";
for?(i=0;?i?<=?xmlVersion.length-1;?i++)?{
if?(xmlVersion[i]?==?"Microsoft")?{?
?try?{?
??objXML?=?new?ActiveXObject("Microsoft.XMLDOM");?
??objXML.async?=?false;?
??if?(objXML.loadXML(xmlDoc))?{
????if?(strRetVal?==?"")?strRetVal?=?"Microsoft";?
??}
??}?catch?(e)?
??{?}
??}
?else?if?(xmlVersion[i]?==?"MSXML")?{?
?try?{?
??objXML?=?new?ActiveXObject("Msxml.DOMDocument");
??objXML.async?=?false;?
??if?(objXML.loadXML(xmlDoc))?{

findXMLVersion();
