<script type="text/javascript"> //demo2 var xmlDoc = new ActiveXObject("Msxml2.DOMDocument"); xmlDoc.async = false; xmlDoc.loadXML("<a><![CDATA[aaaaaaaaaaaaaaaaaaaaa]]></a>"); root = xmlDoc.documentElement; for(i =0;i<root.childNodes.length;i++) { if(root.childNodes[i].nodeType==4) alert(root.childNodes[i].nodeValue) } </script> //demo3( for firefox) <!
