why doesn't get xml nodeValue in javascript?

Question

if (window.DOMParser) {
    parser=new DOMParser();
    xmlDoc=parser.parseFromString(txt,"text/xml");
}
else { // Internet Explorer 
    xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
    xmlDoc.async="false";
    xmlDoc.loadXML(txt); 
}
                /*copy ends*/
temp = xmlDoc.getElementsByTagName('COMMENT');
s0 = xmlDoc.getElementsByTagName('TITLE')[i].nodeValue;
s1 = xmlDoc.getElementsByTagName('CMT')[i].nodeValue;

s0 and s1 returned null and i dont understand why?

The nodeValue property of XML elements is always null, because the element content is actually stored within text nodes inside the element. If the content is simple enough, you can do something like:

s0 = xmlDoc.getElementsByTagName("TITLE")[i].firstChild.nodeValue;
s1 = xmlDoc.getElementsByTagName("CMT")[i].firstChild.nodeValue;
