getElementsByTagName("pspagetitle")[x] is undefined

The following code is giving me the error “xmldoc.getElementsByTagName(“pspagetitle”)[x] is undefined”. Having said that I can not for the life of me figure it out. I have been staring at this for two hours and I decided to put my ego aside and ask for some help. I know that this something simple I just can’t put my finger on it. So if there are any gurus out there that can help me it would be appreciated.

Note: The initial request for the document is working fine, if I place an alert [I]alert(typeof root);[/I] it returns object and [I]alert(root)[/I]; returns [object HTMLCollection]. I have also included a copy of my XML document (via inline comment) that is being loaded via XMLHttpRequest()

[CODE]
//var xmldoc = http_request.responseXML;
root = xmldoc.getElementsByTagName(“portalsettings”);

alert(typeof root); // <– returns object
alert(root); // <– returns [object HTMLCollection]

for(x = 0; x <= root.length; x++)
{
/*

// The following line is the one causing my eventual brain aneurysm.
var m_pageTitle = xmldoc.getElementsByTagName(“pspagetitle”)[x].childNodes[0].nodeValue;
var m_customerName = xmldoc.getElementsByTagName(“pscustomername”)[x].childNodes[0].nodeValue;

//Not entirely sure this next line is right.. I have not been able to get past the original problem.
var m_psHeadEndUrl = xmldoc.getElementsByTagName(“psheadend”)[x].childNodes[0].childNodes[0].nodeValue;

$(‘#highlight-black’).append(‘<strong>’ + m_pageTitle + ‘</strong>’);
document.title = m_pageTitle;
alert(m_psHeadEndUrl);
}
[/CODE]

Thank you,
