Hi!  
I have a title tag:  
\<TITLE\>Title - Old\</TITLE\>  
I want to change it to:  
\<TITLE\>Title - New\</TITLE\>

I tried the following:  
\<BODY\>  
\<SCRIPT\>  
var DocTitle = document.getElementsByTagName(“title”)[0];  
alert(DocTitle.nodeValue);  
\</SCRIPT\>  
\</BODY\>

The alert box gives a message “null”(IE). Hence, am not able to access the title tag text node and hence am not able to change the contents! Any suggesstions???
