var XMLobj = (new DOMParser()).parseFromString(theString, "text/xml")

the problem that i am facing is the string that is to be passed to the parseFromString method is a xmlstring. i have an xml file stored in my local file system. but,when i read the file using javascript it is assigned to a javascript string n i m getting a parseerror when i try parse it using parseFromString method.

Have you checked that the XML file is valid?

i am storing a string obtained by converting a document fragment using the method serializeToStri ng in the xml file. The problem that i could figure out was the root element of the document fragment is not converted (only the child nodes are converted to string).So the resulting xml doc is not having a root element. How can i fix this??

Can you post the code that you've tried.

var serializer =Components.classes["@mozilla.org/xmlextras/xmlserializer;1"].createInstance(Components.interfaces.nsIDOMSerializer);
var string = serializer.serializeToString(this.rootnode);
 
var out = Components.classes["@mozilla.org/network/file-output-stream;1"].createInstance(Components.interfaces.nsIFileOutputStream);
out.init(this.file, 0x20 | 0x02, 0666, null);
out.write(string,string.length);
out.flush();
out.close();
