Firefox1.5: DOMParser.parseFromString() returns "[Document] null"

[sfeher]

Hi All,

The following code returns a valid xmlDoc (since I can evaluate and
selectNodes) but its value is "xmlDoc=[Document] null" ?! Or at least
this is what the FireBug shows and (xmlDoc===null) is true.

var parser = new DOMParser();
var xmlDoc = parser.parseFromString( responseText, "text/xml");
// at this point: xmlDoc=[Document] null

I'm a bit lost on what this actually means..

Any ideas?

Regards,
Sebastian

It might be that the output your tool shows you is first the name of the
variable, then its toString() result (which is [Document] so you have a
DOM Document there), then perhaps its nodeValue (which is null by
definition for document nodes).
But I am guessing, ask in a FireBug forum, I don't think that
alert(xmlDoc === null) will show true so that null must have some other
cause.

Thanks Martin,

That was indeed the case.
