[jQuery] Problems parsing XML with jQuery

[Gissur Þórhallsson]

I'm trying to parse this little XML document here:
http://pastebin.com/m5f0e4300 with this code: function(response) {
console.log(response.responseText) console.log(response.responseXML) try {
console.log("Try and find nafn")
console.log($j(response.responseXML).find("nafn").text())
console.log($j(response.responseXML).find("LM:nafn").text()) } catch(e) {
console.log("WMS GetFeatureInfo XML Error") } }
(JS code: http://pastebin.com/m5efc6214 )
And for some reason I get the following from the Firebug log:

[The xml text]
Document [A Document object of the XML]
Try and find nafn
[Empty line]
[Empty line]

Instead of those Empty lines I would like to get "Kópavogur".
Anybody have any idea what I'm doing wrong?

Kind regards from Iceland,
