Q:

parseKmlString fails with Cannot read property 'x'

I'm trying to parse a KML file passes as a string, and load it on to a google map. It works fine when I grab some KML from the geoxml site example see "kmlString1" but fails when I try to use my own extracted value, though I cant seem to see the difference and  the error is vague.
My map code:
geoMap = new google.maps.Map(document.getElementById('map-canvas'), myOptions);
                    geoXMLParser = new geoXML3.parser({ map: geoMap });
                    geoXMLParser.parseKmlString(kmlString1);
                    google.maps.event.trigger(geoMap, 'resize');

KML String 1 (works):

Is there a limitation with parseKmlString? The file loads fine with  geoXMLParser.parse("path/to/file") so I'm confused as to why it fails with the string value, which I need to use.

A:

You string has two XML declarations:
<?xml version="1.0" encoding="UTF-8"?><?xml version="1.0" encoding="UTF-8"?>

I copied and pasted into a KML document with one of those removed and it renders perfectly.  Admittedly the error was vague, but what helped me was to paste into NotePad++, format using the XML tools plugin, and do a validation.
