thanks for a file and log
problem is not in Locus, but in file.
You may copy it's content (or whole file) here and check it
http://www.xmlvalidation.com/You'll see that there are problems with texts (names). In valid XML file cannot be simply this
<name>Benni&Tanja</name>
You have to escape the '&' character or better put whole texts into CDATA, like this
<name><![CDATA[Benni&Tanja]]></name>
EDIT: just for your information. These three characters should never appear directly in plain text in xml '&', '<', '>' . Commonly wrote used '&', should be also written as '&' , so you may replace them
