XML Bulkupload produces validation error UrlContentResource

Hello all
I have created some xml to bulkupload, When fed to Kaltura it produces the following error which I don’t understand

	<?xml version="1.0" encoding="UTF-8"?><mrss><error>Log file is not ready: Error: Validate files failed on job [6636581042], Element 'urlContentResource': Character content is not allowed, because the content type is empty.
 at line 19 
Element 'urlContentResource': Character content is not allowed, because the content type is empty.

 at line 35 
Element 'urlContentResource': Character content is not allowed, because the content type is empty.
 at line 39 </error></mrss>

As I am trying to move media and flavours between Kaltura servers I have placed the urls derived from the api call
?service=media&action=getmrss

The error is occuring in the part of the xml that provides the url for the ingest process and I cannot see illeagal characters in this string
