Problems with SDN RSS Feed - part 2

Another issue I am facing with RSS feeds is related to Craig's weblog /people/sap.user72/blog/2004/09/08/bsp-howto-exploring-bsp-development-and-the-miniwas-620-part-2 during the execution of the method GET_SDN_WEBLOG_BY_URL. This method contains, based on Brian's corresponding forum the following code:

collection = document->get_elements_by_tag_name( name = 'item' ).

WHILE index < collection->get_length( ).

... write entries to intrenal table

ENDWHILE.

However when I am calling using the RSS link http://weblogs.sdn.sap.com/pub/q/weblogs_rss?x-ver=1.0 the while command results in no entries reulting that no entries are being written to the internal table. I do not understand what the difference is with Brian's weblog since there this does not occur. The only difference is the RSS url. Has anyone faced this problem before and how do I solve it? Thanks, Tiest
