problems with link attribute in rss file

[aldm]

Hi,

I want to create rss file in php.
Everything works fine except one thing:

Link of rss <item> is http://www.[first_part]listingID=BC7486705&idxID=089 .
Link is OK, but items are not shown when xml is open.
I looked at source code of created xml and part idxID of every link in marked
with red color.
So, is idxID some special mark in xml and how can I make this work properly?

When I change link attribute of items, items are shown and everything works fine.

Thanks in advance,

Amer
