for the same rss 2.0 feed, http://sopai.net/topten.xml

i update it successfully in my localhost (drupal4.6.1 +php4.3.11+iis+win xp professional)
but when i update it in my site (drupal.zxwybbs.com/drupal4.6.1+php4.3.10+apache+debian), it appears a parse feed error at line, and without the line number)

How strange it is!
And what should I do to make it updateable in my site?
