Magpie removes angle brackets from RSS feed

I've found two WP installs on different servers, same WP version. Magpie returns different RSS content from same feed, one of the blogs returns the contents with angle brackets removed.

The XML is retrieved exactly the same for both blogs, the difference comes after calling Magpie($rss_content).

Here's the XML PHP config from both servers:

XML Support             active
XML Namespace Support   active

EXPAT Version           expat_1.95.7

lib开发者_开发知识库xml2 Version      2.7.3  <-- This one fails

Anyone knows what's causing this behavior?
