These class attributes are inserted by a JavaScript which isn't executed using Yahoo Pipes and Hpple.
Also the contents are loaded by ajax, you will have to trace the ajax calls and develop against this interface.
Using Firebug I could trace it loading
http://www.112.ru/publish/00/01/0508.01/2012/08//contents.xml
and lots of other "contents.xml" files which returned 404 errors. It contains contents in form of elements like
<view file="0901156380089d71_0508.01_00_01.full.shtml" format="full" indexed="true"/>
which seem to link again to some HTML snippets containing the actual data.
