The source code to this has been in SVN forever (/svnroot/amxmodx/dlls/csx/source/WinCSX).
Rather than write a program to address every user's separate needs, there's also an article on the wiki that describes how to write your own custom stats parser. There is an example in C# and in Perl:

The perl example is written such that you can just edit one section to output/filter the data.
