The Practical Extraction and Reporting Language (PERL), has long been a mainstay of server-side programming and a foundation of Common Gateway Interface (CGI) programming. Perl has been getting into XML in a big way, and one could easily write a book on the subject.
Perl modules are distributed at the Comprehensive Perl Archive Network (CPAN) site, www.cpan.org, and plenty of them deal with XML (I counted 156). You can find a selection of Perl XML modules, along with their descriptions as given on the CPAN site, in Table 20-2.
