XML, the latest and best markuplanguage for self-describing data, is becoming the generic datapackaging format of choice. Perl, which web masters have long reliedon to stitch up disparate components and generate dynamic content, isa natural choice for processing XML. The shrink-wrap of the Internetmeets the duct tape of the Internet.</p><p>More powerful than HTML, yet less demanding than SGML, XML is aperfect solution for many developers. It has the flexibility toencode everything from web pages to legal contracts to books, and theprecision to format data for services like SOAP and XML-RPC. Itsupports world-class standards like Unicode while beingbackwards-compatible with plain old ASCII. Yet for all its power, XMLis surprisingly easy to work with, and many developers consider it abreeze to adapt to their programs.</p><p>As the Perl programming language was tailor-made for manipulatingtext, Perl and XML are perfectly suited for one another. The onlyquestion is, "What's the best wayto pair them?" That's where thisbook comes in.</p><div class="sect1"><a name="perlxml-PREF-SECT-1" /><h2 class="sect1">0.1. Assumptions</h2><p>This book was written for programmers who are interested in usingPerl to process XML documents. We assume that you already know Perl;if not, please pick up O'Reilly's<em class="citetitle">Learning Perl</em><a name="INDEX-1" />(or itsequivalent) before reading this book. It will save you muchfrustration and head scratching.</p><p>We do not assume that you have much experience with XML. However, ithelps if you are familiar with markup languages such as HTML.</p><p>We assume that you have access to the Internet, and specifically tothe <a name="INDEX-2" /> <a name="INDEX-3" />ComprehensivePerl Archive Network (CPAN), as most of this book depends on yourability to download modules from CPAN.</p><p>Most of all, we assume that you've rolled up yoursleeves and are ready to start programming with Perl and XML.There's a lot of ground to cover in this littlebook, and we're eager to get started.</p></div><hr width="684" align="left" /><div class="navbar"><table width="684" border="0"><tr><td align="left" valign="top" width="228"><a href="copyrght.htm"><img alt="Previous" border="0" src="../gifs/txtpreva.gif" /></a></td><td align="center" valign="top" width="228"><a href="index.htm"><img alt="Home" border="0" src="../gifs/txthome.gif" /></a></td><td align="right" valign="top" width="228"><a href="ch00_02.htm"><img alt="Next" border="0" src="../gifs/txtnexta.gif" /></a></td></tr><tr><td align="left" valign="top" width="228">Copyright Page</td><td align="center" valign="top" width="228"><a href="index/index.htm"><img alt="Book Index" border="0" src="../gifs/index.gif" /></a></td><td align="right" valign="top" width="228">0.2.
