+
+ <para>You may be tempted to develop your own Perl code for parsing XML.
+ After all, XML is text and Perl is a great language for working with
+ text. But before you go too far down that track, here are some points
+ to consider:</para>
+
+ <itemizedlist mark="bullet">
+
+ <listitem><para>Smart people don't. (Actually a number of really smart
+ people have - that's why there's a range of existing parsers to chose
+ from).</para></listitem>
+
+ <listitem><para>It's harder than you think. The first major hurdle is
+ <link linkend="encodings">encodings</link>. Then you'll have to handle
+ DTDs - even if you're not doing validation. The feature list will also
+ need to include numeric and named entities, CDATA sections, processing
+ instructions and well-formedness checks. You probably should support
+ namespaces too.</para></listitem>
+
+ <listitem><para>If you haven't done all that, it's not XML. It might
+ work for that subset of XML that you deem to be important, but if you
+ can't exchange documents with other parties, what's the
+ point?</para></listitem>
+
+ <listitem><para>Even if it works it will be slow.</para></listitem>

+ </itemizedlist>
+
+ <para>If none of the existing modules have an API that suits your needs,
+ write your own wrapper module to extend the one that comes closest.</para>
