This class is of +interest to people writing Pod formatters based on Pod::Simple. + +Pod::Simple::DumpAsXML inherits methods from +L<Pod::Simple>. + + +=head1 SEE ALSO + +L<Pod::Simple::XMLOutStream> is rather like this class. +Pod::Simple::XMLOutStream's output is space-padded in a way +that's better for sending to an XML processor (that is, it has +no ignoreable whitespace). But +Pod::Simple::DumpAsXML's output is much more human-readable, being +(more-or-less) one token per line, with line-wrapping. + +L<Pod::Simple::DumpAsText> is rather like this class, +except that it doesn't dump with XML syntax. Try them and see +which one you like best! + +L<Pod::Simple>, L<Pod::Simple::DumpAsXML> + +The older libraries L<Pod::PXML>, L<Pod::XML>, L<Pod::SAX> + +=head1 SUPPORT + +Questions or discussion about POD and Pod::Simple should be sent to the +pod-people@perl.org mail list. Send an empty email to +pod-people-subscribe@perl.org to subscribe. + +This module is managed in an open GitHub repository, +L<http://github.com/theory/pod-simple/>.
