=head1 NAME
SVK::Log::Filter::XML - display log messages in XML format
=head1 SYNOPSIS
> svk log --xml
<?xml version="1.0" encoding="utf-8"?>
<log>
<logentry revision="1234" original="456">
<author>author</author>
<date>2006-05-16T15:43:28.889532Z</date>
<msg>This is the commit message for the revision.</msg>
</logentry>
</log>
> svk log --output xml
...
=head1 DESCRIPTION
The XML filter is an output filter for displaying log messages in XML format.
The organization of the XML format should be self-explanatory after a little
experimentation. The format is designed to be compatible with Subversion's
XML output, so you should be able to use tools like
L<http://ch.tudelft.nl/~arthur/svn2cl/> without any modification. However,
since SVK supports arbitary log filters (see L<SVK::Log::Filter> for details
on writing one), it may be easier to write your own output format than to
process the XML.
This filter is invoked implicitly when you specify the "--xml" argument to
SVK's log command. Two arguments to the log command modify XML's behavior.
=head2 quiet
Providing this command-line option to the log command prevents the XML filter
from displaying the contents of the log message. All other information is
displayed as usual.
=head2 verbose
Providing this command-line option to the log command makes the XML filter
display history information for each revision. The history includes the kind
of modification (modify, add, delete) and any copy history for each path that
was modified in the revision.
=head1 STASH/PROPERTY MODIFICATIONS
XML leaves all properties and the stash intact.
