NAME

       Bio::Variation::IO::xml - XML sequence variation input/output stream

SYNOPSIS

       Do not use this module directly.  Use it via the Bio::Variation::IO class.

DESCRIPTION

       This object can transform Bio::Variation::SeqDiff objects to and from XML file databases.

       The XML format, although consistent, is still evolving. The current DTD for it is at
       <http://www.ebi.ac.uk/mutations/DTDE/seqDiff.dtd>.

REQUIREMENTS

       To use this code you need the module XML::Twig which creates an interface to XML::Parser
       to read XML and modules XML::Writer and IO::String to write XML out.
