As Michael describes, this is the job of a parser.

The old osgmlnorm utility (part of the opensp package) does exactly
this. Assuming your file is called main.xml, you can type

$ osgmlnorm -wxml sgmlxml.dec main.xml

The -wxml switches from SGML to XML, and you will need a copy of the
SGML Declaration for XML (there's a copy at
http://xml.silmaril.ie/downloads/sgmlxml.dec if you can't find one
elsewhere).

This will write to standard output, so you can redirect it into a file
or a subsequent process.

Downside: it IS a normalizer, so all REQUIRED attributes will be
included, but the output will be a single XML file.
