Processing data after an empty tag.

I am using XSLT 1.0 and trying to find a way to transform the following SGML into XML.

SGML Input Supplied:

<para>
	<text> The following is a list <style type="list"></style><style type="para"></style>List Item One.
	<style type="para"></style>List Item Two.<style type="para"></style>List Item Three</text>
</para>

The problem I am trying to find a solution for is actually a problem in the sgml dtd.  It was poorly written and now I have to deal with it.
  <style> can contain no data, so instead of the <style> tag surrounding the data, it precedes the data and is an empty tag.
  
I was thinking that I could some how processing the parent <text> tag and 
determine what the style tag that precedes the text intended the output to be.
So far I have not found a way that work.  Any help would be appreciated.


XML Output Required:

<para>The following is a list. 
	<itemizedlist>
		<listitem><para>List Item One</para></listitem>
		<listitem><para>List Item Two</para></listitem>
		<listitem><para>List Item Three</para></listitem>
	</itemizedlist>
</para>
