Parsing address data from PAR and BREAK

I'm relatively new to XSLT. I need to extract legacy data from an XML =
representation of rich-text, and am having difficulty parsing around the =
<break> element. Specifically, I'm trying to reliably parse address =
information from this:

...
<tablecell borderwidth=3D'0px'>
<par def=3D'23'><run><font size=3D'9pt' name=3D'Arial' =
truetype=3D'false' familyid=3D'10'/>
123 E. Main Street<break/>Anytown, ST 12355<break/>USA</run>
<run><font size=3D'9pt' style=3D'bold' name=3D'Arial' truetype=3D'false' =
familyid=3D'10' color=3D'navy'/>
</run>
</par>
</tablecell>
...

<address>123 E. Main Street</address>
<city>Anytown</city>
<state>ST</state>
<zipcode>12355</zipcode>
<country>USA</country>

I'm using the Altova XSLT 2.0 engine. I've been poking around trying to =
find how this might be done, but am coming up short. Any suggestions =
will be much appreciated.
