Use old standalone XML with API

Has anyone been able to successfully use their old standalone XML files
with the API without modifying the XML. I've got a mapping application
that used that old stand alone and now I need to fix it to make it work
for the API (ok so I'm a bit late making the fix). Could you share the
javascript for it?

Example of old xml style

<?xml version="1.0"?>
<page>
<title>Page Title</title>
<query></query>
<center lat="38.9485326" lng="-92.322005"/>
<span lat="0.015" lng="0.015"/>
<overlay panelStyle="">

<location infoStyle="minipage.xsl" id="A">
<point lat="38.9485346" lng="-92.321805"/>
<icon image="marker.png" class="local"/>
<info>
<minipage>
<p>Insert custom HTML here for popup baloon</p>
</minipage>
</info>
</location>

</overlay>
</page>
