Not quite - you can create your own data structure:
<street>123 Elvis St.</street>
Notice how the tags describe what content they are holding - this is opposed to:
<tr><td>123 Elvis St.</td></tr>
Which tells you nothing about the information it contains.
Since the tags are descriptive, you can easily use XSLT to transform the <address> document into the XHTML document shown above, use XSLFO is present it however you want, use CSS to style the text, or dynamically import it client-side or server-side and extract information from it using SAX or DOM.
