Replying to Extracting "attributed" Data From An Xml Document/data-island

OK, so my XML data looks like this:

<xml id = "internalXMLData">

<Contacts>
<Contact>
<Name>Jonnie Graham</Name>
<Phone type="home">(09) 3888 466</Phone>
<Phone type ="mobile"/>
<Phone type ="work"/>
<email>jonnie@poomail.com</email>
<email>jonnie@shitmail.com</email>
</Contact>

<Contact>
<Name>Andre Sapeas</Name>
<Phone type="home"/>
<Phone type="mobile">(123) 456 3757</Phone>
<Phone type="work"/>
<email>info@somedomain.co.nz</email>
<email>andre_sapeas@somedomain.com</email>
</Contact>
<Contacts>

</xml>

...see how there is more than 1 "type" of phone number, and more than 1 possible email address?

to reference, say the Name, we would write: <span datafld="Name">, but how would we reference each "type" of phone number (or in other words how woud one reference each specifically/uniquely attributed phone number?), -for example??

Thanks heaps!
