I have an .xml doc with over 35,000 entries that I converted from an
Excel file. Each entry (element/person) has the typical firstname,
lastname, email, city, state child elements. I need to dynamically
tabulate the total number of people who live in each state. Is there a
way to do this with XSL, or Javascript?

This is for a Google Maps project. I'd like to be able to display the
number of Alumni living in each state in the mouseover window.


Sample XML:

<USalumni>
	<alum>
		<alumniID>1</alumniID>
		<firstname>John</firstname>
		<lastname>Doe</lastname>
		<email>jondoe@e...</email>
		<state>IL</state>
		<country>US</country>
	</alum>
	<alum>
		<alumniID>2</alumniID>
		<firstname>Sam</firstname>
		<lastname>Sonite</lastname>
		<email>samsonite@e...</email>
		<state>IL</state>
		<country>US</country>
	</alum>
	<alum>
		<alumniID>3</alumniID>
		<firstname>David</firstname>
		<lastname>Davidson</lastname>
