XSLT: How to show the Tag NAME?

[Gabriel Cane]

I'm writing an XSL file to transform an XML file into HTML. What I would like to know is how would I output the NAME of the tag I'm dealing with.
For example:
For an XML file (elements.xml)
<PERIODIC_TABLE>
<ATOM>Hydrogen</ATOM>
<MOLLECULE>H20</MOLLECULE>
</PERIODIC TABLE>
What would I need in my XSL to output the following HTML:
<p>ATOM</p>
<p>MOLLECULE</p>
I know how to output the text within the tags (Hydrogen or H20) and the attributes. It's getting the name of the tags I haven't been able to figure out.
Thanks.

There is name() function right for it!
