Variable number of attributes

I'm trying to produce a single style sheet (foo.xsl) that offers the
following functionality. I'm using IE 5.5. Any help would be greatly
appreciated.

Having a document:

<doc>
	<ele name1="A1" name2="A2"/>
	<ele name1="B1" name2="B2"/>
</doc>

processed through the style sheet (foo.xsl) produces:

<TABLE>
	<TR>
		<TH>name1</TH>
		<TH>name2</TH>
	</TR>
	<TR>
		<TD>A1</TD>
		<TD>A2</TD>
	</TR>
	<TR>
		<TD>B1</TD>
		<TD>B2</TD>
	</TR>
</TABLE>

And having a document:

<doc>
	<ele name1="A1" name2="A2" name3="A3"/>
	<ele name1="B1" name2="B2" name3="B3"/>
</doc>

processed through the same tyle sheet (foo.xsl) produces:

<TABLE>
	<TR>
		<TH>name1</TH>
		<TH>name2</TH>
		<TH>name3</TH>
	</TR>
	<TR>
		<TD>A1</TD>
		<TD>A2</TD>
		<TD>A3</TD>
	</TR>
	<TR>
		<TD>B1</TD>
		<TD>B2</TD>
		<TD>B3</TD>
	</TR>
</TABLE>
