Achieving a nesting rule...?

Hi there, 

Im hoping someone out there can provide me with some insight into the
following...

I have an xml doc resembling something like......

<list ordinal="Process">
				<listitem>
					<para>Some Paragraph</para>
					<list>
						<listitem>
							<list>
								<listitem>
	
<para>some paragraph</para>
	
<table>
	
<tgroup>
	
<tbody>
	
<row>
	
<entry>
	
<para> table in list</para>
	
</entry>
	
<entry>
	
<para>table in list</para>
	
</entry>
	
</row>
	
<row>
	
<entry>
	
<para>table in list</para>
	
</entry>
	
<entry>
	
<para>table in list</para>
	
</entry>
	
</row>
	
</tbody>
	
</tgroup>
	
</table>
								</listitem>
							</list>
						</listitem>
					</list>
				</listitem>
				<listitem>
					<para>two process</para>
				</listitem>
			</list>


For each table, (from matching <tgroup>) I must assess the level of nesting
within the list and then assign a table width appropriately......eg
Example 1.

<list>
   <listitem>
	<table>
	     <tgroup>
This is 1st level nesting of the table and I wish the width to be 90%, my
xsl for that is similar to.....

	<xsl:when test="name(../../..)='list' or
name(../../..)='orderedList'">
		<xsl:attribute name="width">
		<xsl:text>90%</xsl:text>
		</xsl:attribute>
	</xsl:when>						

Example 2.

<list>
   <listitem>
      <list>
         <listitem>
	     <table>
	       <tgroup>
This is 2nd level nesting of the table and I wish the width to be 85%, my
xsl for that is similar to.....

	<xsl:when test="name(../../../../..)='list' or
name(../../../../..)='orderedList'">
		<xsl:attribute name="width">
		<xsl:text>85%</xsl:text>
		</xsl:attribute>
	</xsl:when>	

Ive carried on above onto the 3rd level of nesting (80%) but realise that
this isnt the best way as I am not catering for any deeper levels (4th
onwards).....is there a shortcut I can use to achieve this?	

You could say .... count each list/listItem pair and thats the level of
nesting required (1st, 2nd etc...)........?		


Kind Regards

Karen
