[xsl] build a counter variable

[henry human <henry_human@xxxxxxxx>]

Hi 
 
I have an XSLT structure as bellow. I tried to build a counter with the
position () function .But it does not work because the position () function
ever begins with  1 in a loop. 
(In node1, node2, node3 the position begins
with 1 (position= 1)) 
 
 
<xsl:for-each select="node1/m"> 
<m><xsl:value-of
select="position()"/>  </m>   <== position should be 1
.......
<xsl:for-each
select="node1/node2/a">
 <a>....</a>                                             <== position = 2
 <a>....</a>                                               <== position = 3
 <a>.....</a>                                           <== position = 4
 </xsl:for-each>
 
<xsl:for-each select="node1/node3/f1"> 
 
 <f1><xsl:value-of
select="position()"/></f1>                                   <== position = 5
</xsl:for-each>
 
</xsl:for-each> 
 
 
 
Thanks for any help
