Ohh, was simpler that I was trying to do incrementing a variable. 
Anyway, I have seen  some examples and some e-mails on the list 
regarding to how increment a variable and If I'm not wrong there is no 
possibility of incrementing inside a for-each loop, so sometimes you 
need to change the xsl code only to make this feature working.

I have seen that in XSLT 2.0 we have an incremental function but I'm a 
newbie even in XSLT 1.0 so do you recommend to use version 2.0 instead 
of 1.0? Does this version a lot of improvements against version 1.0?

Anyone have a good and very simple example, a link or something that 
explains this "problem"?

I need to have that the number of groups is 3.

    

which is the number of things selected by
    <xsl:for-each select="product[count(. | key('hotelname', name)[1]) = 1]">

so



    <xsl:variable name="grps" select="product[count(. | key('hotelname', name)[1]) = 1]">



no of groups is <xsl:value-of select="count($grps)"/>
   <xsl:each select="$grps">
   ....

or, if you only need the number withing the for-each you don't need to
count you can use last() like:


    <xsl:for-each select="product[count(. | key('hotelname', name)[1]) = 1]">
group <xsl:value-of select="position()"/> out of <xsl:value-of select="last()"/>
...
