Default XSLT loop counting and breaking.

How can I do some simple loops in XSLT and make counter updates..
Heres what im' working on::

    <xsl:for-each select="events/event">
        <xsl:for-each select="dates/date">
            <xsl:variable name="firstDate" select="concat(substring($currentDate, 1,4),substring($currentDate, 6,2),substring($currentDate,9,2))"/>
            <xsl:variable name="secondDate" select="concat(substring(., 1,4),substring(., 6,2),substring(.,9,2))"/>
            <xsl:if test="$secondDate > $firstDate">
                <div class="event">
                    <div class="event_tout" id="event_tout4">
                        <script type="text/javascript">
                    <div class="event_content">
                        <div class="event_header">
                            <div id="dub_wars" class="event_title text_blue"><a href="http://www.dubwars.com/2007/index.htm" target="_blank"><xsl:value-of select="../title" /></a></div>
                            <div class="event_location text_grey_dark"><xsl:value-of select="../location" /></div>
                        <div class="event_date text_grey_dark"><xsl:value-of select="." /></div>
                        <div class="event_body">
                            This is the only car show where you can take your V-dub in a closed course and drift, spin and burnout to your heart's content. They call it Hooliganism, we call it some of the most fun you can have in a VW.
This line::
<div class="event_tout" id="event_tout4">
                        <script type="text/javascript">

I need to be updating the value of event_tout4, to count from 1-~

At the same time I need to be writing new image values in the pngpong.serverButton.. javascript..

See what i'm going for?
Thanks for any help..

xsl:for-each behaves rather like a loop, but it's best to think of it as processing all the values in parallel because then you won't be misled into thinking that anything you do when processing the first element can affect the second.

For a simple counter, just use the position() function. Its value is 1 for the first item, 2 for the second, and so on.
