You aren't in a loop, you are iterating over a set of nodes that you
have selected to process.

So, if you have the xml:

 <item/>
 <something_else/>
 <item/>
 <something_else/>

And you do xsl:for-each select="node" you will get a list of <item>
nodes to process:

  <item/>
  <item/>

You have 'pulled' two nodes to process.  You can find out which <item>
you are currently processing by using the position() function.  So if
you wanted to do something special to the first <item> node, you could
do:

  <xsl:for-each select="item">
    <xsl:if test="position() = 1"> do something special </xsl:if>
  </xsl:for-each>
