When we loop on a set of nodes, the current context keeps changing and the position returns the number of the current context node in the loop. Please look at the following example -
================================================
XML file-
<source>
<child>one</child>
<child>Two</child>
<child>Three</child>
</source>
================================================
stylesheet -
<xsl:stylesheet version = '1.0'
xmlns:xsl='http://www.w3.org/1999/XSL/Transform'>
<!-- These are comments -->
<xsl:template match="/source">
<xsl:apply-templates select="child"/>
</xsl:template>
<xsl:template match="child">
<!-- position of the current context node -->
<xsl:value-of select="position()"/>
<xsl:text>.</xsl:text>
<!-- value of the current context node -->
<xsl:value-of select="."/>
<!-- This stuff is just for creating newline -->
<xsl:text>
</xsl:text>
</xsl:template>
</xsl:stylesheet>
================================================
Output -
<?xml version="1.0" encoding="UTF-8"?>
1.one
2.Two
3.Three
The numbers 1,2,3 above are generated by the position() function as the current context node kept changing by the call <xsl:apply-templates...>
Hope that this is clear.

Thanks Jaydev,
Now iam clear.
I have to ask u for one more clarification.
U guys discussed *[@*] in this post b4,but i couldnt understand the conclusion.I lost somewhere.
Could u plz explain me with an example like position().
Another request for everyone in this post is :
whenever u guys r discussing something plz post a conclusion at the end of that post.So that freshers like me can understand well.
After reading all those debates i actually forget what i read so far.
I would really appreciate ur reply.
