    Hi Merryba,

    You can count the number of preceding-siblings:

    <xsl:value-of select="count(key('uniqueId', email)/preceding-sibling::*)" />

    But the key() has to return only one item - otherwise you can't trust the value you get; It may be the position() of the last one found or it could be any other, depending on the XSLT processor...

    Is there any way to check whether it is the first occurence or second occurence?

    Actually, can specify which one you want:

    <!-- First one: -->
<xsl:value-of select="count(key('uniqueId', email)[1]/preceding-sibling::*)" />

<!-- Last one: -->
<xsl:value-of select="count(key('uniqueId', email)[last()]/preceding-sibling::*)" />

    Hi Chriztian,

    Please let me know as how I can  get the count of siblings whose emailids start with the number 6 ?

    <!-- Last one: -->
    <xsl:value-ofselect="count(key('uniqueId', email)[last()]/preceding-sibling::*)"/>

    This doesn't help to know whether it is first occurence or last occurence of sibling of the key element

    Hi Merryba,

    Regarding the "start with the number 6" - there's a starts-with() function available for that, so you'd do something like this:

    <xsl:value-of select="count((preceding-sibling::* | following-sibling::*)[starts-with(email, '6')])" />

    About the first or last element - did you notice the predicates (square bracket stuff)? Adding [1] to an XPath selection will return only the first element - similarly, adding [last()] will return only the last element.

    PS: Could you maybe mark my first reply as the answer, so other people searching for similar problems can know there is an answer to that specific topic? Thanks.
