Change value of Variable

[saqi]

Hello,
I've a situation in which i have to count the number of transactions/records, retrieved from my XML document, on one page. I have to show that number at the end of each page, with this I've to also show the total number of records in one document. I figure it will be solved by using variables but still can't find the way to solve this issue, as variables can only be defined once and it cannot be accessed outside the boundary in which it is defined. Is there any possible way supported by XSLT?
Thanks for your Help!
Regards,

If you are using <xsl:for-each select=""/> to iterate your records then you can use position() function to get the record number.
e.g.
 <xsl:for-each select="$Employees/Employee">
        <xsl:variable name="iCount" select="position()" />
...........Do Something...........
</xsl:for-each>

Hello sonika_nitj,
Thanks for your reply. I have already tried that. now the situation is that if my data overflows from one page to 2nd and then to 3rd and so on, in this case i want to show the count,how many records on one page occured, at the end of each page.how can i do this?
i hope you got my point.
thanks

You can't do this.

1. There is no feedback from the page layout (formatter) software to the XSLT.
2. 'Variables' in xsl-fo are immutable. Think of them as constants that you set.

You need to think of your problem in a different way.

We added some extra table-marker support in FO 1.1, e.g. so that you can
show a subtotal of values on a page; you could probably use this
mechanism, depending on whether your formatter supports FO 1.1.
E.g. give each record a value of "1" but show only the total of
those values on each page.

Maybe someone else on this list can tell me if this might work ;-)

It appears similar to the example in the spec at
http://www.w3.org/TR/xsl11/#d0e14681 so it should work if the records
can be formatted in a table.
