As long as it's as simple as this, you could count the total number of
items, divide by 50 and 'ceiling' the result to get the number of pages.
If your 'item' elements were all within a 'list', for example:

<xsl:template match="list">
  Number of pages: <xsl:value-of select="ceiling(count(item) div 50)" />
</xsl:template>

The XML document doesn't have to be parsed twice, but you might have to
process the output of your page-creating stylesheet with a page-numbering
stylesheet (say) if you can't work out the number of pages that there are
going to be a priori from the original XML document that you have.  If your
algorithm for creating pages is fairly simple, as above, then you there's
no need.

I hope that helps,
