So count() was another problem (but showed the same result). To the code fragment you posted here: Look at the xsl:for-each: If I write (as you wrote): <xsl:for-each select=". | following-sibling::row[position() < 20]"> Than all the generated html come out of Xalan-j after processing all rows! That means after 100 seconds (using 0.5 seconds per row, having 200 rows) This is my point. If I write: <xsl:for-each select="."> Than I have only the first row of each subtable, BUT: I see the result IMMEDIATELY after processing only this piece of xml! So I see the first table (only row number 1) after 10 seconds, I see the second table (only row number 21) after additional 10 seconds and so on. Do you see my point?
