This is a classic grouping problem (www.jenitennison.com/xslt/grouping) in which the grouping key is the most recent CHANGE element, calculated as above. In XSLT 2.0 <xsl:for-each-group select="log" group-by="((.|preceding-sibling::log)/change)[last()]"/> > > 3) Calcuate the time difference in seconds (<time> value is > also provide in > seconds) between the <useraction>Start</useraction> and the > <useraction>Stop</useraction> of the "mode A". > I'll pass on that one, got to be off to Mass.
