The _problem_ is, that I need to calculate at the end of each week, the
total duration time of all the tasks for that week (week = duration time
of task 1 + duration time of task 2 + duration time of task 3...). I
have tried using the sum() function in different ways but did not
worked. I also tried creating a new tag inside my 'task' node, but it
just does not work, sum() keeps on appending the values instead of
summing them.
Sum is correct, for example:
sum(for $x in //task return $x/xs:dateTime(@end) - $x/xs:dateTime(@start))
returns
PT1M28S
This is how my .XSLT file looks like: http://pastebin.com/jLV2EHFa
and this is the result generated file: http://pastebin.com/dDpJVqLL
As you see, the results are appended and not summed, which is what I
need.
You are working at the <task> level, so you are outputting the sum of
just that 1 task. You need to operate at the week level, eg change
the for-each in:
<xsl:template match="year/week">
....
<xsl:for-each select="day/task">
<xsl:call-template name="total_duration"/>
</xsl:for-each>
to just:
<xsl:value-of select="sum(for $x in task return $x/xs:dateTime(@end) -
$x/xs:dateTime(@start))/>
(well, make it a variable and then do your formatting as you have done already)
