I am creating a work-report sheet that needs to
know the value of working hours accrued to the
current date for each date. The xml looks like this
<Month name=â??Aprilâ??>
<Date day="1">
<Session task="LS Authorities">
<Notes hours-worked="2.00" notes="Documented changes from last week."/>
</Session>
</Date>
<Date day="2">
<Session task="LS Authorities">
<Notes hours-worked="2.00" notes="Worked
with Wayne resolving $2 border cases (see Campfire notes)."/>
<Notes hours-worked="1.50" notes="Final
boarder case resolution and 655/150 issue."/>
</Session>
</Date>
</Month>
I can get a Daily total of hours worked with a
named template called from the Sessions
template, but how can I show the hours accrued for all previous days?
For the XLM given, My output for the first Date
should be â??Daily Total: 2.0 Accrued: 2.0.â??
and for the second Date â??Daily Total: 3.5. Accrued: 5.5.â??
That is, I need to know the value of all
*previous* hours-worked and exclude any
*following* hours-worked. The XSLT so far look like this:
<xsl:template match="Session">
<fo:table-row>
<fo:table-cell>
<fo:block xsl:use-attribute-sets="subdiv1">
<xsl:value-of select="@task"/>
</fo:block>
</fo:table-cell>
</fo:table-row>
<xsl:apply-templates/>
<xsl:call-template name="day-total"/>
</xsl:template>
<xsl:template name="day-total">
<fo:table-row>
<fo:table-cell>
<fo:block xsl:use-attribute-sets="subdiv3">
<fo:wrapper xsl:use-attribute-sets="title">
<xsl:text>Daily Total: </xsl:text>
</fo:wrapper>
<xsl:value-of select="sum(Notes/@hours-worked)"/>
<fo:wrapper xsl:use-attribute-sets="title">
<xsl:text>Accrued: </xsl:text>
</fo:wrapper>
<!-- What goes here to select all previous Notes/@hours-worked???
<xsl:value-of select="sum(?????????????Notes/@hours-worked)"/>
Since your current node is <Session> you need to
address the Notes descendant of all preceding
siblings of the parent Date, plus the Notes child of the current node:
<xsl:value-of select="sum( (. |
../preceding-sibling::Date/Session)/Notes/@hours-worked)"/>
Note that if any of the attribute values might
possibly be the empty string, your sum() will be
affected and you can protect the sum in XSLT 1.0 by using a predicate:
<xsl:value-of select="sum( (. |
../preceding-sibling::Date/Session)/Notes/@hours-worked[number()=number()])"/>
In XSLT 2.0:
<xsl:value-of select="sum( (. |
../preceding-sibling::Date/Session)/Notes/@hours-worked[.
castable as xsd:double])"/>
</fo:block>
</fo:table-cell>
</fo:table-row>
</xsl:template>
I hope this helps.
