I'm having a little trouble with recursion and could use some guidance
please.
My basic XML is this:
<Root>
<Child1>
<Dates>
<StartDate>..here is a date/time</StartDate>
<EndDate>..here is a date/time</EndDate>
</Dates>
</Child1>
<Child2>
....same type of children
</Child2>
...
...
...
I would like to basically get the duration between each StartDate and
EndDate, and get a total sum of those durations.
Here is my current code:
...
...
<xsl:call-template name="totalHours">
<xsl:with-param select="Dates/DateSpan/StartDate"
name="startDate"/>
<xsl:with-param select="Dates/DateSpan/EndDate" name="endDate"/>
</xsl:call-template> ... ...
<xsl:template name="totalHours">
<xsl:param name="startDate"/>
<xsl:param name="endDate"/>
<xsl:variable name="duration">
<xsl:call-template name="date:difference">
<xsl:with-param name="start"
select="$startDate"/>
<xsl:with-param name="end" select="$endDate"/>
</xsl:call-template>
</xsl:variable>
<xsl:choose>
<xsl:when test="$duration">
<xsl:variable name="recursive_result">
<xsl:call-template name="totalHours">
<xsl:with-param name="start" select="$startDate[position()
> 1]"/>
<xsl:with-param name="end"
select="$endDate[position() > 1]"/>
</xsl:call-template>
</xsl:variable>
<xsl:value-of select="date:add-duration(0 +
$recursive_result)"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="0"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
I'm currently getting an error saying that 'startDate should contain a
node-set'.
I appreciate any help.
