Hi Fatih,
Guessing (from your XSL snippet) how your input looks like:
<DocRoot>
<Documents>
<Document Doc_No="123">
<People>
<Person Person_Id="JB-007" Avg="1000"/>
<Person Person_Id="KL-008" Avg="800"/>
<Person Person_Id="JP-123" Avg="1400"/>
</People>
</Document>
<Document Doc_No="456">
<People>
<Person Person_Id="JB-007" Avg="200"/>
<Person Person_Id="KL-008" Avg="300"/>
</People>
</Document>
<Document Doc_No="789">
<People>
<Person Person_Id="JB-007" Avg="600"/>
<Person Person_Id="MT-111" Avg="500"/>
</People>
</Document>
</Documents>
</DocRoot>
and (still guessing) what exactly you want to achieve: totals and/or averages
by @Person_Id?
Seems like a typical case for Muenchian Grouping:
http://www.jenitennison.com/xslt/grouping/muenchian.html
With a key, you can access all the <Person> elements by their Person_Id
attribute:
<xsl:key name="persons" use="@Person_Id"
match="/DocRoot/Documents/Document/People/Person"/>
and then use this to generate a list of unique @Person_Id's with:
select="Person[count(. | key('persons', @Person_Id)[1]) = 1]"
Here's a stylesheet that calculates sums and averages from the input above:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="xml" version="1.0" indent="yes"/>
<xsl:key name="persons" use="@Person_Id"
match="/DocRoot/Documents/Document/People/Person"/>
<xsl:template match="/DocRoot/Documents">
<Result>
<People>
<xsl:apply-templates select="Document/People/Person[count(. |
key('persons', @Person_Id)[1]) = 1]">
<xsl:sort select="@Person_Id"/>
</xsl:apply-templates>
</People>
<Totals>
<xsl:variable name="num" select="count(Document/People/Person)"/>
<xsl:variable name="sum" select="sum(Document/People/Person/@Avg)"/>
<Num><xsl:value-of select="$num"/></Num>
<Sum><xsl:value-of select="$sum"/></Sum>
<Avg><xsl:value-of select="format-number($sum div $num, '#.##')"/></Avg>
</Totals>
</Result>
</xsl:template>
<xsl:template match="Person">
<Person Person_Id="{(_at_)Person_Id}">
<xsl:variable name="num" select="count(key('persons', @Person_Id))"/>
<xsl:variable name="sum" select="sum(key('persons', @Person_Id)/@Avg)"/>
<Num><xsl:value-of select="$num"/></Num>
<Sum><xsl:value-of select="$sum"/></Sum>
<Avg><xsl:value-of select="format-number($sum div $num, '#.##')"/></Avg>
</Person>
</xsl:template>
</xsl:stylesheet>
gives this output:
<Result>
<People>
<Person Person_Id="JB-007">
<Num>3</Num>
<Sum>1800</Sum>
<Avg>600</Avg>
</Person>
<Person Person_Id="JP-123">
<Num>1</Num>
<Sum>1400</Sum>
<Avg>1400</Avg>
</Person>
<Person Person_Id="KL-008">
<Num>2</Num>
<Sum>1100</Sum>
<Avg>550</Avg>
</Person>
<Person Person_Id="MT-111">
<Num>1</Num>
<Sum>500</Sum>
<Avg>500</Avg>
</Person>
</People>
<Totals>
<Num>7</Num>
<Sum>4800</Sum>
<Avg>685.71</Avg>
</Totals>
</Result>

Hi,
I am trying to get the sum of all values in a for-each
loop. Is it possible to store the partial sums to find
the final result?
xsl is something like this :
<xsl:for-each select
="Documents/Document[(_at_)Doc_No=$lastdoc]/People/Person">
<xsl:variable name="person" select="@Person_Id"/>
<xsl:variable name="week"
select="count(/DocRoot/Documents/Document/People/Person[(_at_)Person_Id=$person])"/>
<xsl:value-of select="format-number
(sum(/DocRoot/Documents/Document/People/Person[(_at_)Person_Id=$person]/@Avg)
div $week, '##.##')"/>
</xsl:for-each>
For the above xsl snippet what I am trying to do is to get the sum of all
"sum(/DocRoot/Documents/Document/People/Person[(_at_)Person_Id=$kisi]/@Avg)
div $week " values. I tried to write an XPath expression to find the sum
but
couldn't success. So I need to store the partial sums to find the result.
Any idea?
