How to create 1 group to sum 4 elements with xslt - xslt

Question

I am trying to use muenchian to do a group/sum, but I can't make it work.
Any help available?! :)
XML I have:
<RLA760910>
<G_L_By_Object_Account___Localization_S10>
<Zsz_ObjectAcctSub_OSBOW_ID3>401100.900</Zsz_ObjectAcctSub_OSBOW_ID3>
<SumBegBalance>-20</SumBegBalance>
<SumDebitPeriod>10</SumDebitPeriod>
<SumCreditPeriod>-5</SumCreditPeriod>
<SumEndBalance>-15</SumEndBalance>
</G_L_By_Object_Account___Localization_S10>
<G_L_By_Object_Account___Localization_S10>
<Zsz_ObjectAcctSub_OSBOW_ID3>401100.900</Zsz_ObjectAcctSub_OSBOW_ID3>
<SumBegBalance>100</SumBegBalance>
<SumDebitPeriod>10</SumDebitPeriod>
<SumCreditPeriod>-5</SumCreditPeriod>
<SumEndBalance>105</SumEndBalance>
</G_L_By_Object_Account___Localization_S10>
<Zsz_ObjectAcctSub_OSBOW_ID3>411100.900</Zsz_ObjectAcctSub_OSBOW_ID3>
<SumBegBalance>-30</SumBegBalance>
<SumDebitPeriod>5</SumDebitPeriod>
<SumCreditPeriod>-10</SumCreditPeriod>
<SumEndBalance>-35</SumEndBalance>
</G_L_By_Object_Account___Localization_S10>
<Zsz_ObjectAcctSub_OSBOW_ID3>451100.900</Zsz_ObjectAcctSub_OSBOW_ID3>
<SumBegBalance>80</SumBegBalance>
<SumDebitPeriod>20</SumDebitPeriod>
<SumCreditPeriod>-10</SumCreditPeriod>
<SumEndBalance>90</SumEndBalance>
</G_L_By_Object_Account___Localization_S10>
</RLA760910>
I've so far:
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0"
<xsl:key name="AcctSub"
match="/RLA760910/G_L_By_Object_Account___Localization_S10"
use="#Zsz_ObjectAcctSub_OSBOW_ID3" />
<xsl:template match="Zsz_ObjectAcctSub_OSBOW_ID3">
<result>
<!-- Match the first acct element for a specific group -->
<xsl:apply-templates select="/RLA760910/G_L_By_Object_Account___Localization_S10/[generate-id() = generate-id(key('AcctSub', #Zsz_ObjectAcctSub_OSBOW_ID3)[1])]" />
</result>
</xsl:template>
<xsl:template match="/RLA760910/G_L_By_Object_Account___Localization_S10">
<total type="{#Zsz_ObjectAcctSub_OSBOW_ID3}">
<!-- Sum all the elements from the #type group -->
<xsl:value-of select="sum(key('AcctSub', #Zsz_ObjectAcctSub_OSBOW_ID3)/#Zsz_ObjectAcctSub_OSBOW_ID3)" />
</total>
</xsl:template>
</xsl:stylesheet>
Expected result will sum
SumBegBalance, SumDebitPeriod, SumCreditPeriod, SumEndBalance Group BY Zsz_ObjectAcctSub_OSBOW_ID3

Answer 1

Use the following script:
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" omit-xml-declaration="yes" indent="yes" />
<xsl:strip-space elements="*"/>
<xsl:key name="AcctSub"
match="G_L_By_Object_Account___Localization_S10"
use="Zsz_ObjectAcctSub_OSBOW_ID3"/>
<xsl:template match="RLA760910">
<xsl:copy>
<xsl:for-each select="*[generate-id()=generate-id(
key('AcctSub', Zsz_ObjectAcctSub_OSBOW_ID3)[1])]">
<result>
<xsl:variable name="Objects" select="key('AcctSub',
Zsz_ObjectAcctSub_OSBOW_ID3)"/>
<Zsz_ObjectAcctSub_OSBOW_ID3>
<xsl:value-of select="Zsz_ObjectAcctSub_OSBOW_ID3"/>
</Zsz_ObjectAcctSub_OSBOW_ID3>
<SumBegBalance>
<xsl:value-of select="sum($Objects/SumBegBalance)"/>
</SumBegBalance>
<SumDebitPeriod>
<xsl:value-of select="sum($Objects/SumDebitPeriod)"/>
</SumDebitPeriod>
<SumCreditPeriod>
<xsl:value-of select="sum($Objects/SumCreditPeriod)"/>
</SumCreditPeriod>
<SumEndBalance>
<xsl:value-of select="sum($Objects/SumEndBalance)"/>
</SumEndBalance>
</result>
</xsl:for-each>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
A few notes:
Zsz_ObjectAcctSub_OSBOW_ID3 is not an atribute but an element, so #
is not needed.
As the name of the root tag I used the same name as in your input.
Each result output tag contains Zsz_ObjectAcctSub_OSBOW_ID3 tag
(the grouping key) and sums of your 4 tags (within the group).

Answer 2

Try this as your starting point:
XSLT 1.0
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="utf-8" indent="yes"/>
<xsl:key name="grp" match="G_L_By_Object_Account___Localization_S10" use="Zsz_ObjectAcctSub_OSBOW_ID3" />
<xsl:template match="/RLA760910">
<result>
<xsl:for-each select="G_L_By_Object_Account___Localization_S10[generate-id() = generate-id(key('grp', Zsz_ObjectAcctSub_OSBOW_ID3)[1])]" >
<group type="{Zsz_ObjectAcctSub_OSBOW_ID3}">
<total-of-begbalance>
<xsl:value-of select="sum(key('grp', Zsz_ObjectAcctSub_OSBOW_ID3)/SumBegBalance)"/>
</total-of-begbalance>
<!-- add more totals here-->
</group>
</xsl:for-each>
</result>
</xsl:template>
</xsl:stylesheet>
When this is applied to the following well-formed example input:
XML
<RLA760910>
<G_L_By_Object_Account___Localization_S10>
<Zsz_ObjectAcctSub_OSBOW_ID3>401100.900</Zsz_ObjectAcctSub_OSBOW_ID3>
<SumBegBalance>-20</SumBegBalance>
<SumDebitPeriod>10</SumDebitPeriod>
<SumCreditPeriod>-5</SumCreditPeriod>
<SumEndBalance>-15</SumEndBalance>
</G_L_By_Object_Account___Localization_S10>
<G_L_By_Object_Account___Localization_S10>
<Zsz_ObjectAcctSub_OSBOW_ID3>401100.900</Zsz_ObjectAcctSub_OSBOW_ID3>
<SumBegBalance>100</SumBegBalance>
<SumDebitPeriod>10</SumDebitPeriod>
<SumCreditPeriod>-5</SumCreditPeriod>
<SumEndBalance>105</SumEndBalance>
</G_L_By_Object_Account___Localization_S10>
<G_L_By_Object_Account___Localization_S10>
<Zsz_ObjectAcctSub_OSBOW_ID3>411100.900</Zsz_ObjectAcctSub_OSBOW_ID3>
<SumBegBalance>-30</SumBegBalance>
<SumDebitPeriod>5</SumDebitPeriod>
<SumCreditPeriod>-10</SumCreditPeriod>
<SumEndBalance>-35</SumEndBalance>
</G_L_By_Object_Account___Localization_S10>
<G_L_By_Object_Account___Localization_S10>
<Zsz_ObjectAcctSub_OSBOW_ID3>451100.900</Zsz_ObjectAcctSub_OSBOW_ID3>
<SumBegBalance>80</SumBegBalance>
<SumDebitPeriod>20</SumDebitPeriod>
<SumCreditPeriod>-10</SumCreditPeriod>
<SumEndBalance>90</SumEndBalance>
</G_L_By_Object_Account___Localization_S10>
</RLA760910>
the result will be:
<?xml version="1.0" encoding="utf-8"?>
<result>
<group type="401100.900">
<total-of-begbalance>80</total-of-begbalance>
</group>
<group type="411100.900">
<total-of-begbalance>-30</total-of-begbalance>
</group>
<group type="451100.900">
<total-of-begbalance>80</total-of-begbalance>
</group>
</result>
Note that your expressions using #Zsz_ObjectAcctSub_OSBOW_ID3 fail because Zsz_ObjectAcctSub_OSBOW_ID3 is an element, not an attribute.
