Как я могу поместить результат вычисления с xsl в новый элемент

Я использую xsl для расчета совокупного итога по элементу «Базис-продукт».Наконец, выходные данные должны быть помещены в тот же xml, после "Итоговых значений" в некоторых новых элементах, таких как: 

<Totals>
 <Totalproduct>
    <Basisproduct>110</Basisproduct>
    <Cumul_Amount>1,52</CustInvoice_LineAmount>
  </Totalproduct>
 <Totalproduct>
    <Basisproduct>198</Basisproduct>
    <Cumul_Amount>294,77</CustInvoice_LineAmount>
  </Totalproduct>
 <Totalproduct>
    <Basisproduct>992</Basisproduct>
    <Cumul_Amount>163,32</CustInvoice_LineAmount>
  </Totalproduct>
 <Totalproduct>
    <Basisproduct>993</Basisproduct>
    <Cumul_Amount>193,78</CustInvoice_LineAmount>
  </Totalproduct>
<Totals>

<-----I have this xml as an input.------>

xsl, который я использую для вычисления кумулятивной суммы "Basisproduct": 

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">              <xsl:output indent="yes"/>       <xsl:strip-space elements="*"/>

Это преобразование группирует элементы по Basisproduct и вычисляет общую сумму каждой группы. Обратите внимание, что он включает identity.xsl хорошо известную Преобразование идентичности .

[XSLT 1.0] 

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:include href="identity.xsl"/>

    <xsl:key name="KType" match="BodyCustInvoice" use="Basisproduct"/>

    <xsl:template match="Totals">
        <Totals>
            <xsl:apply-templates select="
                preceding-sibling::ConditionalArea[1]/BodyCustInvoice
                [generate-id() 
                = generate-id(key  ('KType', Basisproduct)[1])]" mode="totals"/>
        </Totals>
    </xsl:template>

    <xsl:template match="BodyCustInvoice" mode="totals">
        <Totalproduct>
            <Basisproduct><xsl:value-of select="Basisproduct"/></Basisproduct>
            <Cumul_Amount>  
                <xsl:value-of select="
                    sum(key('KType',Basisproduct)/CustInvoice_LineAmount)"/>
            </Cumul_Amount>
        </Totalproduct>
    </xsl:template>

</xsl:stylesheet>

выход:

Редактировать: Обновлен мой XSLT, чтобы учесть запрос OP на вставку итогов в исходный XML. Хитрость в решении проблемы состоит в том, чтобы использовать шаблон идентификации и глобальную переменную.

Если вы используете этот XSLT: 

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:key name="KType" match="Basisproduct" use="."/>
    <xsl:output indent="yes"/>
    <xsl:strip-space elements="*"/>

    <!-- create a variable w/ the calculated totals -->
    <xsl:variable name="CalculatedTotals">
        <xsl:for-each select="*/*/*/Basisproduct [generate-id() = generate-id(key  ('KType', .)[1])]">
            <xsl:element name="TotalProduct">
                <xsl:element name="Basisproduct">
                    <xsl:value-of select= "."/>
                </xsl:element>
                <xsl:element name="Cumul_Amount">
                    <xsl:value-of select= "/*/*/*[Basisproduct = current()][last()]/CustInvoice_LineAmount + sum(/*/*/*[Basisproduct = current()][last()]/preceding-sibling::*/CustInvoice_LineAmount)"/>
                </xsl:element>
            </xsl:element>
        </xsl:for-each>
    </xsl:variable>

    <!-- identity -->
    <xsl:template match="node()|@*">
        <xsl:copy>
            <xsl:apply-templates select="node()|@*"/>
        </xsl:copy>
    </xsl:template>

    <!-- root -->
    <xsl:template match="/">
        <xsl:apply-templates select="node()|@*"/>
    </xsl:template>    

    <xsl:template match="Totals">
        <xsl:copy>
            <!-- insert the calculated totals -->
            <xsl:copy-of select="$CalculatedTotals"/>
        </xsl:copy>
    </xsl:template>
</xsl:stylesheet>

Вы получите этот вывод XML:

Что вам нужно сделать, это использовать преобразование идентичности, а затем просто переопределить элемент Totals.

РЕДАКТИРОВАТЬ: Основываясь на комментарии ОП в ответе @ james.garriss, я изменил расчет, чтобы просто суммировать все.
