Re: sum of price * qty, without node-set()

Using FXSL one would simply write:


<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:foldl-func="foldl-func"
exclude-result-prefixes="foldl-func"
>
   <xsl:import href="foldl.xsl"/>

   <!-- This transformation must be applied to:
        numList.xml
     -->
   <xsl:variable name="vFoldrFun" select="document('')/*/foldl-func:*[1]"/>
    <xsl:output  encoding="UTF-8" omit-xml-declaration="yes"/>

    <xsl:template match="/">

      <xsl:call-template name="foldl">
        <xsl:with-param name="pFunc" select="$vFoldrFun"/>
        <xsl:with-param name="pList" select="/*/RECEIPT"/>
        <xsl:with-param name="pA0" select="0"/>
      </xsl:call-template>
    </xsl:template>

    <foldl-func:foldl-func/>
    <xsl:template match="foldl-func:*">
         <xsl:param name="arg1" select="0"/>
         <xsl:param name="arg2" select="0"/>

         <xsl:value-of select="$arg1 + $arg2/qtyRcpt * $arg2/line/pr"/>
    </xsl:template>

</xsl:stylesheet>

When this transformation is applied on your source.xml:

<BATCH>
  <RECEIPT>
    <qtyRcpt>1</qtyRcpt>
    <line>
      <pr>102.00</pr>
    </line>
  </RECEIPT>
  <RECEIPT>
    <qtyRcpt>3</qtyRcpt>
    <line>
      <pr>20.00</pr>
    </line>
  </RECEIPT>
</BATCH>

the wanted result is produced:

162
