I
had a requirement where there was multiple for-loops and they wanted to
increment the sequence value in loop under the inner loop but counter should be
unique irrespective of the loop.
I
will take the example of ShipmentItem &ShipmentStop. So if there are 2 ShipmentItems
and 3 ShipmentStops then it should be incremented from 1 to 6. Since XSL
Doesn’t
support out-of-the box increment as it is not a programming logic,I had to look
for a work-around.
ShipmentItem
records will form the outer loop and ShipmentStop records the inner loop.
So
for using the increment logic I used count(preceding-sibling:: NODE) function .
I
am attaching the XSL code snippet for easier implementation and understanding.
$SEQ_COUNTER
variable will have the unique sequence ID.
<xsl:template match="/">
<top:testCollection>
<xsl:for-each select="/eboebo:UpdateShipmentEBM/eboebo:DataArea/eboebo:UpdateShipment/ns5:ShipmentItem">
<xsl:variable name="LOOP1_COUNTER">
<xsl:value-of select="count(preceding-sibling::ns5:ShipmentItem)"/>
</xsl:variable>
<xsl:variable name="COUNTER">
<xsl:value-of select="count(../ns5:Custom/ns6:ShipmentStop)"/>
</xsl:variable>
<xsl:for-each select="../ns5:Custom/ns6:ShipmentStop">
<!--looping logic for sequence ids -->
<xsl:variable name="LOOP2_COUNTER">
<xsl:value-of select="count(preceding-sibling::ns6:ShipmentStop)+1"/>
</xsl:variable>
<xsl:variable name="SEQ_COUNTER">
<xsl:choose>
<xsl:when test="$LOOP1_COUNTER='0'">
<xsl:value-of select="$LOOP2_COUNTER"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="($LOOP1_COUNTER*$COUNTER)+$LOOP2_COUNTER"/>
</xsl:otherwise>
</xsl:choose>
</xsl:variable>
<top:test1>
<top:ID_counter>
<xsl:value-of select="number($NN) +number($SEQ_COUNTER)"/>
</top:ID_counter>

<top:test1>

</xsl:for-each>
