When i try to use position() inside the for-loop, i get only one record.It should display nine records.I tried removing the position() code and it displays 9 records.


<xsl:for-each select="$distinctPrepackIndicatorUpcCode">
        <xsl:call-template name="printPrepackBox">
            <xsl:with-param name="prepackItem" select="VariableDataSet/VariableDataElement[@Code='750']/@Value" />
            <xsl:with-param name="prePackUpc" select="VariableDataSet/VariableDataElement[@Code='790']/@Value" />
            <xsl:with-param name="totalPacks" select="./@Case1Count" />
        </xsl:call-template>
        <table width="94%" cellpadding="0" cellspacing="0" class="prepack_line_item_table" border = "1">
            <xsl:call-template name="printPrepackLineItemHeader"/>
<xsl:choose>
  <xsl:when test="$prepackItemIndex &lt;= count(key('prepackIndicatorUpcCodeKey', concat(VariableDataSet/VariableDataElement[@Code = '750']/@Value, '-', VariableDataSet/VariableDataElement[@Code = '790']/@Value)))">
<xsl:for-each select="key('prepackIndicatorUpcCodeKey', concat(VariableDataSet/VariableDataElement[@Code = '750']/@Value, '-', VariableDataSet/VariableDataElement[@Code = '790']/@Value))">
<xsl:if test="position() = $prepackItemIndex">
                                <xsl:call-template name="printPrepackLineItemRow">
                                    <xsl:with-param name="itemNo" select="./@Style" />
                                    <xsl:with-param name="itemColor" select="./@Color" />
                                    <xsl:with-param name="itemSize" select="./@Size" />
                                    <xsl:with-param name="itemUpc" select="./@UPC" />
                                    <xsl:with-param name="itemMsrp" select="VariableDataSet/VariableDataElement[@Code='620']/@Value" />
                                    <xsl:with-param name="qtyPerPack" select="./@Case1ItemQuantity" />
                                    <xsl:with-param name="totalUnits" select="./@Case1Count * ./@Case1ItemQuantity" />
                                </xsl:call-template>

    </xsl:if>
</xsl:for-each>
</xsl:when>
</xsl:choose>
</table>
</xsl:for-each>

Well assuming that $prepackItemIndex is a number then position() appears to be working just fine - its only displaying the n'th record where $prepackItemIndex = n.

What where you expecting position() to do exactly?

Actually the count(key('prepackIndicatorUpcCodeKey', concat(VariableDataSet/VariableDataElement[@Code = '750']/@Value, '-', VariableDataSet/VariableDataElement[@Code = '790']/@Value)) returns 9 records.

I want to do a for-each on those 9 records and display to user in the report.$PrepackIndex will be 1 by default and i want to loop till 9.

Right - so remove the <xsl:if> then. I don't see what the problem is.

position() returns the current position in the for-each loop, i.e. for the first item it returns 1, for the second it return 2 etc. So if you put a <xsl:if> in there based on position() it will only output the one item where the position matches the value of $prepackItemIndex.

Thanks.I did not notice that checking.
