Increase number in for-each iterations

support

I have a workflow that synchronizes documents. I have the initial document number. How should I model it so that in every iteration of the for-each block the number is increased by 1?

One of the possibilities is to handle it by a work queue.

I have used a different solution - in a transformation of data used for the for-each block I add a virtual field to the main element and fill it with position(). This attribute value is then added up to the initial document number in each iteration.

<xsl:template match="ROOT">
	<ROOT>
		<xsl:apply-templates select="Customer"/>
	</ROOT>
</xsl:template>

<xsl:template match="Customer">
	<xsl:copy>
		<xsl:copy-of select="@*"/>
		<xsl:attribute name="Position"><xsl:value-of select="position()"/></xsl:attribute>
	</xsl:copy>
</xsl:template>
