How to increment a value in xsl?

[Viswanathan Ramasamy]

hi all,

I want to increment a valu in xsl.
Code :

1 <xsl:variable name="uniqueID_Address1" select="'0'"/>
2 <xsl:for-each select="Z">
3 <xsl:if test="@n=$uniqueID">
4<xsl:value-of select="$uniqueID_Address1=$uniqueID_Address1+1"/>
5 </xsl:if>

I'm getting false in line no 4.

Viswanathan,

You can not change the variable value in XSL not like the other languages.

Try using recursion

XSLT is not a procedural language like Java, it is a functional language. And it has a lot of functions (courtesy of XPath) that allow you to write it that way. So something like:

<xsl:variable name="uniqueID_Address1" select="count(Z[@n=$uniqueID])"/>

is the replacement for those 5 lines.
