Get count of a for loop

austinf · May 16th, 2006, 02:41 AM

hi i would like to get the count of a for loop outside the loop

here is a sample code

Code:

<xsl:for-each select="Car">
 <xsl:variable name="level" select="position()"/>        
</xsl:call-template>

i would like the number of cars to be stored in a hidden variable on my jsp page. here i can include the hidden field inside the loop with last() called but that will repeat the hidden field the number of times the Car tag is present.

can some one tell me how to acccess the total from outside the for loop

thanks

I don't understand all the stuff about hidden variables on jsp pages, but you can count the number of Car elements before entering the for-each with the XPath expression select="count(Car)".
