help counter recursive template

[Petterson Mikael]

Hi,

I call the sequenceNameStr ing template with:

<xsl:when test="child::*[name() = 'sequence']">
<xsl:call-template name="sequenceN ameString">
<xsl:with-param name="sequenceN ame" select="@name"/>
<xsl:with-param name="maxCount" select="sequenc e/maxLength"/>
<xsl:with-param name="value" select="0"/>
</xsl:call-template></xsl:when>

I can check that the parameter values are sent to the template.
However the incrementation of value does not happen.

I get the following only once( example):

eAgchCodes_name 0

but want:

eAgchCodes_name 0
eAgchCodes_name 1
eAgchCodes_name 2
.......

Any ideas why?

cheers,

Haven't examined it in detail, but I note one glitch: You aren't passing
maxCount down through the recursive call.

[Joe Kesselman]

Yep, that was it. (You're also not outputting line breaks between the
generated names, but I'll leave that as an exercise for the student.)
