help counter recursive template

[Petterson Mikael]

Hi,

I call the sequenceNameString template with:

<xsl:when test="child::*[name() = 'sequence']">
<xsl:call-template name="sequenceNameString">
<xsl:with-param name="sequenceName" select="@name"/>
<xsl:with-param name="maxCount" select="sequence/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_name0

but want:

eAgchCodes_name0
eAgchCodes_name1
eAgchCodes_name2
.......

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.

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.)

<!-- The real bug was that you forgot to pass both
