Hi,

Thank you Vyacheslav.

That is a solution.

Shouldn't it be part of the standard and shouldn't it also be available for the mode parameter/attribute of <apply-templates/>?

Is that part of proposed changes for XSLT v2.1?

Thanks.

Cheers,
ac

Hi,

Is there, or shouldn't there be, a way to invoke templates dynamically as
in:

<xsl:apply-templates mode="$mode"/> or
<xsl:call-template name="$name"/>

rather than :
<xsl:choose>
  <xsl:when test="$mode eq 'mode1'"><xsl:apply-templates mode="mode1"/>
  <xsl:when test="$mode eq 'mode2'"><xsl:apply-templates mode="mode2"/>
  <xsl:when test="$mode eq 'mode3'"><xsl:apply-templates mode="mode3"/>
  ...
</xsl:choose>
or
<xsl:choose>
  <xsl:when test="$mode eq 'mode1'"><xsl:call-template name="name1"/>
  <xsl:when test="$mode eq 'mode2'"><xsl:call-template name="name2"/>
  <xsl:when test="$mode eq 'mode3'"><xsl:call-template name="name3"/>
  ...
</xsl:choose>

as the <xsl:choose/> seems clumsy, verbose, repetitive, error-prone, and
counter productive,
especially when also passing invocation parameters (<xsl:with-param .../>) ?

A sample use case may be letting a user select in which mode she wishes to
run a process, payroll for example, in trial, debug, report, post, archive,
or purge modes.

Thanks,
ac
