Peter,

I don't know what you mean by "calls the other template on a particular order" (maybe typo for "in a particular order"?), but it may still be possible to do as Jeni says, since you can bind the result of a template call to a variable and interrogate it, as in:

<xsl:variable name="general-result">
  <xsl:call-template name="general"/>
</xsl:variable>

...then depending on what general-result is, you can do one thing or another (as well as copying it to the output).

This is all wonderfully vague: maybe seeing a concrete example would help? It's surprising how often straight conditionals can be avoided in XSLT by the smart use of templates ... as in

<xsl:apply-templates select="child[$condition1]" mode="condition1"/>
<xsl:apply-templates select="child[$condition2]" mode="condition2"/>

... and such like. Which seems to be in line with what you're asking.

Cheers,
Wendell

This is not possible I think, since the general template calls the other
template on a particular order (based on the calculation in the general
template), so I don't think it's possible in this situation.

Thanks for the tip,

Peter

Just a thought, but depending on what the general template is doing,
it might be that you can turn around the processing, so that instead
of calling the general template with a parameter specifying the mode,
you apply templates in the specific mode and those templates call the
general template as appropriate to perform the necessary calculations.

Cheers,

Jeni
