Looks great - using the same construct as XSLT makes a lot of sense.
Just one comment though - the documentation page does indicate that the
<when> clauses are evaluated from top to bottom, but it took me three or
four readings to find it. Perhaps the order of evaluation needs to be
more conspicuous? And maybe an example to ram the point home ...
Since it's bad form to criticise without being willing to fix it, here
is one possible rephrasing:
The <choose> task executes only the tasks contained within the
first <when> element whose test expression is true.
If multiple <when> elements have true tests, only the tasks
contained by the first (in document order) are exectuted.
If no contained <when> clause tests true, tasks (if any)
contained
by the <otherwise> element are executed instead.
Examples
ii Demonstrate priority of <when> elements
<choose>
<when test="...">
</when>
<when test="true">
</when>
<when test="...">
</when>
</choose>
If the first <when> element is not executed, the second will
always be. The third
<when> clause will never be executed
Hmmm ... These don't read as well as what you already have. I'll have a
think and followup with some alternatives if I can come up with them.
Keep Smiling,
Bevan.
