Re: [xsl] Help to construct a loop

[Abel Braaksma <abel.online@xxxxxxxxx>]

Hi Henry,

Yes, it does make things clearer. I'm afraid I can't help you with BPEL 
as it has little to do with XSLT; it's a misunderstanding to think that 
<while>, <condition> and/or <assign> are XSLT instructions, because they 
are not. The confusion may come from the fact that BPEL relies quite 
heavily on XPath 1.0.

However, BPEL (I assume you mean WS-BPEL, mentioned here: 
http://docs.oasis-open.org/wsbpel/2.0/wsbpel-v2.0.html) has a method 
called doXslTransform which could, in a way, be used to do what you 
want. But I'm not certain if something like that is necessary (you don't 
wanna smash a mosquito with a sledgehammer do you?).

It's a pity there's no general public BPEL list (there are a couple for 
the specs and some implementations). So I'm afraid you'll have to get 
your info from the primer or the specs itself.

Sorry that I can't be of any more help,

Cheers,
-- Abel Braaksma
