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,

Actually this is a bpel (business process execution
language) process which I am working on.
Bpel itself is xml based and allows using xsl
functions. For e. in the bpel specification 2.0 there
is possible to build loops with for-each, while etc.
In my case my bpel process becomes this string from a
web service and I will to handle this string within
the bpel process f.i. in a while loop.
As I mentioned in the sample the string which the bpel
process becomes from the web service has a colon which
I think enables to inspect the string based on the
token and build the substrings.
Unfortunately there is no a specific list or forum for
the bpel language specified issues.
<while name="lookForSubstrings">
<!this is what I dont know, how to build the
condition in xsl for a loop -->
<condition> substring-before($myString,
':') </condition>
<sequence name="sequence2">
<if name="extractSubstrings">
<assign name="SendOutputToClient"
...........
</assign>
<else>
<assign name="displayElse">
...........
I hope it makes the problem clearer!
