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!

Hi Henry,
Without seeing your source and how your $myString is
formed, this is
rather hard to answer. Nor have you told us what
XSLT version you have.
In XSLT 1.0, dissecting a string is done using a
recursive template
("saving" to a variable is not possible in XSLT). In
XSLT 2.0,
dissecting a string is much easier, i.e. by using
tokenize(), replace()
or xsl:analyze-string. Some XSLT 1.0 processors
however allow the use
of the EXSLT extensions, see http://exslt.org for
how to use them.
Note that XSLT is a declarative language which makes
"traditional"
approaches (while loop, assigning to a variable) not
possible. If the
string you've put into $myString comes from nodes
(elements, attributes
etc), it is probably easier to construct the output
you want during the
process, instead of after the $myString construction
(in fact,
constructing how the output should look like is all
you do with XSLT, in
general).
Cheers,

Hi
I will to build a loop (for-each or while, etc)
I have a long string saved in a variable
myString:
myString= foo ffd : ppp ttt foo : 3mmm foo
In this sample there are three substrings
separated
by a colon token
How could it be done, looking over the myString
in a
loop and f. i.
save the substring in a variable named buf1
until
all three substrings
has been read ?
I will be very glad for any hint
Regards
Henry
