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
