Tim,
This is a very interesting test case because it shows that some elements
might contain multiple values separated by ";". It looks like CSV
contents within elements!
I don't think fn:tokenize is the right tool for this situation: it is
designed for returning strings not nodes to be bound to controls. It is
true that XSLTForms is using faked nodes for returning what can be seen
as a sequence but it is just a trick for an XPath 1.0 engine.
I have been thinking of a way for splitting the text node which is the
child of the element into many and, then, it would be possible to bind
them individually for editing. I am not sure that all DOM
implementations in browsers will support adjacent text nodes without
concatenate them. An XPath function should not modify nodes so a
specific action would be required...
It should be better, first, to consider that the element value has a
specific data type, which is a restriction of xsd:string. As for RTE,
the separator to be recognized can be associated to this data type.
Then, the input control bound to each element with this data type will
actually be rendered by XSLTForms with multiple HTML inputs, as many as
sub-values, and with buttons to add and remove inputs. This would be
developed as an XForms extension in XSLTForms.
What do you think?

Alain,
Thank you for your reply. Attached is a test case using fn:tokenize to
create input controls. The purpose is to edit library catalog records
for audiovisual material and transcribe information about production
credits.
Best regards,
Tim

Tim,
Currently, fn:tokenize() is returning faked text nodes. This is
good enough for xf:output and should also work with xf:setvalue.
It would still be easy to create standalone text nodes owned by
default instance to do the trick more appropriately for complex cases.
Could you please send me a test case?
Thanks!

Alain,
Can fn:tokenize be used to update instance data with xf:input, or
only to display data with xf:output? I have XML data with
elements that contain semicolon-delimited strings that I would
like to split across separate input controls, but I guess the
data can't be updated once it is tokenized?
Best wishes,
Tim
