is it possible to select multiple rows in xforms:repeat

Hi
Is it possible to do a multiple selection on rows generated by a repeat structure and then delete those rows with a single click of a delete button?

Right now, I have a single delete button and the row I select can be deleted by clicking on this delete button.

thanks in advance

this is possible, but requires some additional work. I suppose you can't
use the index() function to do this, because there can be only one
*current* item in a repeat that can be addressed using this function.
(if i'm interpreting the XForms specs correctly). So i fear you will
have to manage the selected items and the mechanism to iterate over
those items to delete them yourself.

I think there are two ways to manage the selection: either one writes
the selection state into the data instance itself, or in a external
"control" instance. To finally execute a "multi-delete", one could use
the exforms:iterate (xxforms:iterate) attribute [1] to iterate over the
selected items (i suppose this function is available only in OF 3.7).
This may be easier to implement with a "control instance" than by adding
the selection information to the data instance.

If the xxforms:iterate attribute isn't available (in pre-3.7 versions, i
think), the deletion could be done by a XSLT. Here, it would be easier
to habe the selection data embedded in the data instance, so this
instance can be passed by a submission to a XPL with replace="instance"
that will itself call the XSLT.
