XSQL and basic flow control

Question

Hello again,
Is there any mean to execute more that one time the same XSQL action-element, like this (future XSQL version?):
<xsql:for-each test="{@selectedITEMS}">
<xsql:dml>
DELETE FROM ITEMS
WHERE ItemID = {.}
</xsql:dml>
</xsql:for-each>
Yes the duty can still be transferred outside XSQL, in the form of a DB proc or a custom action-element, but if some form of basic flow control exists/ed here inside XSQL, this would certainly come in handy!
Thanks

Answer 1

A simple way to do this would be to write an action handler that processes the value of the "selectedITEMS" parameter and sets a page-private parameter to the equivalent value with commas between them, then do:
<xsql:dml>
delete from items
where ItemId IN ({@ListOfLitems})
</xsql:dml>
then you do it all in one trip to the database.
