[REBOL] Parse question

From: semseddinm:bircom at: 19-Mar-2010 14:20

Hi, how do I extract just valid items or skip invalid ones using parse:

blk: [1 "a" 2 "b"] ;there are 2 valid values
>> parse blk [some [integer! string! (print "ok")]]
ok
ok

>> blk: [1 "a" 1.2.3 2 "b"] ;there is an invalid item 1.2.3
>> parse blk [some [integer! string! (print "ok")]]
ok
== false

How do I say, take the valid ones, just like in regular expressions?
