Hello,

The easiest way would be to iterate through Pagelist1 and within the iterator, iterate through Pagelist2 to compare. Obviously, this doesn't scale, so if you have really large pagelists, you might want to get more creative. In that case, we can start asking questions like, will value of a1 be repeated, or if you find a match, can you remove the entire page from Pagelist2 from consideration? If so, you might be able to use things like page-remove to prune the list as you go. Assuming you don't need Pagelist2 later. That said, I'm not aware of any OOTB functionality to do this comparison for you, so one way or another I think you'll need to build it yourself.

Thanks,
Mike

You could use a data transform to iterate the first list

Within each iteration call OOTB @Default.IsInPropertyCollection().

An Integer Parameter can be used to count the number of times a match was found. EX:

    Set Param.Count   =   @Default.IsInPropertyCollection(.LookAtProp, .OtherPageList) ? Param.Count + 1 : Param.Count  

Thanks guys for your responses. Actually, I can't use an activity or datatransform as  I need to use this in a when rule as a visibility condition so I wanted to know if there is  any OOTB function to compare both the pagelist values.
