I'm only a Perl beginner and I know there are lots and lots of pages out there that deal with searching through arrays, but I cannot find anything relevant to my problem.

I have two arrays and I want to find if one of the arrays is contained within the other (with the order preserved). Moreover I want to then be able to delete the contents of one array from the other

 @bigarray qw(this is the main array from which to delete elements)

 @smallarray qw(delete elements)

An array such as  @other qw(elements delete) should not match against @bigarray.

I need to somehow remove "delete elements" from @bigarray. I have tried using nested loops, trying to keep track of indexs so I can use splice, but I just can't figure out how to do it properly with loops

@bigarray will probably be <1K in size and this delete action will only be called perhaps once or twice during my script, so efficiency is not an issue.

Any help appreciated :-)

Just for clarity, the exact sequence from @smallarray should be removed from @bigarray i.e.

 @bigarray qw(delete this is elements the main array from which to delete elements)

should be transformed to

 @bigarray qw(delete this is elements the main array from which to)

Thanks!
