Does any one have an idea is it possible to catch the block that has
no nested blocks of its type using regular expressions?
In other words how to catch
<blockbeginmark>.....-NO <blockbeginmark> until <blockendmark>

For instance, can
<div> ..... </div>
block can be caught with the condition it has no nested <div> blocks
in it?

Any ideas?

Regular Expressions are not really good for context aware matching and
parsing (which is what your match looks to be). For that, I would
recommend you do a little search on CPAN for HTML parsing modules such
as HTML:arser

Yes, use a html parser. There are many on CPAN and they work much better
that any regex you can come up with.
