This may not be possible at all. RegExes cannot match nesting pairs, 
i.e. if your <p></p> contains other <p></p> pairs then you have reached 
the end of what a RE is capable of. Also due to the way these tags are 
structured, you need at least negative lookahead for it, which also not 
all RE engines support.

If you do
<p.*</p>

then the RE would catch from the first <p to the last </p>, hence you 
need to specify the .* with a lookahead like (?!</p>), or use a 
non-greedy RE.

This may as well be the problem. Some RE engines treat newline 
characters as special, i.e. it may be that Kate matches only *within* a 
line.

In short - maybe a RE engine is simply not a good tool to do that. Then 
use an XML parser instead.
