Thanks! Works like a charm!
I am the very lowest of newbies when it comes to regex
and working through your solutions has been very
educational. I have one question about something I
couldn't figure out:
#(.*)#Uie
`.*?`sie
What is the purpose of the back-ticks and the '#'?
PCRE patterns has to be enclosed, you can use all the non alpha numerics
characters to do that. Personnaly, I prefer back ticks because I don't
have to escape it often inside my patterns.
For my example, you can also remove the ``s pattern modifier, It makes
the dot ( . ) accept any New line characters, and I had not see that
you removed them before.
What are 'Uie' and 'sie'?
there are patterns modifiers, you can find a complete list and
descriptions here :

Thanks again!

You could try something like:
$return = preg_replace('#(.*)#Uie',
'str_replace("
/>", "", "$1")');

Sorry,
Here is the code I am using to match the tags:
.*
I think this mask is better :
`.*?`sie
I have removed all the NL and CR chars from the
string
I am matching to make things easier. Also, I have
run
tidy on the code so the tags are all uniform.
The above string seems to match the tag well now,
but
I still need to remove the br tags from the tag
contents (.*).
To remove the tags, you need to call
preg_replace_callback() :
$str = 'hi .. bla bla
.. ...';
function cbk_br($match) {
return '' . str_replace('',
'', $match[2]) .
'';
}
$return =
preg_replace_callback('`(.*?)`si',
'cbk_br',
$str);
echo $return;
?>
The strings I will be matching are html formatted
text. Sample tags with content are below:
Ex-Secretary Mickey Mouse Loses Mass.
Primary
Ex-Secretary Mickey Mouse Loses Mass.
Primary Wins New Jersey
Ex-Secretary Reich Loses Mass. Primary
Again, any help is appreciated.
Kathleen
