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:
#<h[1-9]>(.*)</h[1-9]>#Uie
`<h([1-6])>.*?</h\1)>`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! Kathleen

hi
M. Sokolewicz a écrit :
You could try something like: $return = preg_replace('#<h[1-9]>(.*)</h[1-9]>#Uie',
'str_replace("<br
/>", "", "$1")');

Sorry, Here is the code I am using to match the <h*> tags:
<h([1-9]){1}>.*</h([1-9]){1}>
I think this mask is better : `<h([1-6])>.*?</h\1)>`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 <br /> tags, you need to call preg_replace_callback() :
<?php
$str = '<h1>hi <br /> ..</h1> bla bla <h5> .... <br />
..</h5> ...<br />';
function cbk_br($match) {
return '<h' . $match[1] . '>' . str_replace('<br />',
'', $match[2]) . '</h' . $match[1] . '>';
}
$return =
preg_replace_callback('`<h([1-6])>(.*?)</h\1>`si',
'cbk_br', $str);
echo $return;
?>
The strings I will be matching are html formatted text. Sample <h*> tags with content are below:
<h4>Ex-Secretary Mickey Mouse <br />Loses Mass. Primary</h4>
<h4>Ex-Secretary Mickey Mouse <br />Loses Mass. Primary <br /> Wins New Jersey</h4>
<h4>Ex-Secretary Reich Loses Mass. Primary</h4>
Again, any help is appreciated. Kathleen
