Preg_match and Preg_replace trouble regular expressions Please HELP!

[stoppal]

need to extract all text between the following strings, but not
include the strings.
"<!-- #BeginEditable "Title name" -->"
"<p align="center"> #### </p>"
I am using preg_match(???? , $s, $results)
but I have had no success. I tried items like.. "<!-- #BeginEditable
"Title name" -->".*."<p align="center"> #### </p>"
But have had no luck.
Please any assistenc is appreciated.
In addition, I need to use preg_replace to replace the following:
<a href="/folder2/folder1/folder/*page.html">
with
<a href="site.com= page.php?option *=paper&itemid= page.html">
Again, any help is appreciated. The regular expressions confuse me, my

brain is about to explode from all the trouble shooting, I guess I'm
just not smart emough to figure it out.
PLEASE HELP!!
thanks

Try something like '/Title name" -->(.*)<p align="center/' for the
regex, and look for the answer in $results[1].

When you attempt to learn regexes, empty your mind of everything you
know from PHP or other computer languages. The parens, dot, star, and
other special characters are used in completely different ways than in
procedural languages.

Here's a quick link to PHP man:
http://us2.php.net/manual/en/function.preg-match.php

Here's a toot that others have found useful:

(myself, I learned regex back in the day of awk, when all we had was
woodburning computers)

In addition, I need to use preg_replace to replace the following:

Well, you'll probably want something along the lines of

$newString = preg_replace('/OldStuff/', "NewStuff", $oldString);

but check out a tutorial or two to get a handle on all this 'stuff'.

Friedl's _Mastering Regular Expressions_ is a good book on the subject.
It is not a light read. But then regular expressions are really a
computer language of their own, embedded into languages like PHP and
Perl, but with their own separate syntax and rules.

Yeah, been there. Wish you luck.

Thank you for the responses, I'm going to try this stuff tonight and I
hope it works.

thanks

Regular Expressions are great. Less than 10 lines of code can be so
powerful when you start to grasp the technology.
=============== =============
<?
$fp=fopen("preg test.txt","r+") ;
$content=fread( $fp,filesize("p regtest.txt"));
fclose($fp);

echo "\n\nBEFORE :\n------------------\n";
echo $content;

preg_match_all( "|<a href=\".+\">|m" ,$content,$matc hes);

foreach($matche s[0] as $value)
{
preg_match("|\" .+/([^/]+)\">$|",$value ,$page);
$pattern="(.+<!-- #BeginEditable \"Title name\" -->.+)" . $value .
"(.+<p align=\"center\ ">#### </p>.+)";
$replacement="< a href=\"site.com =page.php?optio n*=paper&itemid =" .
$page[1] . "\">";
$content=preg_r eplace("|$patte rn|s","\${1}" . $replacement .
"\${2}",$conten t);

}

echo "\n\nAFTER: \n------------------\n";
echo $content . "\n\n";
?>

HERE IS THE OUTPUT:
-------------------------------------------------

BEFORE:
------------------
some content that I don't want to edit...
<a href="/folder9/folder8/folder7/-page555.html">
<!-- #BeginEditable "Title name" -->
<a href="/folder2/folder1/folder/*page.html">
<a href="/folder9/folder8/folder7/-page555.html">
<p align="center"> #### </p>
More content that I don't want to edit...
<a href="/folder2/folder1/folder/*page.html">
AFTER:
------------------
some content that I don't want to edit...
<a href="/folder9/folder8/folder7/-page555.html">
<!-- #BeginEditable "Title name" -->
<a href="site.com= page.php?option *=paper&itemid= *page.html">
<a href="site.com= page.php?option *=paper&itemid=-page555.html">
<p align="center"> #### </p>
More content that I don't want to edit...
<a href="/folder2/folder1/folder/*page.html">

cameron7,

Thank you for your post. But I'm still having trouble. I think your
complicating what I'm trying to do. When I tried your code, nothing
appeared on the page. I assume, there is a syntax error, but I may be
wrong. I've tried debugging, with no luck. You included a loop
through for each apearance of the pattern, but in my pages it only
occurs once. Basically I'm removing an old header and footer, and
replacing old links with a new path from the existing page. I
appreciate you helping me.

thanks

Ok, I am getting closer but still no solution. I figured out your code
had extra spaces, most likely a google thing, but I removed them and
now I get the before part but the after section is blank. Any ideas?

thanks

Ok, sorry for all the extra posts, but I wanted to fill you in on where
I am.

When I use....

$fp=fopen("http ://www.site.com/pregtest.html", "r+") ;
$content=fread( $fp,filesize("h ttp://www.site.com/pregtest.html") );
fclose($fp);

etc. etc.

I get .....

"Before---------------After----------------", but that is it, no other
content.
If I change it to ...
$content=implod e('', file("http://www.site.com/pregtest.html") );
etc.etc..

I get .....

"Before---------------------
....ALL NORMAL CONTENT......"

But then nothing under After, nor do I see the "AFTER"

I am so lost I want to bang my head against a wall, I don't know much
programming and this stuff is way over my head.

thanks, any assistence is apprecaited.
