[SOLVED] need help with exception in regex

[haaglin]

Hi.

 

I have this expression to find any emails in a document:

 

$reg = '([[:alnum:]_\.\-]+)(\@[[:alnum:]\.\-]+\.+)([[:alnum:]\.\-]+)';
while( eregi($reg, $content, $regs ) ) {		
       //do some stuff with te found address in $content.
}

 

This works fine, but i want it to find all emails except those inside input tags (and only input tags) , like this one:

<input type="text" value="name@domain.com"/>

 

How do i do that?

You can do so with this method, or change your expression to PCRE and use lookarounds, e.g., (?<!=").

How do i convert it to PCRE?

 

I tried this, and it didn't work..

$reg =  '/(?<!=")([[:alnum:]_\.\-]+)(\@[[:alnum:]\.\-]+\.+)([[:alnum:]\.\-]+)/';
while( eregi($reg, $content, $regs ) ) {		
       //do some stuff with te found address in $content.
}

Almost got it i think, but it still returns the emails, except for the first letter.

 

$reg = '/(?<!=")(([[:alnum:]_\.\-]+)(\@[[:alnum:]\.\-]+\.+)([[:alnum:]\.\-]+))/';
while( preg_match($reg, $content, $regs ) ) {		
       //do some stuff with te found address in $content.
}

Solved it. This it what i did:

 

$reg = '/([[:alnum:]_\.\-]+)(\@[[:alnum:]\.\-]+\.+)([[:alnum:]\.\-]+)/';
preg_match ($reg, $content, $regs );
$mail = $regs[0];
while( preg_match ("/(?<!value=\")$mail/", $content, $regs ) ) {		
        $content =  preg_replace("/(?<!value=\")$mail/", $replace, $content );
preg_match ($reg, $content, $regs );
$mail = $regs[0];
}
