Problem with string pattern replacement

[denhamd2]

Hi,

 

I'm trying to replace all instances of a HTML <span> tag with the class="eventname" with <strong> tags instead.

 

Currently:

<span class="eventname">Text here</span>

 

Desired:

<strong>Text here</strong>

 

Any ideas how I'd do this using the preg match function in PHP?

 

Thanks in advance!

something like this

 

<?php

$str = '<span class="eventname" id="test">Text here</span><br /> <span>test one</span>';

echo preg_replace('#<span[^>]*class="eventname"[^>]*>(.*?)</span>#', "<b>$1</b>", $str);

?>

Personally I'd go with

$output = preg_replace('%<span[^>]+\bclass="eventname"[^>]*>(.*?)</span>%s', '<strong>$1</strong>', $input);

Or

 

preg_replace('~<span\b[^>]+\bclass\s?=\s?([\'"])eventname\1[^>]*>(.*?)</span>~is', '<strong>$2</strong>', $input)

Or

 

echo preg_replace(
'@(?P<mouse>     <:3_}~~~     </mouse>P?)'.
'?\074(?P<tag>SP\x{61}(?x-i: n\b))[^>]+'.
'\b[Clsa]{5}(?<=(?=PAN*)[\w\h]{9})\s?'.
'=\s?([\047\042])eVeNtNaMe\g{-1}[^>'.
']*>(?#\K)((?s:.*?))</(?P=tag)>@i',
'<strong>$4</strong>',
$str
);

That's so straight forward, why didn't I think of that?

Or

 

echo preg_replace(
'@(?P<mouse>     <:3_}~~~     </mouse>P?)'.
'?\074(?P<tag>SP\x{61}(?x-i: n\b))[^>]+'.
'\b[Clsa]{5}(?<=(?=PAN*)[\w\h]{9})\s?'.
'=\s?([\047\042])eVeNtNaMe\g{-1}[^>'.
']*>(?#\K)((?s:.*?))</(?P=tag)>@i',
'<strong>$4</strong>',
$str
);

 

And here salathe basically questions the readability of my patterns?!  lol

Salathe, put down the eggnog, you've had enough for one evening!

I hope your happy salathe, I thought I was beginning to get to grips with Regex, after seeing that pattern I have plummeted into a bout of depression.[/ot]

Sorry!

 

To be fair, it's really not all that complicated and certainly not the craziest regex I've ever written. The pattern is the same as presented previously in the thread only obfuscated with useless parts (like the mouse) or alternative representations (like the hex escape sequences, named back references).  If there's any part you'd like clarification on, I'm only a PM (or thread) away.
