The regular expression you seek is: [^"]*

so if you want to change all these:

<a class="wildcat" href="lion.html">
<a class="wildcat" href="tiger.html">
<a class="wildcat" href="leopard.html">

to:

<a class="wildcat" href="bigcat.html">

you search for:

<a class="wildcat" href="[^"]*">

and replace with:

<a class="wildcat" href="bigcat.html">

(make sure you tick the match case & regular expressions + seclect 'source code')

var baz = "foo";

var filter = new RegExp(baz + "d")

"food fight".match(filter);

// returns ["food"]

[a-zA-Z]{2}[0-9]{2}[a-zA-Z0-9]{4}[0-9]{7}([a-zA-Z0-9]?){0,16}

([a-zA-Z]{4}[a-zA-Z]{2}[a-zA-Z0-9]{2}([a-zA-Z0-9]{3})?)

preg_match('/<div id=["]{0,1}ad_content["]{0,1}>(.*?)</div>/s', $content['content_body'], $matches);
$content['content_body'] = $matches[1];

/(w|[_.-])+@((w|-)+.)+w{2,4}+/
