Help with regex on url

Does anyone know a good regex that will make these two changes to the same url?

a) add a folder name to the url
b) add .html at the end of the url

I will prefer to do this on the html code rather than on the fly. So from:

<a href="http://mydomain.com/url1">
<a href="http://mydomain.com/url2">
etc..

To

<a href="http://mydomain.com/folder/url1.html">
<a href="http://mydomain.com/folder/url2.html">
etc..

Many thanks.

 

Meh, I don't think you need to use a regular expression for a string so short. Seems to me It would over complicate things just a tad. If I where you I would just explode the string be / and then put it back together with the folder in the correct place.

Here check this out (it's rough but you get the idea):

<?
    function addFolder($url, $folder){
		$url = str_replace("http://", "", $url);
        $url = explode("/", $url);

        return "http://" . $url[0] . "/" . $folder . "/" . $url[1] . ".html";
    }
?>

PHP:

This of course takes for granted that the URL's will always be "url.com/url1". But the code can easily be modified to accommodate a different URL formatting.

you can use a regex like this:

$folder= "foldername";
$url = "http://google.com/search";
$new_url = preg_replace( "/^http:\/\/(.*?)\/(.*)$/" ,
                  "http://\$1$folder\$2.html",  $url);

PHP:

Hope that helps.
