Get text between curly braced placeholder tags

I need to extract subject/body of an email message generated by a form in Joomla. I am using some tags for defining different subjects/body for each language, like:

{lang en}English Text{/lang}
{lang it}Italian Text{/lang}
{lang fr}French Text{/lang}

I have the following code for striping Text from Subjects in different languages:

$msgSubject = $template->subject;           
if ($language == 'it-IT')
{
    preg_match('~{lang it}([^{]*){/lang}~i', $msgSubject, $match);
    $msgSubject = ($match[1]);
}
elseif ($language == 'en-GB')
{
    preg_match('~{lang en}([^{]*){/lang}~i', $msgSubject, $match);
    $msgSubject = ($match[1]);
}

and so on for other languages. It works perfectly for the subjects of the emails, which is just plain text. If I do the same on the Body, which is a string containing HTML elements like p and br, and so on, it doesn't work...

Code sample:

$msgBody = $template->body;

if ($language == 'it-IT')
{
    preg_match('~{lang it}([^{]*){/lang}~i', $msgBody, $match);
    $msgBody = ($match[1]);
}
elseif ($language == 'en-GB')
{
    preg_match('~{lang en}([^{]*){/lang}~i', $msgBody, $match);
    $msgBody = ($match[1]);
}

it simply outputs nothing. What should I change in the preg_match function to avoid mass with HTML tags?

Click on preg_match_all
Is this what you want? Works for me..

Edit: If you do like this:

You capture the language too and you don't need the ifs.
