I am working on one task, to extract title tag from given normal text ( it's not a HTML DOM ). I have below cases where need to extract title tag(s) :

Case 1 :

<html>
<head>
           <title>Title of the document</title>
</head>
<body>
The content of the document......
</body>
</html>

Expected : Title of the document

Case 2 :

<html>
<head>
           <title>Title of the document</title>
           <title>Continuing title</title>
</head>
<body>
The content of the document......
</body>
</html>

Expected : Title of the document Continuing title

Case 3 (Nested title tags)

<html>
<head>
           <title>Title of the document
           <title>Continuing title</title></title>
</head>
<body>
The content of the document......
</body>
</html>

Expected : Title of the document Continuing title

I wanted to extract title tags using regular expression in javascript. Reg-ex should work for above case.

Is anyone knows about this..please let me know... Thanks in Advance
