Removing <html> tags from content in the YUI Editor

After integrating the YUI rich text editor, I am looking for a way to automatically remove the <html>, <body>, and DOCTYPE tags from the content when it is saved. Although I can achieve this by parsing the HTML code afterward, I am seeking a more efficient solution.

Currently, the edited text in the YUI editor is saved as:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
<html>
    <body>
        <p>foo</p>
    </body>
</html>

...but my goal is to save only the following:

<p>foo</p>

Any suggestions on how to achieve this?

P.S.: My implementation of the YUI editor involves using the yui_editor plugin for ruby on rails. However, I would appreciate a general answer applicable to any YUI editor as well!

I managed to find a solution to the issue on my own by parsing the HTML upon submission. Initially, I wasn't considering this approach, but ultimately realized it was the simplest way to resolve it. Leveraging the Nokogiri RubyGem for Rails, I performed the parsing:

value = Nokogiri::HTML(yui_content).css('body').to_html 
value.gsub!(/<body>/,'') 
value.gsub!(/<\/body>/,'')

A clever approach involves utilizing regular expressions to capture the text between <body> and </body>. For instance, consider this variant based on the YUI editor page:

var myEditor = new YAHOO.widget.Editor('content');
myEditor.render();

YAHOO.util.Event.on('clickbutton', 'click', function() {
    myEditor.saveHTML();

    //The variable html now stores the textarea content
    var html = myEditor.get('element').value, match;

    match = html.match(/<body[^>]*>([\s\S]*?)<\/body>/i);
    html = match ? match[1] : html;
});
