html in xml

I have a problem. I have a not well formed html file and I want to insert it into a xml field. For example

    <h3>Hello world</h3>

When I parse the xml file I obtain an error because the parser don't find the <html> tag in my dtd. 
Is there a way to ignore html tags? Note: my html file isn't well formed! So I can't use a dtd for html tags.

My email is

Thank you in advance.
