meta tags

Hi All

Is there any API which fetches expires and other meta tag value from the HTML file itself and
not from the HTTP header provided by web server
as in <meta http-equiv="expires" content="0">

there are some API's like HTAnchor_expires(pParentAnchor)
but these fetches the value from HTTP header of web server
and I want them directly from my HTML file


Thanks
Kamal
