Hi,

I have a line of HTML file like this

<td><B><font color=006689>123.20</font></B></td>

I want to remove all such HTML tags as '<xxx>' and only get the 123.20.

Would anyone kindly tell me how?

Thanks very much.

Hi Daniel

I got this line from the body of NET::HTTP.post_form. I want to extract
the digital number embedded in this line. Actually ,I think I can do
this by remove all strings begin with "<" and end with ">". But I don't
know how to do.
