Ruby
1

Hi,

I have a line of HTML file like this

123.20

I want to remove all such HTML tags as ‘’ and only get the 123.20.

Would anyone kindly tell me how?

Thanks very much.

Your going to need to give some more information here. Using
javascript?
On the server side? Is it always that format?

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.

So server side… If you use the Hpricot Gem you can do this pretty
easy.

a = “123.20”
value = Hpricot( a ).innerText.strip
