Noob Question about html

no one

Hi,

I want to write a pearl script that will go out to a web
site and download the page. Then pull certain value pairs
out of it. Basically I want to see graphs of snr etc.

Is grabbing the html possible in perl? I know the parsing
is. Basically I want to see if any of the values change and
it corresponds to cable outages.
example web page to parse

See the Perl FAQ entries "How do I fetch an HTML file?" and "How do I
remove HTML from a string?".

If you have Perl installed:

perldoc -q HTML

FYI: this newsgroup is defunct; use comp.lang.perl. misc in the future.

You could do it exactly the way it is described in the FAQ:
"How do I fetch an HTML file?"
I know the parsing is.

True, but I hope you intend to do it the right way and not by using some
"smart" use of REs? See FAQ
"How do I remove HTML from a string?"
for a few examples of why contrary to popular believe parsing HTML is not
trivial.
