sed to extract only floating point numbers from HTML
Hi All,
I'm trying to extract some floating point numbers from within some HTML code like this:
I've got the following sed but it strips out the spaces and decimal points - how can I modify this command so that I get a space (or any other delimiter) between each and maintain the decimal point?
sed 's/[^0-9]*//g' test.html
Many thanks,
p.

hmm, because these numbers appear more than once per line I'm thinking that sed isn't up to the job - will have a look for another method...

Parse::DebControl::Patch(3pm) User Contributed Perl Documentation Parse::DebControl::Patch(3pm)NAME
Parse::DebControl::Patch - Easy OO parsing of debian patch file metadata (DEP3) data
SYNOPSIS
use Parse::DebControl::Patch
$parser = new Parse::DebControl::Patch;
$data = $parser->parse_mem($control_data, $options);
$data = $parser->parse_file('./debian/control', $options);
$data = $parser->parse_web($url, $options);
DESCRIPTION
The patch-file metadata specification (DEP3) diverts from the normal debian/control
rules primarly of the "free-form" field specification. To handle this we most create
an parser specifically for this format and hardcode these rules direclty into the code.
As we will always only have one block of data, we will return the hashref directly
instead of enclosing it into an array.
The field B<Forwarded> is magic and will always exists in the out data, even if not specified
in the indata. It can only have three values, I<yes>, I<no>, and I<not-needed>. If not specified
it will have the value I<yes>.
