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:

Code:
<TR><TD class='awrc'>Parse CPU to Parse Elapsd %:</TD><TD ALIGN='right' class='awrc'>            64.50</TD><TD class='awrc'>% Non-Parse CPU:</TD><TD ALIGN='right' class='awrc'>            99.42</TD></TR>

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...
