Parsing an html line and pulling out only numbers that meet a certain criteria

[Cory Mottice]

I am using line.rfind to parse a particular line of html code. For example, 
this is the line of html code I am parsing:

<strong class="temp">79<span>&deg;</span></strong><span 
class="low"><span>Lo</span> 56<span>&deg;</span></span>

and this is the code I use to split the line to (in this case) pull out the 
'79'.

position0 = line.rfind('{}'.format(date1.strftime("%a")))
if position0 > 0 :
        self.high0 = lines[line_number + 4].split('<span>')[0].split('">')[-1]

Now I need to only pull out that number if it is >=94 and <=37. If it does not 
meet this criteria, I don't want anything to happen. Any ideas? Thank you in 
advance!
