fetching variables from text

The format of Perl is very confusing.

I have the script to get the variables 'username1' and 'password1' from a text file with the following format:

'<b>Username: username1</b> and <b>Password: password1</b>'

Using the script (snippet):

($username) = $page =~ /<b>Username:\s(.*?)<\/b>/i;
($password) = $page =~ /<b>Password:\s(.*?)<\/b>/i;


How do I format this script to get the variables 'username1' and 'password1' from text formatted in this way?  (I've tried everything I can think of):

'Username: </b>username1&nbsp;&nbsp;&nbsp;
<b>Password:</b> password1<br>'

***Note that there is a space between 'Username"' and '</b>' and also a space between '</b>' and 'password1'

The formatting of the script is very confusing.  What do all the backslashes and (\s)'s mean?  Could someone help me to understand the way this is formatted?  Thanks.

Tim

For:
Username: </b>username1&nbsp;&nbsp;&nbsp;
<b>Password:</b> password1<br>

Try this:
($username) = $page =~ /Username:\s{0,}<\/b>\s{0,}(.*?)\&/i;
($password) = $page =~ /<b>Password:\s{0,}<\/b>\s{0,}(.*?)<br>/i;

Now, what does this mean. In the first line you search for the string "Username:" followed by 0 or more whitespaces "\s{0,}". Then must follow "</b>" which is written as "<\/b>" because only at the end "/" may appear. Then you look again for 0 or more whitespaces. Finally you look for the password "(.*?)". "." means any character "*" means any number of characters and "?" means minimum matching. All three characters are enclosed with "()" to tell the program to store the value in $username. Minimum matching means that username will be taken to the first "&" character. If "?" was omitted the username would be taken to the last "&" character. The matching for password is almost identical.
