Field extraction from html email

I've been banging my head against the wall trying to get this to work, and not succeeding, obviously. I have a 217 line email from my power company I've ingested using the imap app, and I want to get a fields out of it. The built in field extractor will only show the first 15 lines of the email, so that's not helpful, and the regex's I've cobbled together aren't pulling out the data. The data that I want is:

 font face="Arial, Helvetica, sans-serif" size="2" color="" style="font-size: 13px">43 kWh </font

and I want the "43 kWh" from that line, and to name the field "previousday_energy_use".
and the next line I want is:

 font face="Arial, Helvetica, sans-serif" size="2" color="#3e3e3e" style="font-size: 13px">$5</font>

and I want the "$5" data.

I'd appreciate any help here.
If I do a

rex field=_raw "(?<kWh>13px\">.*?<)"   

the field created just shows

13px"><

Does this work for you?:

... | rex "13px\">(?P<previousday_energy_use>\d+\skWh)" | rex "13px\">(?P<cost>\$\d+)"

Yes thank you! That's it exactly. Forgot my slashes apparently.
