Hi Rod,

First of all, your regexp ^MeasurePM*([0-9.]+) requires that the HTML

input starts with MeasurePM, which is not the case. The ^ at the

beginning is the problem. It does not refer to the beginning of a line

but of the parsed input. That is all input minus the text that has

already been parsed before. In your case it is the complete reply from

the web server including the HTTP header "HTTP/1.0 ..." which a browser

does not show.

According to the PCRE documentation, you can use ^ to match the beginning of a

line (the gap between \n and the next char) by enabling multi-line mode: /(?m)^.../

I have not tested that yet.
