Parsing the Output

After sending a CGI request message for each page of the schedule for each bus, the Port Authority web server sends back the HTML for their results page:

My parser reads each incoming character and places it into a rotating buffer. Once the words "Forbes / Oakland" appear at the end of the buffer, the program checks a specific character location near the beginning of the buffer for the time. (This is a primitive and unreliable way to parse the data and will have be changed if the Port Authority changes the format of their output page... this should be improved with a new version of the code.)

The time is converted to military time for comparison of the current time.

This is done until the first time appears in the HTML file that's later than the current time.

This is the result for the bus line that's being checked.
