So the Arduino has a hard time extracting the time for the full feed, so in order to expedite this process it is worthwhile to set up a .php document on your website to get just that information. For example, what it looks like for the BART API to get the next train departing Hayward, CA going North:

<p>$xml=simplexml_load_file("http://api.bart.gov/api/etd.aspx?cmd=etd&orig=HAYW&key=MW9S-E7SL-26DU-VV8V&dir=n");<br> echo '<'.$xml->station[0]->etd[0]->estimate[0]->minutes.'>';</p>

This will then put the time between '<' and '>' so we can tell the Arduino to just grab that number and use it.

Make sure to add the opening and closing PHP tags!
