I'm trying to parse a line of html as follows: <td style="width:20%" align="left">101.120:( KPA (-)</td> <td style="width:35%" align="left">Snow on Ground)0 </td>
however, sometimes it looks like this: <td style="width:20%" align="left">N/A</td> <td style="width:35%" align="left">Snow on Ground)0 </td> I want to get either the numerical value 101.120 (which could be a different number depending on the data that's been fed into the page, or in terms of the second option, 'N/A'. The regexp I'm using is: .*?Pressure.*?"left">(?P<baro>\d+?|N/A)</td>|\sKPA.*?Snow\son\sGround Can someone help me debug this. It's not picking up the number, and I'm not sure I've got the syntax for '|' right, but can't find a detailed tutorial on how to use |. Any help would be appreciated.
