Hi Dan,
Do you mean using two regex string like this:
regexStr1 = "<td><span>(.*?)</span></td>";
regexStr2 = "<td>(.*?)</td>";
And then run them using refindnocase()?
result1 = reFindNoCase( regexStr1, str, 1, "yes" );
result2 = reFindNoCase( regexStr2, str, 1, "yes" );
if( result1.pos[1] )
targetStr = mid( str, result1.pos[ 2 ], result1.len[ 2 ] );
else if ( result2.pos[1] )
targetStr = mid( str, result2.pos[ 2 ], result2.len[ 2 ] );
else
throw "Target string not found";
I also read that you can set an optional group in regex without triggering it as a back reference. It works by enclosing the optional group with (?: and )?. So I tried:
regexStr3 = "<td>(?:\<span\>)?(.*?)(?:\</span\>)?</td>"
When I tried this last week, I couldn't get it to work, but now it seems to work fine. Not sure what I did wrong.
Thanks!
