Regular expression for a single word

Problem with a regular expression...
Anyone know why this is happening: Filename: 031\_Lobby.jpg RegExp: (\d+)\_(.*)[^\_e|\_i]\.jpg Replacement: \1\_\2\_i.jpg That produces this: 031\_Lobb\_i.jpg For some reason it's chopping the last character from the second back- reference (the "y" in "Lobby". It doesn't do that when I remove the [^_e|_i] so I must b...

Any pitfalls with this regex that matches ampersands not already encoded
In PHP, I want to encode ampersands that have not already been encoded. I came up with this regex /&(?=[^a])/ It seems to work good so far, but seeing as how I'm not much of a regex expert, I am asking if any potential pitfalls can be seen in this regex?

Function Parser with RegEx in Python
I have a source code in Fortran (almost irrelevant) and I want to parse the function names and arguments. eg using (\w+)\([^\(\)]+\) with a(b(1 + 2 * 2), c(3,4)) I get the following: (as expected) b, 1 + 2 * 2 c, 3,4 where I would need a, b(1 + 2 * 2), c(3,4) b, 1 + 2 * 2 c, 3,4 Any suggestions?
