## Challenge #4: Date Parsing

Gave regex a workout

Hi, everyone. Just posted my solution.

Then I went to look at the solution provided, and Google decided to block the download: ....yxmd may be dangerous, so Chrome has blocked it".

I've downloaded dozens of these and this is the first time this has happened. Anyone else have the experience?

Solution for Challenge #4

Hi I was thinking the same as you but I found Designer acting strangely... did you find the same? Is it a bug? or am I misunderstanding how RegEx works... please help me understand.

This is what I ended up using:

.*(\d{2}-[[:alpha:]]+-\d{2,4}).*|.*(\d-[[:alpha:]]+-\d{2,4}).*|.*([[:alpha:]]{3}\s\d{2},\s\d{4}).*|.*([[:alpha:]]{3}\s\d{1,2}\s\d{4}).*

Because it didn't parse  properly when I used this at the beginning

.*(\d{1,2}-[[:alpha:]]+-\d{2,4}).*

Also didn't know how to handle the variation where there was a comma and space after the day of month and no comma just a space...  So I just repeated most of the pattern and made another variation.

I would lose the first character of the date each time... is it trying to minimize what is matched?  If yes, is there a better way to write this without so much overlap?

This was good learning... I wasn't familiar with RegEx.  My solution used multiple run of the DateTime tool to keep things simple vs formula that might need troubleshooting if things go awry.

Pretty sure not the best solution out there. Couldn't figure out the regular expression in one single line so used multiple regular expression and came up with a solution. Any constructive criticism is very appreciated.

My RegEx capability is almost non-existent. So I took the first tool in the solution to get the dates out. But otherwise used my own solution for the rest of it.

Had some fun with RegEx on this one and was able to get my parsing down to (A|B).
