Hi there guys,

I'm new to these forums but basically I have a little query about regular expressions.

Basically I have a project where I load in a text file containing an unlimited length of comma separated list of strings where the last string doesn't have a comma at the end of it.

e.g.:
johnny,matinay,crazy,rampage,eastpak,ghghg

All I want to do is to create a regular expression that will ensure that there is a comma separated list of strings where in each string there are alphanumeric characters, the "&" sign and white space but NO commas inside the string (since that is what the list is split with), so if the above list was changed to "johnny,matinay,,rampage,eastpak,ghghg" where there is one comma straight after the other then the regular expression would pick this up and throw an error.

All I have so far is:
[^,]+[,].+

But i'm not sure where to go from there.

Thanks in advance guys!

[^,]+[,].+
