Regex #3

Open stedes opened 6 years ago

stedes commented 6 years ago

I think the regex expression is wrong.

TOKENS_ALPHANUMERIC = '[A-Za-z0-9]+(?=\s+)'

Doesn't this mean that you only consider tokens if they contain only alphanumeric characters and are followed by white space ?

Example: WORD1,WORD2, WORD3, WORD4 Word5

In the above sentence WORD4 and Word5 would be considered as tokens as the other words have a comma in them and as such are not valid tokens.

I think all the WORDS will be considered as tokens. The first four will be split on the comma, and the fifth will be split on the whitespace.
