r - Problems in a regular expression to extract names using stringr -


i cannot understand why regular expression not work extract info want. have unlisted vector looks this: 

   text <- c("senator, 1.4balbal", "rule 46.1, declares",              "town, 24", "a town long name, 23", "this document,23)

i create regular expression extract name of "town", if town has long name 1 written in vector ("a town long name"). have tried extract name of town: 

   reg.town <- "[[:alpha:]](.+?)+,(.+?)\\d{2}"     towns<- unlist(str_extract_all(example, reg.prov))

but extract around ",".

thanks in advance,

it looks town name starts capital letter ([[:upper:]]), ends comma (or continues end of text if there no comma) ([^,]+) , should @ start of input text (^). corresponding regex in case be:

^[[:upper:]][^,]+
