What would be the regular expression to extract 1944 from the following line :
vol. 9, no. 3, pp. 185-197, 1944
1944 is basically the year of Publication that i am trying to extract. I varies between 1900 and 2010.
If it is always the last part in the string, them you may use
$do indicate that, and the year shall always be a 4 digit number, so for that you used{4}.Hence, the regex you want shall be :
\d{4}$And if you ever want to test your regex, there is a pretty neat tool here : http://pagecolumn.com/tool/pregtest.htm , it also has the rules stated on the right side. 🙂
