Question

I am trying to find the best regular expression pattern to extract a sub string from a string.

The string is of the type,

0816606366.Univ.of.Minnesota.Pr.Minnesota.Messenia.Expedition.Reconstructing.a.Bronze.Age.Regional.Environment.Jun.1972.pdf

I would like to create a regex that would give me everything after the first period. So in this case, the required sub string would be,

Univ.of.Minnesota.Pr.Minnesota.Messenia.Expedition.Reconstructing.a.Bronze.Age.Regional.Environment.Jun.1972.pdf

I tried

• \w+
• \w*
• [\w]*

and everything else in between but Im just not able to get the result I want. Could someone please point me in the right direction?

Thank you

edit: My apologies. I forgot to mention the programming language I was using. I am using Python and the re module that it comes with.

Answer 1

\d+\.(.+)

and replacement is

$1

Documentation is:

• \d match a digit
• \d+ match more than one digit
• \d+\. followed by a “.”
• \d+\..+ followed by anything
• \d+\.(.+) capture the “anything” chunk

i tested it at RegEx Planet:

Regular Expression: \d+\.(.+)
Replacement: $1
Test String#1: 0816606366.Univ.of.Minnesota.Pr.Minnesota.Messenia.Expedition.Reconstructing.a.Bronze.Age.Regional.Environment.Jun.1972.pdf

Result: Univ.of.Minnesota.Pr.Minnesota.Messenia.Expedition.Reconstructing.a.Bronze.Age.Regional.Environment.Jun.1972.pdf
