I have the below sentences. I need to split the sentences into multiple sentences if the sentence has dot or a matched word.
Sentence 1: There was an error while trying to serialize parameter http://uri.org/:Message . The InnerException message with data contract name 'enumStatus:' is not expected.
Expected result:
senetences = 1. There was an error while trying to serialize parameter http://uri.org/:vMessage.
2. The InnerException message with data contract name 'enumStatus:' is not expected.
Sentence 2: ORA-01756: quoted string not properly terminated ORA-06512: at module1, line 48 ORA-06512: at line 1
Expected result:
senetences = 1. ORA-01756: quoted string not properly terminated
2. ORA-06512: at module1, line 48
3. ORA-06512: at line 1
I am using below regex to split the sentences.
sentences = re.split(r'(?<=\w\.)\s|ORA-[0-9]{1,8}', input)
Issue here is, for the first case, if any word followed by dot is working fine. For the second case, I am able to split the sentence. I have 2 issues.
I need 3 sentences in this case.
Any help would be really appreciated.
You may use this regex for splitting:
\s+(?=ORA-\d+)|(?<=\.)\s+(?=[A-Z])
RegEx Details:
\\s+(?=ORA-\\d+)
: Match 1+ whitespace if that is followed by ORA-
and 1+ digits |
: OR (?<=\\.)\\s+(?=[AZ])
: Match 1+ whitespace if that is preceded by a dot and followed by an uppercase letter Code:
import re
arr = ["There was an error while trying to serialize parameter http://uri.org/:Message. The InnerException message with data contract name 'enumStatus:' is not expected.", "ORA-01756: quoted string not properly terminated ORA-06512: at module1, line 48 ORA-06512: at line 1"]
rx = re.compile(r'\s+(?=\bORA-\d+)|(?<=\.)\s+(?=[A-Z])')
for i in arr: print (rx.split(i))
Output:
['There was an error while trying to serialize parameter http://uri.org/:Message.', "The InnerException message with data contract name 'enumStatus:' is not expected."]
['ORA-01756: quoted string not properly terminated', 'ORA-06512: at module1, line 48', 'ORA-06512: at line 1']
(?<=\w\.)\s|(ORA-[0-9]{1,8})
You can try this and replace by \\n\\1
.
