I am trying to read a log file with the content look like this:
127.0.0.1 - - [17/OCT/2009:00:02:14 0000] GET xxxxxx xxxx xxx
I tried the following reg exp and I am getting ERROR: Unclosed group near index 90
regex = (d+.d+.d+.d+)s-s-s[(d+)/(w{3})/(d{4}):(d{2}):(d{2}):(d{2})s(d{4})].*
Can someone help me?
You forgot escaping some chars:
^(d+.d+.d+.d+)s-s-s[(d+)/(w{3})/(d{4}):(d{2}):(d{2}):(d{2})s(d{4})]
I think the "[" and "]" should be escaped: [[] and []] or [ and ].
For Java:
java.util.regex.Pattern.compile("(\d+.\d+.\d+.\d+)\s-\s-\s\[(\d+)/(\w{3})/(\d{4}):(\d{2}):(\d{2}):(\d{2})\s(\d{4})\].*")
First, escape [ and ] with backslahes. They have special meaning in regexps.
[ and ] are special characters. That s what it means by unclosed group. Depending on your flavor of regex, you ll need to put either 1 or 2 in front of each bracket.
regex = (d+.d+.d+.d+)s-s-s[(d+)/(w{3})/(d{4}):(d{2}):(d{2}):(d{2})s(d{4})].*
^d+.d+.d+.d+s-s-s[d{2}/[A-Z]{3}/d{4}:d{2}:d{2}:d{2}sd{4}]sGETs(.{6}s.{4}s.{3})$
