I am trying to get URLs out of logs in Splunk. I am getting an error.

my regex query is : xxx.xx.xxx.xxx|regex = (http(s)?:(\/\/)?(w{3}.)?[-a-zA-Z0-9@:%.+~#=]{2,256}(.[a-z]{2,256})?\b([-a-zA-Z0-9@:%+.~#?&\/\/=]*)

The x's are an IP that is also included in the search. I am not disclosing the IP. Sorry

The error is: Error in 'SearchParser': Missing a search command before '-'. Error at position '57' of search query 'search xxx.xx.xxx.xxx|regex = (http(s)?:(\/\/)?(w{...{snipped} {errorcontext = (w{3}.)?[-a-zA-Z0-9@}'.

HELP!!!! I don't understand the error!

When Splunk says "missing a search command before [some character]", it means the parser got to that character and didn't understand what came next. You could either paste the search into a text editor and manually find character #57, or you could just look for all such characters in your search and try to determine if any of them could be confusing the parser.

In this case, the issue is likely your regex's character set: [-a-zA-Z0-9...]. Even though it's supposed to be legal to lead off the character set with an unescaped hyphen, Splunk does not properly recognize it. You'll need to escape it with a backslash.

To extract a URL without querystring, try this regex. You have too many special chars that need to escaped. Eg: ? s/b \?

(http(s)?[^\?]+)

If you want to include the querystring, then try this

(http(s)?[^\s]+)
