I'm creating my own ELK dashboard to monitor my finances.
I got completely wiped out this year, a combination of many things, but most likely just poor fiscal responsibility.
Anyway;
I'm a regex newb, and I'm having a hard time with this.
Is there a way to quickly match strings with many trailing and leading whitespaces?
Here are my characters:
Account: ************0000 Purchase Amount: $10.00 Transaction Date: November 10, 2022 Transaction Description: UBER *TRIP HELP.UBER.C
Here's what I am trying in regexr.com
(?<account>(?<=Account:)(.*)(?=\s*Pur))
And my results contain a lot of whitespaces:
************0000
I'd like to have all the transaction $KEY:$VALUE pairs as named captures for grok filtering my bank transactions.
The results should be:
(?<account>($StackOverFlowSuperChargedRegex)
**************0000
Here is my regxr.com workspace link: regexr.com/736tg
EDIT: I am applying this grok pattern to an elastic search ingest pipeline, but I am not opposed to using it for a logstash ingest.
EDIT 2: @Paulo
Here is the content field after applying trim and gsub (without the dissect processor applied)

Not using Grok, but I feel It may help
