Hello good afternoon!!

I'm new to the world of regular expressions and would like some help creating the following expression!

I have a query that returns the following values:

caixa-pod
config-pod
consultas-pod
entregas-pod
monitoramento-pod
vendas-pod

I would like the results to be presented as follows:

caixa
config
consultas
entregas
monitoramento
vendas

In this case, it would exclude the word "-pod" from each value.

I would try (.*)-pod. It is not clear, where do you want to use that regexp (so regexp can be different). I guess it is dashboard variable.

You can try

\b[a-z]*(?=-pod)\b

This regex basically tells the regex engine to match

  • \b a word boundary
  • [a-z]* any number of lowercase characters in range a-z (feel free to extend to whatever is needed e.g. [a-zA-Z0-9] matches all alphanumeric characters)
  • (?=-pod) followed by -pod but exclude that from the result (positive lookahead)
  • \b another word boundary

\b matches a word boundary position between a word character and non-word character or position (start / end of string).
