Help with a Regex query

[Kyllom Han]

Hi there!

I’ve understand that I can do multiple search&replace queries in this way:

Search: (á)|(é)|(í)|(ó)|(ú)
Replace: (?1Á)(?2É)(?3Í)(?4Ó)(?5Ú)

Example:

Before: árbol ácido
After: Árbol ácido

But how can I use this method if I need to add a precondition, such as line start and some punctuation before it?

I’ve tried:

Search: (^[—¿¡«]*?)[(á)|(é)|(í)|(ó)|(ú)] => Works!
Replace: \1(?2Á)(?3É)(?4Í)(?5Ó)(?6Ú) => Doesn’t work…

Example:

Before: —¿árbol ácido?
After: —¿rbol ácido?

Any help?

Regards.

I answer to myself.

As Sebastias Proske told me, the solution is ‘to use a non-capturing group for mere grouping purpose, character class is the wrong tool here’.

Search: (^[—¿¡«]*?)(?:(á)|(é)|(í)|(ó)|(ú))
Replace: \1(?2Á)(?3É)(?4Í)(?5Ó)(?6Ú)

Example:

Before: —¿árbol ácido?
After: —¿Árbol ácido?

Regards!
