How to replace or remove the character?

I have some data with the following pattern:

“firstname \“fifa\” familyname”

now I like to replace the \" characters and everything between them.

That I get the following data pattern:

“firstname familyname”

I tried it with the String Manipulation node ( replace($composers$, “\ \” , " ") ) and with the String Replacer node ( Regex [\.?\] ). Even if these regular expressions are wrong, I still get error messages because the \ character in the KNIME nodes does not work like all other characters. It overrides the functions of the other characters.

What can I do?
