Replace String using regular expressions

Question

Replacement with Regular expressions in Java - I have a String

    allof{
    condition {licenseState=="NY"}
    condition{professionId==301}
    condition  {professionId=="301"}
}

would be it's possible to do a replacement in java using regex so the string looks like this one:


    allof{
    condition 'licenseState=="NY"', {licenseState=="NY"}
    condition 'professionId==301', {professionId==301}
    condition 'professionId=="301"', {professionId=="301"}
    }

basically getting what inside the {} brackets and putting it separately. Is it possible and how? NewLine char is not guaranteed to be present after each condition.

I've tried:

condition\s*?{[a-zA-Z0-9=<>\s"']*}

I have tried code condition\s*?{[a-zA-Z0-9=<>\s"']*} code which selected everything, but I don't know how to extract inner part of it — eugened

Here is a site that you can use to test out your regex: regexplanet.com/advanced/java/index.html Go there an try your regex — Lee Meador

@eugened this is a very simple case for group reference. do some google, do some test. next time you met it again, you know how to handle. e.g. this could let u start : {([^}]*) — Kent

You can use the string replaceAll function. Something like this:

yourString.replaceAll("\\{([^{}]*\\=\\=[^{}]*)\\}", "'$1', {$1}");

Assuming no nested {}

str = str.replaceAll( "(?<=condition)\\s*(\\{([^}]+)\\})", " '$2', $1" );
