parsing code with regular expression

Question

I have a text/code like this:

fsa sda ${kpp dsa } } sadf ${44} sda } fd sda  sd fdas ${ads}

I would like to build a regular expression that would find all occurrences of ${soemthing}. From the code above, the matches would be:

${kpp dsa } }, ${44} sda }, ${ads}

What I have managed to come up with is this regex "\$\s*{.*?}+", but that one unfortunately doesn't do do trick and I can't think of anything that would. Could you please help me?

Answer 1

You are describing a non-regular language, yet you are attempting to use regular expressions. It is best to create a parser for this!

Also, to answer you main problem: the { and } characters have a different meaning in regular expression, you should escape them with a backslash
