Best way to code this, string to map conversion in Groovy

Question

I have a string like

def data = \"session=234567893egshdjchasd&userId=12345673456&timeOut=1800000\"

I want to convert it to a map

Answer 1

If you're looking for efficient, regular expressions are where it's at:

def data = "session=234567893egshdjchasd&userId=12345673456&timeOut=1800000"
def map = [:]
data.findAll(/([^&=]+)=([^&]+)/) { full, name, value ->  map[name] = value }

println map

prints:

[session:234567893egshdjchasd, userId:12345673456, timeOut:1800000]

If you're not familiar with regular expressions, it might look a little foreign, but it's really not that complicate. It just has two (groups), the first group is any character but a "&" or a "=". The second group is any character besides a "=". The capture groups are on either side of a "=".
