Regular expression for parsing name value pairs

by

  • No escape:

    /([^=,]*)=("[^"]*"|[^,"]*)/

  • Double quote escape for both key and value:

    /((?:"[^"]*"|[^=,])*)=((?:"[^"]*"|[^=,])*)/

key=value,"key with "" in it"="value with "" in it",key=value" "with" "spaces

  • Backslash string escape:

    /([^=,]*)=("(?:\\.|[^"\\]+)*"|[^,"]*)/

key=value,key="value",key="val\"ue"

  • Full backslash escape:

    /((?:\\.|[^=,]+)*)=("(?:\\.|[^"\\]+)*"|(?:\\.|[^,"\\]+)*)/

key=value,key="value",key="val\"ue",ke\,y=val\,ue

Edit: Added escaping alternatives.

Edit2: Added another escaping alternative.

You would have to clean up the keys/values by removing any escape-characters and surrounding quotes.
