This changes the code to use search() and indexOf() to find the boundaries of the relevant values, and substring() to extract them. This reduces the number of strings created on each invocation by 8x. The patch changes the behaviour if a key appears more than once. With the old code the last occurrence would be used. With the new code the first one is used. Hopefully this doesn't matter.
