Abstract
Disclosed is a method of retrieving constant values. The method comprises compiling key-value pairs into a unified regular expression, evaluating the unified regular expression against a transformed input string to match a particular key and extracting the constant value associated with that particular key. The input string in transformed by linking different tags associated with each key-value pair in the unified regular expression into a single linked tag and linking the single linked tag to the input string. Additionally, the method provides for associating the constant value in each key-value pair with an un-fixed key (i.e., a unique regular expression) as opposed to a fixed key, so that different input strings can be matched to the same key.
