ou may have come across the need to read textual input into a structured representation before. Consider interpreting your own domain-specific language (DSL), reading back marshaled data from the disk, turning XML into a typed representation, or simply reading a comma-separated file: When it comes to parsing you have a number of options. For many common parsing tasks (such as working with the various XML APIs, regular expressions, or string splitting for comma-separated files), .NET provides extensive library support, but once you start growing your input language you will need a uniform parsing approach that can handle your requirements.
