It implements a custom document parser + that determines which request is being parsed and uses the + corresponding parser implementation. The document parser + intentionally does not support the deposit request to show + how to handle unknown documents. The driver first constructs + a parser instance from all the individual parsers found in + protocol-pimpl.hxx. In then invokes this parser instance to + parse the input file and produce the in-memory object model. + Finally, it prints the contents of the object model to STDERR. + +To run the example on the sample XML request documents simply +execute: + +$ ./driver balance.xml +$ ./driver withdraw.xml +$ ./driver deposit.xml |
