A computer-implemented method of creating a schema specific parser for processing Extensible Markup Language (XML) documents can include receiving an XML schema comprising a plurality of components, determining a hierarchy of the plurality of components of the XML schema, and creating an execution plan specifying a hierarchy of XML processing instructions. Each XML processing instruction can be associated with an XML processing function of a virtual machine that performs an XML document processing task. The hierarchy of XML processing instructions can be determined according to the hierarchy of components of the XML schema. An instruction causing the virtual machine to invoke a de-serialization module that extracts at least one item of information from the XML document can be inserted into the execution plan. The execution plan can be compiled into a bytecode version of the execution plan that is interpretable by the virtual machine. The bytecode version of the execution plan can be output.
