Using XML as a common parser architecture to separate parser from compiler

A method for compiling queries, comprising the computer-implemented steps of:

• receiving a query that conforms to a first syntax of a plurality of syntaxes defined for a query language;
• determining whether said first syntax is a particular syntax of said plurality of syntaxes;
• if said first syntax is not said particular syntax, then converting said query into said particular syntax of said plurality of syntaxes defined for said query language;
• parsing said query that conforms to said particular syntax to generate parsed information;
• and
• compiling said query based on said parsed information, wherein said step of compiling is performed by a compiler that is capable of compiling only queries that conform to said particular syntax.

A database server that uses extensible Markup Language (XML) as common parser architecture, comprising:

• a XQueryX converter comprising a first logic that:
• receives a query that conforms to a first syntax defined for a XML Query Language;
• determines whether said first syntax is a XQueryX syntax defined for said XML Query Language;
• and
• if said first syntax is not said XQueryX syntax, then converts said query into said XQueryX syntax;
• a XML parser which is capable of parsing queries in said XQueryX syntax, wherein:
• said XML parser is communicatively coupled to said XQueryX converter;
• and
• said XML parser comprises a second logic that:
• receives said query in said XQueryX syntax, and passes said query to generate parsed information;
• and
• a XML compiler which is capable of compiling input that conforms to XML,
• wherein:
• said XML compiler is operatively coupled to said XML parser;
• and
• said XML compiler comprises a third logic that compiles said parsed information.
