XMLMath 1.1-SNAPSHOT-3

Xmlmath project is an expression evaluation engine that takes xml files as input, evaluates the (often mathematical) problem and calculates the result.

Basic Expression StructureContents

An xmlmath expression consists of a tree of nested xml tags. Each tag reads the value of its child nodes, applies an operation to it and returns the result to its parent tag. This is illustrated below with the expression that calculates 1 + 1.

< add xmlns="http://xmlmath.org/1.0" >
< long value="1"/ >
< long value="1"/ >
< /add >

Note: Because the xmlmath expression parser validates the input files against the xmlschema, it is necessary to always include the proper xml namespace directive in the expressions root tag.
