Expressions i.e. XML path language expressions, compiling method for e.g. microcomputer, involves constructing representation such that complied representation of relative expression has link to complied representation of context expression

摘要

The method involves determining whether a relative expression is an expression, whose evaluation depends on an evaluation of another expression. A context expression associated to the relative expression is obtained among previously processed expressions. A complied representation for the expression to be evaluated is constructed such that a complied representation of the relative expression comprises a link to a complied representation of the associated context expression. Independent claims are also included for the following: (1) a device for compiling expressions on a structured document (2) a device for evaluating expressions on a structured document (3) a computer program comprising instructions to perform a method for compiling expressions on a structured document (4) a computer program comprising instructions to evaluate expressions on a structured document (5) a representation complied by expressions, comprising a compiled expression.
