Method and system for stylesheet-centric editing

An editor for enacting changes to a document containing a template-based program that transforms tree-structured data from a first tree-structured data into a second tree-structured data, said method comprising:

• a user interface to permit selection of a document containing said template-based program;
• model of said template-based program in said selected document constructed by parsing elements of said template-based program into a corresponding logical construct comprising a match condition and at least one generator, said match condition for determining whether an element in said first tree-structure data is to be processed by one or more of said at least one generator;
• and
• a display for representing said model to said user.

A signal-bearing medium tangibly embodying a program of machine-readable instructions executable by a digital processing apparatus to perform a method of enacting changes to a document containing a template-based program that transforms tree-structured data from a first tree-structured data into a second tree-structured data, said method comprising:

• providing an interface to permit selection of a document containing said template-based program;
• constructing a model of said template-based program in said selected document by parsing elements of said template-based program into a corresponding logical construct comprising a match condition and at least one generator, said match condition for determining whether an element in said first tree-structure data is to be processed by one or more of said at least one generator;
• and
• displaying a representation of said model to said user.
