A method (and system) for editing rules contained in a first document, where the rules define a transformation of data on a second document and where the first document and second document have elements constructed in a tree structure having nodes, each rule having a template structure including at least one match condition, the match condition being an expression in the template that describes a subset of tree nodes, includes selecting at least one rule in the first document and checking a match condition of the user-selected rule with the tree nodes from the second document to determine which structures in the second document match the selected rule.

Method and system for stylesheet rule creation, combination, and removal

A method (and structure) 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, including providing an interface to permit selection of a document containing the template-based program, constructing a model of the template-based program in the selected document by parsing elements of the template-based program into a corresponding logical construct having a match condition and at least one generator, where the match condition determines whether an element in the first tree-structure data is to be processed by one or more of the at least one generator, and displaying a representation of the model to the user.

Method and system for stylesheet-centric editing

Host communications software is modified to include user-provided transport code for sending and receiving datastreams to and from a host. A user transport code component is provided to the host communications software, and the user transport code component is dynamically linked to a datastream processing component of the host communications software. Dynamically linking a datastream processing component of the host communications software and the user transport code component includes defining transport events, and providing interfaces to listen and handle the transport events. Host access software can be redesigned into a collection of dynamically connectable and reusable, self-contained, functional components that software developers can use to generate host access applications.

A technique, system, and computer program for enabling workstation software applications to efficiently and reliably use legacy host application data streams, without requiring change to the host applications. This is achieved by defining attributes of presentation spaces (screens or parts of screens) that are of interest to the workstation application, defining target objects to process the legacy host data, registering these attribute definitions and corresponding target objects with a screen recognition object, using the screen recognition object to monitor the host data streams for occurrence of a registered screen, and generating an asynchronous event to invoke the target object when a registered screen is detected. The efficiency is obtained because the workstation application programmer no longer has to write code to monitor the host data streams for the screens of interest. The reliability is obtained because the application programmer now reliably knows when a screen of interest appears in the host data stream.
