A system and method that converts legacy and proprietary documents into extended mark-up language format which treats the conversion as transforming ordered trees of one schema and / or model into ordered trees of another schema and / or model. In embodiments, the tree transformers are coded using a learning method that decomposes the converting task into three components which include path re-labeling, structural composition and input tree traversal, each of which involves learning approaches. The transformation of an input tree into an output tree may involve labeling components in the input tree with valid labels or paths from a particular output schema, composing the labeled elements into the output tree with a valid structure, and finding such a traversal of the input tree that achieves the correct composition of the output tree and applies structural rules.

Enforcing a plurality of different policies on a stream of packets is disclosed. In lieu of running separate algorithms for each policy, the system exploits the commonalities of all of the policies. The conditions corresponding to the compiled rules are arranged in a condition tree and processed in a pipelined architecture that allows the results of the various stages to be carried forward into subsequent stages of processing. The rules for which all conditions have been satisfied can be identified by one stage of processing in one pass of condition tree traversal and are passed to subsequent stages. A rule table corresponding to an individual policy type can then be readily examined to determine partial or complete satisfaction of the rule of that policy type, without requiring a re-examination of the conditions underlying the rule. Additionally, corresponding actions can be taken where rule satisfaction is determined. This approach allows extremely high-speed policy enforcement performance.

The present invention discloses a data structure which, given an identifier for a Representational State Transfer (REST) resource, can rapidly yield a configured target and simultaneously yield all configured pattern based rules and constraints for the target. The disclosed data structure is a tree structure including nodes for URL portions. Each node is associated with a hash tree specifically grown in a manner that ensures collision occurrences are non-existent. The tree structure is effectively two or more superimposed trees; one for URL pattern matching to determine a target, another for determining constraints. A single tree traversal, which can be based on a progressive hash, can be used to concurrently determine a target and a set of constraints, which represents improved performance over conventional implementations that require multiple, distinct query / response operations to produce equivalent results.
