An improved document processing system is provided by virtue of the present invention, wherein documents and processing associated with those documents are combined by structuring documents according to a common structure applicable to both the documents themselves and the processes that are applied to the documents. In one embodiment of a client-server document processing system in which the present invention is implemented, an agency is interposed between clients and servers, wherein the agency operates one or more agents which operate on documents which pass between the client and server. The agents are a set of active documents, where an active document is a structured document containing text and/or behavior. The active documents operate on a network in a context of strings, streams and parse trees, which allows programs to be embedded in documents, and since the documents are structured, the programs have the same syntax as documents. Furthermore, since documents are structured, their elements can be used as data structures.
