Abstract: A method includes parsing at least one text source document to construct a document node tree such that the document node tree includes location information indicating a location of text within the at least one text source document corresponding to each node of the document node tree, and wherein the document node tree includes source identification information that identifies a source document for at least one node in the document node tree. The source identification information is added to the at least one text source document, thereby forming at least one instrumented text source document. A live web page is generated with a browser based on the at least one instrumented text source document.

Abstract: A method includes providing a Web development tool for developing an application that includes a primary document and a plurality of related files. A user interface for controlling the Web development tool is generated. The method includes generating as part of the user interface a code editor panel, wherein the code editor panel includes a primary editor sub-panel for editing content of the primary document and a secondary editor sub-panel for editing content of the related files.

Abstract: A remote authoring service is described. Remote page authoring includes receiving a stream of data from a server that includes embedded control attribute data. The embedded control attribute data facilitates the generation of a proxy control and allows a web page designer to make modifications to dynamic elements of the webpage without requiring the executable code for the actual controls. The proxy control may provide preview data of the control to allow the client to perform authoring functions using the proxy control. Modifications made via the proxy control service may then be transmitted to the server where the controls are updated.
