The HTML / XML tree synchronization module synchronizes a document with a view or multiple views, after a change has been made to the document. First, the tree synchronization module receives a document change from an application program. An update processor converts the tree data of the document to a character string, and receives document change information from one or more application program interfaces. The update processor utilizes the document change information to update the document tree data character string. The document change information is then sent to one or more application program interfaces to determine the scope and content of the document views. A log generator receives the view change information, and creates record logs for each changed document view. These logs are played by a log player to each view, and each view data tree is updated with the view changes contained in the change logs. The tree synchronization module sends the subsequent view changes to the application program to update the display views.
