Patching Base Document Object Model (DOM) with DOM-Differentials to Generate High Fidelity Replay of Webpage User Interactions

A computer system for generating replay of a webpage, the computer system comprising:

• a bus system;
• a storage device connected to the bus system, wherein the storage device stores program instructions;
• and
• a processor connected to the bus system, wherein the processor executes the program instructions to:
• retrieve a base document object model (DOM) of the webpage, base DOM differentials of the webpage, and user interactions with the webpage in response to determining that a DOM replay of the webpage is a differential DOM replay;
• patch the base DOM of the webpage with the base DOM differentials of the webpage to generate a patched DOM corresponding to the webpage;
• and
• overlay the user interactions with the webpage on the patched DOM to generate the replay of the webpage.

A computer program product for generating replay of a webpage, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to perform a method comprising:

• responsive to the computer determining that a document object model (DOM) replay of the webpage is a differential DOM replay, retrieving, by the computer, a base DOM of the webpage, base DOM differentials of the webpage, and user interactions with the webpage;
• patching, by the computer, the base DOM of the webpage with the base DOM differentials of the webpage to generate a patched DOM corresponding to the webpage;
• and
• overlaying, by the computer, the user interactions with the webpage on the patched DOM to generate the replay of the webpage.
