Document Object Model (DOM) is a platform and language 
neutral interface that allows programs and scripts to 
dynamically access and update the content, structure, and 
style of a document.

SOAP is a protocol for exchanging XML-based messages over a 
computer network, normally using HTTP. SOAP forms the 
foundation layer of the web services stack, providing a 
basic messaging framework that more abstract layers can 
build on. SOAP facilitates the Service-Oriented 
architectural pattern.
