DOM and SAX are two APIs for working with XML documents. DOM loads the entire XML document into memory as a tree structure, allowing manipulation of the document. SAX is event-based and reads the XML document sequentially, invoking callback functions at element boundaries. Compared to DOM, SAX uses less memory but only allows reading of the document. Both APIs are supported across many programming languages including PHP.
