You don't understand the basic concept.
DOM (Document Object Model) is a tree representing the structure
of a document, where the elements (logically separated parts of)
content is enclosed within tags to allow for computerized
processing. IE exposes it's own version of DOM through its
implementations of JS. If you want to access and manipulate a HTML
document in PHP using this tree-like abstraction (DOM), you will
have to use XML DOM library. No XML parser is an integral part of
the language.
