However, implementations of the W3C DOM Core API do not require a way so
that a document tree can be built from source code, nor is XPath support
required. So you had better RTFM yourself before making the suggestion.
There are few if any occasions where such wild guesses are useful. Lucky
for you, you hit the nail this time: there are corresponding methods in
this (PHP’s) implementation (so there is no need to search the Web).
