Loading and Saving XML Documents
There are two ways to import documents into a DOM tree; the first is by loading them
from a file:
$dom = new DomDocument();
$dom->load("library.xml");
Alternatively, you can load a document from a string—which is handy when using
REST Web services:
$dom = new DomDocument();
$dom->loadXML($xml);
You, can also import HTML files and strings by calling the
DomDocument::loadHTMLFile() and DomDocument::loadHTML() methods respectively.
Just as simply, you can save XML documents using one of DomDocument::save()
(to a file), DomDocument::saveXML() (to a string), DomDocument::saveHTML() (also
to a string, but saves an HTML document instead of an XML file), and
DomDocument:saveHTMLFile() (to a file in HTML format).
$dom = new DomDocument();
$dom->load(’library.xml’);
// Do something with our XML here
