PHP XML DOM Parser
The built-in DOM parser makes it possible to process XML documents in PHP.
The XML DOM Parser
The DOM parser is a tree-based parser.Look at the following XML document fraction:
<?xml version="1.0" encoding="UTF-8"?>
<from>Jani</from> The DOM sees the XML above as a tree structure: - Level 1: XML Document
- Level 2: Root element: <from>
- Level 3: Text element: "Jani"
Installation
The DOM parser functions are part of the PHP core. There is no installation needed to use these functions.The XML File
The XML file below ("note.xml") will be used in our example:<?xml version="1.0" encoding="UTF-8"?>
