PHP - XML Introduction

Hello folks! welcome to another section of our tutorial on PHP. In this section of our PHP tutorial, we will be discussing about few XML concepts.

XML is a mark-up language that is used to share data across the web, xml is meant for human readability and machine readability. Example of share-able xmls are RSS Feeds. Xml parsers are useful in reading and updating the data using web browsers.

Types of XML

There are two types of XML -

  • Tree based XML
  • Event based XML

XML Parser Extensions

The xml parser extensions works based on libxml. The following xml parsers are available in core PHP.

  • Simple XML Parser
  • Dom XML Parser
  • XML Parser
  • XML Reader

Simple XML Parser

Simple xml parser also called a tree based xml parser is used to parse the simple xml file. It calls the simplexml_load_file() method to get access to the xml file from a specific path.

Dom Parser

Dom parser also called a complex node parser, is used for parsing highly complex xml files. It is used as interface to modify the xml file. The Dom parser is encoded with the UTF-8 character encoding.

XML Parser

The xml parser is based on a SAX parse. It is more faster than all the above parsers. It will create and parse the xml files. Xml parser is encoded by ISO-8859-1, US-ASCII and UTF-8 character encoding.

XML Reader
Xml reader parser also know as Pull xml parser, is used to read the xml file in a more faster manner. It functions with a high complex xml document with xml validation.
