PHP SimpleXML

previous next

SimpleXML handles the most common XML tasks and leaves the rest for other extensions.


What is SimpleXML?

SimpleXML is new in PHP 5. It is an easy way of getting an element's attributes and text, if you know the XML document's layout.

Compared to DOM or the Expat parser, SimpleXML just takes a few lines of code to read text data from an element.

SimpleXML converts the XML document into an object, like this:

SimpleXML is fast and easy to use when performing basic tasks like:

However, when dealing with advanced XML, like namespaces, you are better off using the Expat parser or the XML DOM.


Installation

As of PHP 5.0, the SimpleXML functions are part of the PHP core. There is no installation needed to use these functions.


Using SimpleXML

Below is an XML file:

<?xml version="1.0" encoding="ISO-8859-1"?>
<note>
<to>Tove</to>
<from>Jani</from>
<heading>Reminder</heading>
<body>Don't forget me this weekend!</body>
</note>

We want to output the element names and data from the XML file above.

Here's what to do:

  1. Load the XML file
  2. Get the name of the first element
  3. Create a loop that will trigger on each child node, using the children() function
  4. Output the element name and data for each child node

Example

<?php
$xml = simplexml_load_file("test.xml");
echo $xml->getName() . "<br />";
foreach($xml->children() as $child)
  {
  echo $child->getName() . ": " . $child . "<br />";
  }
?>

The output of the code above will be:

note
to: Tove
from: Jani
heading: Reminder
body: Don't forget me this weekend!
