How do you parse and process HTML/XML in PHP?

Question

Aryan Kumar · Answer

There are two main ways to parse HTML/XML in PHP:
Use the SimpleXML class. The
SimpleXML class is a PHP class that can be used to parse and manipulate XML data. The
SimpleXML class creates an object tree that represents the XML data. You can then access the elements of the XML data by using the object tree.
For example, the following code parses an XML file and prints the name of the first employee:
PHP
andlt;?php
// Load the XML file
$xml_data = file_get_contents("data.xml");
// Create a SimpleXMLElement object
$xml_obj = new SimpleXMLElement($xml_data);
// Print the name of the first employee
echo $xml_obj->employee[0]->name;
?>
Use the DOM class. The
DOM class is a PHP class that can be used to parse and manipulate HTML and XML data. The
DOM class creates a document object model (DOM) that represents the HTML or XML data. You can then access the elements of the HTML or XML data by using the DOM.
For example, the following code parses an HTML file and prints the text of the first heading:
PHP
andlt;?php
// Load the HTML file
$html_data = file_get_contents("index.html");
// Create a DOMDocument object
$dom_document = new DOMDocument();
$dom_document->loadHTML($html_data);
// Get the first heading
$heading = $dom_document->getElementsByTagName("h1")[0];
// Print the text of the heading
echo $heading->textContent;
?>
Which method you use to parse HTML/XML in PHP depends on your specific needs. If you are familiar with object-oriented programming, then the
SimpleXML class is a good choice. If you are not familiar with object-oriented programming, then the
DOM class is a good choice.
