SimpleXML is a PHP extension that allows us to easily manipulate and get XML data.

PHP SimpleXML – Get Node Values
Get the node values from the “note.xml” file:

Example
<?php
$xml=simplexml_load_file(“note.xml”) or die(“Error: Cannot create object”);
echo $xml->to . “
“;
echo $xml->from . “
“;
echo $xml->heading . “
“;
echo $xml->body;
?>
The output of the code above will be:

Tove
Jani
Reminder
Don’t forget me this weekend!
Another XML File
Assume we have an XML file called “books.xml”, that looks like this:

 
    Everyday Italian
    Giada De Laurentiis
    2005
    30.00
 
 
    Harry Potter
    J K. Rowling

    29.99
 
 
    XQuery Kick Start

PHP SimpleXML – Get Node Values of Specific Elements
The following example gets the node value of the element in the first and second elements in the “books.xml” file:

Example
<?php
$xml=simplexml_load_file(“books.xml”) or die(“Error: Cannot create object”);
echo $xml->book[0]->title . “
“;
echo $xml->book[1]->title;
?>
The output of the code above will be:

Everyday Italian
Harry Potter
PHP SimpleXML – Get Node Values – Loop
The following example loops through all the elements in the “books.xml” file, and gets the node values of the , , , and elements:

Example
<?php
$xml=simplexml_load_file(“books.xml”) or die(“Error: Cannot create object”);
foreach($xml->children() as $books) {
    echo $books->title . “, “;
    echo $books->author . “, “;
    echo $books->year . “, “;
    echo $books->price . “
“;
}
?>
The output of the code above will be:

Everyday Italian, Giada De Laurentiis, 2005, 30.00
Harry Potter, J K. Rowling, 2005, 29.99
XQuery Kick Start, James McGovern, 2003, 49.99
Learning XML, Erik T. Ray, 2003, 39.95
PHP SimpleXML – Get Attribute Values
The following example gets the attribute value of the “category” attribute of the first element and the attribute value of the “lang” attribute of the element in the second element:

Example
<?php
$xml=simplexml_load_file(“books.xml”) or die(“Error: Cannot create object”);
echo $xml->book[0][‘category’] . “
“;
echo $xml->book[1]->title[‘lang’];
?>
The output of the code above will be:

COOKING
