SimpleXML - Get Node/Attribute Values
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
$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:

30.00
Harry Potter
J K. Rowling
2005
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
$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
$xml=simplexml_load_file("books.xml") or die("Error: Cannot create object");
foreach($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

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 theelement in the second element:

echo $xml->book[0]['category'] . "

echo $xml->book[1]->title['lang'];
?>
The output of the code above will be:
COOKING
