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:

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

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:

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 . "
