SimpleXMLElement

Example 1 generate XML data

<?Php
header('Content-Type: text/xml');
$e = new SimpleXMLElement('<detils/>');


    $add = $e->addChild('address');
    $add->addChild('door_no', "Door_No: Abcd");
    $add->addChild('Street', "Street NO: 123 Abcd");

print($e->asXML());
?>

<detils>
<address>
<door_no>Door_No: Abcd</door_no>
<Street>Street NO: 123 Abcd</Street>
</address>
</detils>

Example 2 generate XML by looping

<?Php
header('Content-Type: text/xml');
$e = new SimpleXMLElement('<detils/>');

for ($i = 1; $i <= 4; ++$i) {
    $add = $e->addChild('address');
    $add->addChild('door_no', "Door_No $i");
    $add->addChild('Street', "Street NO $i");
}
print($e->asXML());
?>

<detils>
<address>
<door_no>Door_No 1</door_no>
<Street>Street NO 1</Street>
</address>
<address>
<door_no>Door_No 2</door_no>
<Street>Street NO 2</Street>
</address>
<address>
<door_no>Door_No 3</door_no>
<Street>Street NO 3</Street>
</address>
<address>
<door_no>Door_No 4</door_no>
<Street>Street NO 4</Street>
</address>
</detils>

Example 2: Parsing XML and Accessing Child Elements

Using SimpleXMLElement, we can access child elements of an XML document directly:

$xml_data = '<books><book><title>PHP Basics</title></book></books>';
$xml = new SimpleXMLElement($xml_data);
echo $xml->book->title; // Outputs: PHP Basics

Example 4: Looping Through Multiple Child Elements

Here’s how to loop through multiple elements in an XML structure:

$xml_data = '<books><book><title>PHP Basics</title></book><book><title>MySQL Guide</title></book></books>';
$xml = new SimpleXMLElement($xml_data);
foreach ($xml->book as $book) {
    echo $book->title . "<br>";
}
// Outputs:
// PHP Basics
// MySQL Guide

Example 5: Modifying XML Elements

You can modify the content of an XML element using SimpleXMLElement:

$xml->book[0]->title = "Advanced PHP";
echo $xml->asXML(); 
// Outputs the updated XML structure
