Examples

Example #1 Saving a DOM tree into a string


<?php



$doc = new DOMDocument('1.0');

// we want a nice output

$doc->formatOutput = true;



$root = $doc->createElement('book');

$root = $doc->appendChild($root);



$title = $doc->createElement('title');

$title = $root->appendChild($title);



$text = $doc->createTextNode('This is the title');

$text = $title->appendChild($text);



echo "Saving all the document:\n";

echo $doc->saveXML() . "\n";



echo "Saving only the title part:\n";

echo $doc->saveXML($title);



?>

The above example will output:

Saving all the document:
<?xml version="1.0"?>
<book>
  <title>This is the title</title>
</book>

Saving only the title part:
<title>This is the title</title>
