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 "Retrieving all the document:\n"; echo $doc->saveXML() . "\n"; echo "Retrieving only the title part:\n"; echo $doc->saveXML($title); ?>
The above example will output:
Retrieving all the document: <?xml version="1.0"?> <book> <title>This is the title</title> </book> Retrieving only the title part: <title>This is the title</title>
