DOMDocument->saveXML()

(no version information, might be only in CVS)

Creates an XML document from the DOM representation. This function is usually
called after building a new dom document from scratch as in the example below.

Use this parameter to output only a specific node without XML declaration
rather than the entire document.

Additional Options. Currently only LIBXML_NOEMPTYTAG is supported.

Returns the XML, or FALSE if an error occurred.

Raised if node is from another document.

Example 1. Saving a DOM tree into a string

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