simplexml_load_string - Interprets a string of XML into an object

SYNOPSIS

       SimpleXMLElement  simplexml_load_string	(string   $data,  [string  $class_name = "SimpleXMLElement"], [int  $options], [string	$ns = ""],
       [bool  $is_prefix = false])

DESCRIPTION

	Takes a well-formed XML string and returns it as an object.

PARAMETERS

	      o $data
		- A well-formed XML string

	      o $class_name
		- You may use this optional parameter so that simplexml_load_string(3) will return an object of the specified  class.  That  class
		should extend the SimpleXMLElement class.

	      o $options
		- Since PHP 5.1.0 and Libxml 2.6.0, you may also use the $options parameter to specify additional Libxml parameters.

	      o $ns
		- Namespace prefix or URI.

	      o $is_prefix
		- TRUE if $ns is a prefix, FALSE if it's a URI; defaults to FALSE.

RETURN VALUES

	Returns an object of class SimpleXMLElement with properties containing the data held within the xml document, or FALSE on failure.

       Warning

	      This function may return Boolean FALSE, but may also return a non-Boolean value which evaluates to FALSE. Please read the section on
	      Booleans for more information. Use the === operator for testing the return value of this function.

ERRORS
/EXCEPTIONS
	Produces an E_WARNING error message for each error found in the XML data.

       Tip

	       Use libxml_use_internal_errors(3) to suppress all XML errors, and libxml_get_errors(3) to iterate over them afterwards.

EXAMPLES

       Example #1

	      Interpret an XML string

	      <?php
	      $string = <<<XML
	      <?xml version='1.0'?>
	      <document>
	       <title>Forty What?</title>
	       <from>Joe</from>
	       <to>Jane</to>
	       <body>
		I know that's the answer -- but what's the question?
	       </body>
	      </document>
	      XML;

	      $xml = simplexml_load_string($string);

	      print_r($xml);
	      ?>

	      The above example will output:

	      SimpleXMLElement Object
	      (
		[title] => Forty What?
		[from] => Joe
		[to] => Jane
		[body] =>
		 I know that's the answer -- but what's the question?
	      )

	       At this point, you can go about using $xml->body and such.

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:
";
	      echo $doc->saveXML() . "
";

	      echo "Saving only the title part:
";
	      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>
