SimpleXMLElement::asXML

(PHP 5 >= 5.0.1)

SimpleXMLElement::asXML — Return a well-formed XML string based on SimpleXML element

Beschreibung

public mixed SimpleXMLElement::asXML ([ string $filename ] )

The asXML method formats the parent object's data in XML version 1.0.

Parameter-Liste

filename: If specified, the function writes the data to the file rather than returning it.

Rückgabewerte

If the filename isn't specified, this function returns a string on success and FALSE on error. If the parameter is specified, it returns TRUE if the file was written successfully and FALSE otherwise.

Beispiele

Beispiel #1 Get XML


<?php
$string = <<<XML
<a>
 <b>
  <c>text</c>
  <c>stuff</c>
 </b>
 <d>
  <c>code</c>
 </d>
</a>
XML;

$xml = new SimpleXMLElement($string);

echo $xml->asXML();

?>

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

<?xml version="1.0"?>
<a>
 <b>
  <c>text</c>
  <c>stuff</c>
 </b>
 <d>
  <c>code</c>
 </d>
</a>

asXML also works on Xpath results:

Beispiel #2 Using asXML() on SimpleXMLElement::xpath() results


<?php
// Continued from example XML above.

/* Search for <a><b><c> */
$result = $xml->xpath('/a/b/c');

while(list( , $node) = each($result)) {
    echo $node->asXML();
}
?>

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

<c>text</c><c>stuff</c>

Function asXML decodes special chars like ø, æ and others to &#xE6;, &#xF8;



To get normal output use without quoting:



$xml = html_entity_decode($xml, ENT_NOQUOTES, 'UTF-8');

Code snippet to load a XML document, increment an attribute and store it again.


My XML looks like:


<?xml version="1.0" encoding="ISO-8859-1"?>


<doctypes counter="16">


    <doctype id="d1">


        <name>Carta</name>


        <acro>CA</acro>


    </doctype>


...


</doctypes>





I want to retrieve the counter attribute, increment it, and store the new document at the end:





<?php


  $document = simplexml_load_file("mydoc.xml");


  $cont = (integer) $document['counter'];


  $document['counter'] = $cont+1;


  $document->asXML("mydoc.xml");


?>
