A use exemple of this method :



Usefull for generating an XML linked with a XSLT !



<?php



// "Create" the document.

$xml = new DOMDocument( "1.0", "ISO-8859-15" );



//to have indented output, not just a line

$xml->preserveWhiteSpace = false;

$xml->formatOutput = true;



// ------------- Interresting part here ------------



//creating an xslt adding processing line

$xslt = $xml->createProcessingInstruction('xml-stylesheet', 'type="text/xsl" href="base.xsl"');



//adding it to the xml

$xml->appendChild($xslt);



// ----------- / Interresting part here -------------



//adding some elements

$root = $xml->createElement("list");

$node = $xml->createElement("contact", "John Doe");

$root-> appendChild($node);

$xml-> appendChild($root);



//creating the file

$xml-> save("output.xml");



?>



output.xml :



<?xml version="1.0" encoding="ISO-8859-15"?>

<?xml-stylesheet type="text/xsl" href="base.xsl"?> //the line has been created successfully

<list>

  <contact>John Doe</contact>

</list>
