note that

string DomDocument->

   create_processing_instruction ( string contenido)

takes two arguments:

- first: the processing instruction,

- second: the arguments and values of

      the processing instruction

:::so must be:

string DomDocument->

    create_processing_instruction ( string prInst,

           string contenido)

There's an error in both the above examples: it's "xml-stylesheet," not "xsl-stylesheet.Corrected examples:



    $pi = $dom->create_processing_instruction

    (

      "xml-stylesheet",

      "type=\"text/xsl\" href=\"$stylesheet\""

    );

    $dom->append_child($pi);

That prior user example creates an invalid processing insruction under 4.3.4.  The first parameter is the processing instruction, and the second can be used for the attributes of the PI.   Here's a code snippet I used to insert a stylesheet:



<?php



$pi = $doc->create_processing_instruction(

  "xsl-stylesheet", 

  "type=\"text/xsl\" href=\"$stylesheet\"");

$doc->append_child($pi);



?>

Please note that you have to use this function the following way to add a stylsheetr for client side processing.



$pi = $myDoc->create_processing_instruction('','xsl-stylesheet type="text/xsl" href="path_to_my_stylesheet"');



$myDoc->append_child($pi);



And note you have to add this to the document before the rootnode.
