xslt_set_object - Sets the object in which to resolve callback functions

SYNOPSIS

       bool xslt_set_object (resource  $processor, object  &$obj)

DESCRIPTION

	This function allows to use the $processor inside an $object and to resolve all callback functions in it.

	The  callback  functions  can  be declared with xslt_set_sax_handlers(3), xslt_set_scheme_handlers(3) or xslt_set_error_handler(3) and are
       assumed to be methods of $object.

PARAMETERS

	      o $
		processor -The XSLT processor link identifier, created with xslt_create(3).

	      o $obj
		- An object.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

       Example #1

	      Using your own error handler as a method

	      <?php

	      class my_xslt_processor {

		  var $_xh; // our XSLT processor

		  function my_xslt_processor()
		  {
		      $this->_xh = xslt_create();

		      // Make $this object the callback resolver
		      xslt_set_object($this->_xh, $this);

		      // Let's handle the errors
		      xslt_set_error_handler($this->_xh, "my_xslt_error_handler");
		  }

		  function my_xslt_error_handler($handler, $errno, $level, $info)
		  {
		      // for now, let's just see the arguments
		      var_dump(func_get_args());
		  }
	      }

	      ?>

xslt_set_error_handler - Set an error handler for aXSLTprocessor

SYNOPSIS

       void xslt_set_error_handler (resource  $xh, mixed  $handler)

DESCRIPTION

	Set  an  error	handler  function  for	the XSLT processor given by $xh, this function will be called whenever an error occurs in the XSLT
       transformation (this function is also called for notices).

PARAMETERS

	      o $
		xh -The XSLT processor link identifier, created with xslt_create(3).

	      o $handler
		- The user function needs to accept four parameters: the XSLT processor, the error level, the error code and an array of messages.
		The function can be shown as:
		 error_handler (resource  $xh, int  $error_level, int  $error_code, array  $messages)

RETURN VALUES

	No value is returned.

EXAMPLES

       Example #1

	      xslt_set_error_handler(3) Example

	      <?php

	      // Our XSLT error handler
	      function xslt_error_handler($handler, $errno, $level, $info)
	      {
		// for now, let's just see the arguments
		var_dump(func_get_args());
	      }

	      // XML content :
	      $xml='<?xml version="1.0"?>
	      <para>
	       oops, I misspelled the closing tag
	      </pata>';

	      // XSL content :
	      $xsl='<?xml version="1.0"?>
	      <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
	      <xsl:template match="/">
		 <strong><xsl:value-of select="para"/></strong>
	      </xsl:template>
	      </xsl:stylesheet>';

	      $xh = xslt_create();

	      xslt_set_error_handler($xh, "xslt_error_handler");

	      echo xslt_process($xh, 'arg:/_xml', 'arg:/_xsl',
				NULL, array("/_xml" => $xml, "/_xsl" => $xsl));

	      ?>

	      The above example will output something similar to:

	      array(4) {
		[0]=>
		resource(1) of type (XSLT Processor)
		[1]=>
		int(3)
		[2]=>
		int(0)
		[3]=>
		array(6) {
		  ["msgtype"]=>
		  string(5) "error"
		  ["code"]=>
		  string(1) "2"
		  ["module"]=>
		  string(9) "Sablotron"
		  ["URI"]=>
		  string(9) "arg:/_xml"
		  ["line"]=>
		  string(1) "4"
		  ["msg"]=>
		  string(34) "XML parser error 7: mismatched tag"
		}
	      }
