xslt_set_sax_handler - Set SAX handlers for a XSLT processor

SYNOPSIS

       void xslt_set_sax_handler (resource  $xh, array	$handlers)

DESCRIPTION

	Set SAX handlers on the resource handle given by $xh.

PARAMETERS

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

	      o $handlers
		- SAX handlers should be a two dimensional array with the format (all top level elements are optional):

	      array(
	      [document] =>
		  array(
		      start document handler,
		      end document handler
		  ),
	      [element] =>
		  array(
		      start element handler,
		      end element handler
		  ),
	      [namespace] =>
		  array(
		      start namespace handler,
		      end namespace handler
		  ),
	      [comment] => comment handler,
	      [pi] => processing instruction handler,
	      [character] => character data handler
	      )

XSLT_SET_SCHEME_HANDLERS(3)						 1					       XSLT_SET_SCHEME_HANDLERS(3)

xslt_set_scheme_handlers - Set the scheme handlers for theXSLTprocessor

SYNOPSIS

       void xslt_set_scheme_handlers (resource	$xh, array  $handlers)

DESCRIPTION

	Registers the scheme handlers (XPath handlers) for the document.

PARAMETERS

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

	      o $handlers
		- An array with the following keys: "get_all", "open", "get", "put", and "close".  Every entry must be a function name or an array
		in the following format: array($obj, "method").  Note that the given array does not need to contain all of  the  different  scheme
		handler  elements  (although it can), but it only needs to conform to the "handler" => "function" format described above.  Each of
		the individual scheme handler functions called are in the formats below:

	      string   get_all(resource processor, string scheme, string rest)
	      resource open(resource processor, string scheme, string rest)
	      int      get(resource processor, resource fp, string &data)
	      int      put(resource processor, resource fp, string data)
	      void     close(resource processor, resource fp)

RETURN VALUES

	No value is returned.

EXAMPLES

       Example #1

	      xslt_set_scheme_handlers(3) example

	       For example, here is an implementation of the "file_exists()" PHP function.

	      <?php

	      // Definition of the handler
	      function mySchemeHandler($processor, $scheme, $rest)
	      {
		  $rest = substr($rest,1);    // to remove the first / automatically added by the engine
		  if ($scheme == 'file_exists') {
		      // result is embedded in a small xml string
		      return '<?xml version="1.0" encoding="UTF-8"?><root>' . (file_exists($rest) ? 'true' : 'false') . '</root>';
		  }
	      }

	      $SchemeHandlerArray = array('get_all' => 'mySchemeHandler');

	      // Start the engine
	      $params = array();
	      $xh = xslt_create();

	      xslt_set_scheme_handlers($xh, $SchemeHandlerArray);

	      $result = xslt_process($xh, "myFile.xml", "myFile.xsl", NULL, array(), $params);
	      xslt_free($xh);

	      echo $result;

	      ?>

	       Then, inside the stylesheet, you can test whether a certain file exists with:

	      <xsl:if test="document('file_exists:anotherXMLfile.xml')/root='true'">
	       <!-- The file exist -->
	      </xsl:if>
