PHP XML Classes

PHP XML Classes
A collection of classes and resources to process XML using PHP

Description: This is an abstraction class for the XSLT extension. This version works with the new XSLT extension from PHP 1.1, the class allows to transform XML documents using XSLT stylesheets passing the xml/xslt as a file or as a PHP string.

Xslt (class_xslt.php)

PHP XML Classes

Xslt (class_xslt.php)

Description: This class is an abstraction class for an XSLT processor, it let's you setup the XML to be processed and the XSLT stylesheet to use from a file or a PHP string. This implementation uses the Sablotron XSLT processor and was updated to work with the new PHP 4.1.x xslt extension.

NEWS:

07-04-2002 Documentation updated and package rebuilt.
05-15-2002 Updated to work under PHP 4.2.x

Requirements

PHP 4.0.5+
XSLT extension

Features

To-dos

Can receive the XML source as a string or a file (http://) works too.
Can receive the XSLT stylesheet as a string or a file (http://) works too.

Option to cache transformations for incresed speed.

Detailed description and usage:
Using the class:

include_once("class_xslt.php");
$xslt=new Xslt();
$xslt->setXml("applications.xml"); // or setXmlString($xml) if the xml is in a php string
$xslt->setXsl("tr1.xsl");          // or steXslString($xsl) if the xsl is in a php string
if($xslt->transform()) {
   $ret=$xslt->getOutput();
   echo $ret;
} else {
   print("Error:".$xslt->getError());
}
