TXmlTransform uses the PHP's XSL extension to perform
{@link http://www.w3.org/TR/xslt XSL transformations} using the
{@link http://xmlsoft.org/XSLT/ libxslt library}.
To associate an XML style sheet with TXmlTransform set the
{@link setTransformPath TransformPath} property to the namespace or path to the style sheet
or set the {@link setTransformContent TransformContent} property to the XML style sheet
data as a string.
To associate the XML data to be transformed set the {@link setDocumentPath DocumentPath}
property to the namespace or path to the XML document or set the
{@link setDocumentContent DocumentContent} property to the XML data as a string.
To add additional parameters to the transformation process you can use the {@link getParameters Parameters}
property.
