Processing custom XML namespace within XSL

Question

I'm using the php class XSLTProcessor to generate HTML from a xsl. Within the xsl, I'd like all my custom namespace elements to be processed by my own processor class.

So for example:

<xsl:for-each select="doc/elements/*">
    <doc:renderElement element="." />
</xsl:for-each>

This should call the method renderElement of an instance of my custom processor class.

I know I can enable calling php functions by using the registerPHPFunctions function. However, this only seems to support calling static methods.

Answer 1

Yes, XSLTProcessor::registerPHPFunctions only supports static function calls of classes. However you can make use of those static calls to provide a factory or instance registry to provide actual objects. In your case probably based on the element name.

Existing code where this is done can be found in the PIWI - PHP Transformation Framework.
