xslt php create xml from string

Question

I've used the following piece of code to transform XML to another XML file. But I'm trying to use XSLT to create a new XML file from a set of strings.

$xsl  = simplexml_load_file('template.xsl');
$xslt = new XSLTProcessor;
$xslt->setParameter('', 'foo', $foo);
$xslt->setParameter('', 'bar', $bar);
$xslt->setParameter('', 'test', $test);

$xslt->importStyleSheet($xsl);

$data = $xslt->transformToXML($xml);

So what I'm doing is passing parameters to template.xsl which creates nodes and the resulting output is passed to $data, which PHP then writes to a file.

But the example code that I have expects a XML file to be read first and saved to a variable, $xml. But I'm not reading in a XML file because I'm generating strings for the data and this generates a warning:

PHP Warning: XSLTProcessor::transformToXml() expects parameter 1 to be object, null given

I realise that I can use PHP to write the XML - http://www.developerfusion.com/code/3944/how-to-create-xml-files/ - But I would like to know how to do this with XSLT.

You can use any XML document to pass as the first parameter of XSLTProcessor::transformToXml()

It can be an artificial document such as <t/> -- loaded from file.

In order not to load any additional XML file, one can use the already loaded XSLT file:

 $data = $xslt->transformToXML($xsl);

In the transformation you will have a single template (matching /) and inside this template you'll generate the wanted XML document - result.
