xslt_process() with no params?

[Anon]

Hello,

I try to pass a params-array to the xslt_process() function, but nothing happens: It seems the params never reach my xsl-stylesheet. The code looks like this:

/ BEGIN /
$args = array();
$parms = array(
'm-id' => $id
);
$xh = xslt_create();

$result = xslt_process($xh, 'bla.xml', 'bla.xsl', NULL, $args, $parms );

if ($result) {
print $result;
}
xslt_free($xh);

/ END /

The "$id" comes from the URL and should be visible/testable within my xsl-stylesheet. ("xsl:with-param"......)

Any idea whats wrong with that??

Thanks for help,
regards,
Micha.
