A processing-instruction does not execute the code within. The following
example:

<xsl:template match="/">
<xsl:processing-instruction name="foo">
<xsl:text>type="txt/xml"</xsl:text>
</xsl:processing-instruction>
</xsl:template>

Only generates the following tag in the output:

<?foo type="txt/xml"?>

Which doesn't do anything.

If you want to use PHP functions in your XSLT stylesheet, you can do this
through the document() function.

See the examples in the following manual page:

http://nl2.php.net/manual/en/functio...e-handlers.php

And yes, this requires the parsing of the stylesheet to be done by PHP's
XSLT extension...
