I recently wrote a perl function to be called from LibXSLT (1.53) like this:
# in httpd.conf
<Perl>
my $xsltfunc = sub { .... return $ok ? 1 : 0 }
XML::LibXSLT->register_function( "urn:my", "xsltfunc", $xsltfunc );
</Perl>
And the corresponding XSL template looked like:
<xsl:choose>
<xsl:when test="my:xsltfunc(node) = 1">
...
</xsl:when>
...
</xsl:choose>
Sure enough, it worked. So I went on to create another function, which
was going to be called from the same <xsl:template> as above function.
I pretty much cut n' pasted the code, used the same namespace, different
function name (duh), and added another <xsl:choose> in the template to
use the function. And now all of the sudden everything stopped working,
and the only error I get is "Can't coerce ARRAY in entersub..." error .
Upon encountering this, I tried buncha different combinations, and it
looked to me that these functions may fail kind of randomly depending on
where you call them? It's even weird, because I see that my second
function is actually being called, but the there's some problem with
using its results or some such thing.
I know this is vague, but has anybody else seen anything like this
before, or was I smoking something...?
