Hmm I thought the closing xml was well formed, I was wrong. Thanks
Now I dont get parsing errors now but the transformation is not
returning anything new, just the comment segment as it was before
sending it to rdfpic2html. I am trying to modify
http://www.ozhiker.com/electronics/pjmt/ PJMT's JPEG.php to transform
http://jigsaw.w3.org/rdfpic/ rdfpic xml in the comment segment of jpegs
and return it to Example.php
function Interpret_Comment_to_HTML( $jpeg_header_data )
{
// Create a string to receive the output
$output = "";
// read the comment segment
$comment = get_jpeg_Comment( $jpeg_header_data );
// Check if the comment segment was valid
if ( $comment !== FALSE )
{
// Check if the string contains an indicator that there may be
rdfpic metadata
if (stristr($comment, 'PhotoRDF') !== FALSE)
{
$rdfpicdata = stristr($comment, '<?xml');
rdfpic2html( $rdfpicdata );
$output .= $rdfpichtml;
}
// Comment exists - add it to the output
$output .= "<h2
class=\"JPEG_Comment_Main_Heading\">JPEG Comment</h2>\n";
$output .= "<p
class=\"JPEG_Comment_Text\">$comment</p>\n";
}
// Return the result
return $output;
}
function rdfpic2html( $rdfpicdata )
{
$arguments = array('/_rdf' => $rdfpicdata);
$xsltproc = xslt_create();
xslt_set_encoding($xsltproc, 'ISO-8859-1');
$rdfpichtml = xslt_process($xsltproc, 'arg:/_rdf', 'rdfpic.xsl',
NULL, $arguments);
if (empty($rdfpichtml)) {
die('XSLT processing error: '. xslt_error($xsltproc));
}
xslt_free($xsltproc);
return $rdfpichtml;
}
rdfpic.xsl:
