|I finally figured out how to make the special characters display
properly and be searchable. In gsdl/perllib/doc.pm, in the subroutine
buffer_section_xml, after the line:
my $escaped_value = &_escape_text($data->);
add the line:
my $junk = substr $escaped_value,0;
then change the next line,
$all_text .= ' <Metadata name="' . $data-> . '">' .
$escaped_value . "</Metadata>
$all_text .= ' <Metadata name="' . $data-> . '">' . $junk .
For some reason, which I haven't yet determined, whenever the presence
of the metadata.xml file causes _non-default_ metadata to be written to
the doc.xml file, $data-> becomes typed as something other than a
string. The line my $junk ... forces it back into string format, and
everything is fine. Since $data-> should just contain string data
(when I print it, that's all I see), I'm wondering if this isn't some
sort of perl bug--I'm using perl 5.6.1 for Linux.
I still have the problem with one of my files (of the three I've tried)
where the first instance of the entity ü is passed through to
doc.xml as &uuml;. The resulting HTML file, generated on the fly,
has ü, which displays properly but can't be searched. However, I
can live with the occasional anomaly at this stage of the game, so I
probably won't try to track this problem down.
Thanks for the help.
