Hi Monks

I'm trying to load from an XML or HTML file into Wx::RichTextCtrl.

I have 2 pieces of code:

(see richtext_test.pl below) is the Perl file with Wx::RichTextHTMLHandler->LoadFile
(see output.xml below) is the XML file I am trying to load (created by ->SaveFile)

The relevant piece of code is:

    my $XML_handler = Wx::RichTextXMLHandler->new;
    $XML_handler->LoadFile ( my $XML_buffer, "output.xml");
    $self->{rich_text_ctrl_1}->SetValue ( $XML_buffer );
[download]

Which creates a handler (no error), tries to load the file and crashes the Perl interpreter with no error message.

Whether I use this code, or the HTML equivalent, which does nothing, except not crash, and no error message. Either way $XML_buffer/$HTML_buffer remains resolutely empty.

What am I doing wrong?

All suggestions gratefully received.

Regards

Steve
