Revision history for Perl extension XML::Excel. 0.02 Thursday May 11 9:30:00 2001 -Fixed a problem "Can't call method Value on undefined value". Added line: defined($cell) ? push(@cols_data, $cell->Value) : push(@cols_data, undef); to push an undef value if no data is available for that cell. Thanks to Jean-Marc VANEL. Tuesday May 15 12:30:00 2001 -Added declare_xml() and declare_doctype() functions to allow for xml declaration and doctype declarations. -column headings are now default to instead of <$tag> to conform to XML standard of tag names strting with alphabetic chars or '_'.
