NAME
XMLwriterSimple - Light weight re-implementation of XML::Writer. This module is used internally by Excel::Writer::XLSX. DESCRIPTION
This module is used by Excel::Writer::XLSX for writing XML documents. It is a light weight re-implementation of XML::Writer. XMLwriterSimple is approximately twice as fast as XML::Writer. This speed is achieved at the expense of error and correctness checking. In addition not all of the XML::Writer methods are implemented. As such, XMLwriterSimple is not recommended for use outside of Excel::Writer::XLSX. If required XMLwriterSimple can be overridden and XML::Writer can be used in its place by setting an "_EXCEL_WRITER_XLSX_USE_XML_WRITER" environmental variable: export _EXCEL_WRITER_XLSX_USE_XML_WRITER=1 perl example.pl Or for one off programs: _EXCEL_WRITER_XLSX_USE_XML_WRITER=1 perl example.pl This technique is used for verifying the test suite with both XMLwriterSimple and XML::Writer: _EXCEL_WRITER_XLSX_USE_XML_WRITER=1 prove -l -r t SEE ALSO
