Creating XML Filters

Creating an XML Filter for LibreOffice

When you create an XML filter for LibreOffice, you need to design an XSLT stylesheet that can convert to and from the OpenDocument XML file format.

For more information about the OpenDocument XML format, go to https://www.openoffice.org/xml/.


If you want, you can include a template with your filter to apply LibreOffice styles to an XML document that you import.

To Create an XML Filter

  1. Create an XSLT transformation stylesheet that maps the elements of the external XML format to the elements of the OpenDocument XML file format and back again.

  2. Create a template that assigns LibreOffice styles to elements in the external XML format when you import a file in this format into LibreOffice.

  3. In LibreOffice Writer, create a text document, and choose Tools - XML Filter Settings.
