Using the ODFTOOLKIT

• go to the OdfToolkit site and download the ODFDOM Java API
• follow the instructions in the wiki and install apps that are required
• download Netbeans, open the ODFDOM project and start coding :-)

Loading an ODF file and processing meta.xml

• this is just a really dirty version I hacked
• no XML parsing required so far, just using a regular expression
• it loads an ODT file and displays entries in meta:document-statistic that I considered interesting
• go on and improve!
