How can I view the OpenDocument format?
The OpenDocument file format used by StarOffice Software is a native XML format without any binary data. Sub-elements, such as pictures, are placed in the original file format in the XML file. The XML format specification is located at http://www.oasis-open.org/committees/tc_home.php?wg_abbrev=office. OpenDocument files are saved as archive files (ZIP format), because they actually contain several sub-elements like pictures, macros and styles. To explore the real XML content, you need to unpack the document file (e.g. ending with .odt). You will then find the XML content in a file named content.xml.
