Tomaž Vajngerl b36f7769dd sc: add ODF import/export of the Theme + tests One missing thing is the support in calc to save the Theme into the ODS document and read that back. The theme element is added as a child element to the office:styles - the same as it already is added in Writer. Also adds "Theme" property as a top level document property so it is possible to get and set the theme in xmloff. Also tests have been added to cover this usecases.

ODF Import and Export Filter Logic

The main library "xo" contains the basic ODF import/export filter implementation for most applications. The document is accessed via its UNO API, which has the advantage that the same import/export code can be used for text in all applications (from/to Writer/EditEngine). The filter consumes/produces via SAX UNO API interface (implemented in "sax"). Various bits of the ODF filters are also implemented in applications, for example [git:sw/source/filter/xml].

There is a central list of all element or attribute names in [git:include/xmloff/xmltoken.hxx]. The main class of the import filter is SvXMLImport, and of the export filter SvXMLExport.

The Import filter maintains a stack of contexts for each element being read. There are many classes specific to particular elements, derived from SvXMLImportContext.

Note that for export several different versions of ODF are supported, with the default being the latest ODF version with "extensions", which means it may contain elements and attributes that are only in drafts of the specification or are not yet submitted for specification. Documents produced in the other (non-extended) ODF modes are supposed to be strictly conforming to the respective specification, i.e., only markup defined by the ODF specification is allowed.

There is another library "xof" built from the source/transform directory, which is the filter for the OpenOffice.org XML format. This legacy format is a predecessor of ODF and was the default in OpenOffice.org 1.x versions, which did not support ODF. This filter works as a SAX transformation from/to ODF, i.e., when importing a document the transform library reads the SAX events from the file and generates SAX events that are then consumed by the ODF import filter.

OpenOffice.org XML File Format

There is some stuff in the "dtd" directory which is most likely related to the OpenOffice.org XML format but is possibly outdated and obsolete.

Add New XML Tokens

When adding a new XML token, you need to add its entry in the following three files:

[git:include/xmloff/xmltoken.hxx]
[git:xmloff/source/core/xmltoken.cxx]
[git:xmloff/source/token/tokens.txt]
