Welcome to the KWord 1.3 to OOWriter/OASIS import filter
|
|
|
|
|
|
Note: the information in this file is meant for developers, not for end users.
|
|
|
|
|
|
Following are a few points about some particularities when developing this filter.
|
|
|
|
=== Multi-Pass Overview ===
|
|
The filter is a 4 pass filter.
|
|
|
|
1. Parsing
|
|
1a parsing documentinfo,xml (done classicaly with QDom)
|
|
1b parsing maindoc.xml (class KWord13Parser, done with TQt's SAX parser: TQXml)
|
|
2. Postprocessing of parsing (class KWord13PostParsing)
|
|
* loading of pictures
|
|
* grouping tables cells (currently not done)
|
|
* placing bookmarks (currently not done)
|
|
3. Preparing the OASIS document (function KWord13OasisGenerator::prepare)
|
|
* creating automatical styles
|
|
4. Generating the OASIS document (function KWord13OasisGenerator::generate)
|
|
4a creating the files content.xml, styles.xml, meta.xml
|
|
4b writing pictures
|
|
4c writing manifest file
|
|
|
|
=== Syntax Versions ===
|
|
|
|
KWord has a few syntax variants, starting with the 3 official syntax versions
|
|
(called 1, 2 and 3) but there is also KWord files predating syntax 1 and also
|
|
the files generated by KWord import filters might differ too.
|
|
|
|
There are 2 big syntax groups: the old syntax and the new one. The old syntax
|
|
is syntax 1 or older, the new syntax starts with syntax 2.
|
|
|
|
The aim of this filter is to support any file claimed to be a KWord file (as the
|
|
user has not chosen the version with which he has generated the file.)
|
|
|
|
So be careful when modifying code not to remove support for other syntaxes (be
|
|
it newer or older ones). This also means not to assume that a certain tag or
|
|
attribute always exists in a KWord tag. Only very few ones do so.
