The entry point to +the filter is class LotusWordProImportFilter (refer to Source code +section), but that just hooks up the necessary machinery for processing +StarOffice XML produced by the filter. The real fun starts in function +`ReadWordproFile()` (`source/filter/lwpfilter.cxx`); this function +initializes the parser (class `Lwp9Reader`) and the SAX XML handler that +produces the output (class `XFSaxStream`). The Lwp9Reader class then does +the actual parsing. + +If the module is built with debug level greater than 0, it is possible +to examine the intermediate XML: set environment variable +`DBG_LWPIMPORT_DIR=` to an existing directory and, on opening an lwp +document, a file named `lwpimport.xml` will be created in that directory. + +## Source Code + +### Module Contents +* `inc`: module-global headers (can be included by any file in source) +* `qa`: `cppunit` tests +* `source`: the filter itself +* `util`: UNO passive registration config + +### Source Contents +* `filter`: `lwp` document format parser +* `filter/LotusWordProImportFilter.cxx`: the entry point to the filter +* `filter/xfilter`: export to StarOffice XML |
