# Import Filter for File Format of Lotus Word Pro (lwp)
## Description
The import is not direct, but via an intermediate format: StarOffice
XML, the predecessor of ODF (yes, the code is old). 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.
