IBM Lotus Forms (Formerly Workplace Forms, PureEdge)

Altough not Free Software, Lotus Forms produces well-formed XML.

Decoding XDFL files saved with 'encoding=base64'.

• Files saved with:

  application/vnd.xfdl;content-encoding="base64-gzip"
  are simple base64-encoded gzip files. They can be easily restored to XML by first decoding and then unzipping them. This can be done as follows on Ubuntu:
  sudo apt-get install uudeview uudeview -i yourform.xfdl gunzip -S "" < UNKNOWN.001 > yourform-unpacked.xfdl

  The first command will install uudeview, a package that can decode base64, among others. You can skip this step once it is installed.

  Assuming your form is saved as 'yourform.xfdl', the uudeview command will decode the contents as 'UNKNOWN.001', since the xfdl file doesn't contain a file name. The '-i' option makes uudeview uninteractive, remove that option for more control.

  The last command gunzips the decoded file into a file named 'yourform-unpacked.xfdl'.
