PureEdge viewer is an e-form editor used by large businesses, the US Government (IRS, DOD, etc) and probably more. PureEdge forms are ASC-GZIP compressed XML documents with a file extension of XFD or XFDL. File headers usually (always?) begin with: 'application/x-xfdl;content-encoding="asc-gzip"' Someone has written a perl script to decompress the form and output the XML.
