Re: [xsl] Does the new structure include the same text content?

Hi Gerrit,
Good to know that I may be on the right track with the normalized text diff.
It would be almost impossible to go back to the original SGML structure from
the XML. The main difficulty is that a lot of the structure in the SGML uses
inclusions to allow tables and figures in almost any location. That SGML
feature was always a recipe for untidy documents!

Hi Ian,

diffing normalized text output is a good approach in my experience.
However, if the 4.1 structures differ significantly from 1.7 as you say, it
might be a good idea to transform the 4.1 output back to 1.7 prior to the
diff. Or maybe not "transform it back to match the input exactly", but only to
such a degree that the text files will be the same if no content was lost or
duplicated.
