The development of the FORTRAN language, so beloved of scientists, pre-dates the development of XML. And it shows. FORTRAN is not a language that manipulates strings with ease, and this makes parsing XML decidedly awkward. So unless you really must use FORTRAN, you are probably better off with C/C++ (or something else more ‘modern’), see for example Daniel Veillard’s LIBXML2 library at http://xmlsoft.org/ or Frank van den Berghen’s parser at http://www.applied-mathematics.net/tools/xmlParser.html.
If you have to use a dialect earlier than FORTRAN-90 (F90), then the chances are you will have to code your own parser.
For later dialects, there are some SDKs available on the Web:
F90
- XMLPARSE - by Arjen Markus at http://xml-fortran.sourceforge.net/
- FoX - by Toby White others at http://uszla.me.uk/space/software/FoX/
F95
- XML - by Mart Rentmeester at http://nn-online.org/code/xml/
Steve King <stephen.king@stfc.ac.uk> (ISIS) has provided a F77 routine that will read cansas1d v1.0 and v1.1 XML files.
