Beginner : Needs Help

Hi ,

I was trying to find some programs that convert XML documents to
s-expressions. I need s-expresion equivalent input of a collection of XML
documents to my program. I got "S-exp-based XML parsing" /SSAX project's
source-forge home page. I am new to Scheme programming language.
I could not run the programs in SSAX package , and could not make out the
reason for that. Please help.

I am using bigloo compiler on Fedora Core 3, and i was able to run the
scheme examples came with bigloo distribution. Compiler is working ok. I
hav installed bigloo in a personal folder, not in /usr/local.

These are my doubts, Sir ..

1. I want to read a set of XML files and get the s-expression equivalent.
Which all files in the distribution should i use ? in run-sxml.scm, no lib
files are included. Do i need only this file to get SXML equivalent of a
XML document ?

2. Can I call the XML-SXML conversion module from a C/C++ file ? I want to
use the resulting s-expression as an input to a CPP file.. Bigloo provides
interfacing with C, so can I use this module also like that ? Please give
hints if you know how to call scm modules from a c program. Or next
option, I felt is to write my Makefile such that it pipes the sxml output
to C++ file i-stream.

3:I got warning messages and no executables while trying to compiler SSAX.
Please tell where did I make mistake ? What should i do to get the
executables and see them run correct ?


The make command in lib directory gave this lines in terminal

rm -f SSAX-code.scm *.o

In examples directory , the command <make PLATFORM=biglooc all> gave:

Makefile:173: warning: overriding commands for target
`run-remove-markup-bigloo'
Makefile:129: warning: ignoring old commands for target
`run-remove-markup-bigloo'
Makefile:177: warning: overriding commands for target `run-outline-bigloo'
Makefile:129: warning: ignoring old commands for target `run-outline-bigloo'
Makefile:181: warning: overriding commands for target `run-sxml-bigloo'
Makefile:129: warning: ignoring old commands for target `run-sxml-bigloo'
make: *** No rule to make target `../lib/SSAX-code.scm', needed by
`run-remove-markup-bigloo'.  Stop.


In tests folder , the same command gave

echo "(module test (include \"myenv-bigloo.scm\") (include
\"catch-error.scm\") (include \"env.scm\") (include \"srfi-13-local.scm\")
(include \"util.scm\") (include \"vmyenv.scm\"))" > /tmp/a.scm        ;
bigloo -I ../lib -eval "(set! *load-path* (cons \"../lib\" *load-path*))"
-call/cc -farithmetic -unsafea -o  vmyenv /tmp/a.scm     && rm -f
/tmp/a.scm     && ./vmyenv
/tmp/a.scm:

*** WARNING:bigloo:install-compiler-expander

4. It will be really helpful if  I can get a user manual for SSAX.


Thanks a lot for your time. I am stuck up, and tried all possible ways I
can. Please help.
