Hello Tom,



Here is some feedback on your XMLToolbox 0.3. I was able to install it 
without much hazzles (using Debian Etch and installed libxerces27-dev). 
Besides running make (as described by readme.txt), I had to copy the 
liboctavexml.o and liboctavexml.so into /lib/.
Maybe, this (or an alternative solution) should be mentioned in 
readme.txt, too.

Then, running "make runtests" started octave with this warning
> Parsing this format is not supported (yet).
> warning: function name `runtests' does not agree with function file

> testing xml_load

I did not investigate, why this warning occurred, I just ignored it.


Next, I tried to test it on the example file '2003-12 
Schema/example/Example aECG.xml'  in this zip.file:
http://hl7.org/library/committees/rcrim/annecg/aECG%20Release%201%20Schema%20and%20Example%2Ezip

and got the following results:


octave2.1:3> fn = '/home/schloegl/projects/scphl7aecg/2003-12 
Schema/example/Example aECG.xml';
octave2.1:4> fid =fopen(fn,'r');
octave2.1:5> s = char(fread(fid,[1,inf],'char'));
octave2.1:6> fclose(fid);
octave2.1:7> H2 = xml_parseany(s);
Parsing this format is not supported (yet).


xml_parse and xml_load result in a segmentation fault of Octave, each.

octave2.1:6> H3 = xml_parse(s);
octave2.1:8> H1 = xml_load(fn);
warning: An exception occurred! Type:RuntimeException, Message:Warning: 
The primary document entity could not be opened. 
Id=../schema/PORT_MT020001.xsd at line: 0
error: Exception while parsing
panic: Segmentation fault -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete
Segmentation fault


Of course, I'm curious what the problem is, and whether there is a 
solution.


Viele Grüsse,
