[Octave-bug-tracker] [bug #45951] Add "xmlread" to core Octave or replace the one in io package

[Pantxo Diribarne]

Follow-up Comment #7, bug #45951 (project octave):

>> Why is classdef required, or so advatageous, for reading XML?

I don't know of another way to have "object.method (args)" syntax (as in ML,
see e.g. [1]) in the interpreter ... well except for Java objects.

I am also completely ignorant about xml parsers *and* Java. Simply saying that
wrapping all (very many) methods from libxml2 to obtain an interface that we
could have using a few lines of code is a waste of time:


function doc = xmlread (fname)
  parser = javaObject ('org.apache.xerces.parsers.DOMParser');
  parser.parse(filename); 
  doc = parser.getDocument;
endfunction
  

Once we have the path to relevant Xerces jar files, as explained in the wiki,
the above is enough to run Matlab examples.

The only problem I had to run examples in [2] is that the returned object has
no "getMethods" method so e.g. "methods (doc)" doesn't work in Octave out of
the box (I used try/catch).
