Is there a tutorial or can someone give or direct me to a simple example on how to use easyxml? I am trying to work my way through props_io.cxx but it is not an easy introduction.
Do you want to work with properties or raw, low-level XML? Properties provide a higher level of abstraction that hides most of the messy XML details from you. If you do want to work with low-level XML, look at the documentation comments in simgear/xml/easyxml.hxx for details. Essentially, you create a class that extends XMLVisitor, then pass it to the readXML function as an argument, i.e.
MyVisitor visitor;
try {
readXML("foo.xml", visitor);
} catch (const sg_io_exception &e) {
// deal with the error
}All the best,
David
