The problems were twofold:
1) I was not correctly allowing for split chunks (multiple data() calls).
2) I need to have table data as it is, now.
Almost fixed. But, the kids are up and it's time for breakfast...

That sounds like the right approach to me (and I'm an expert because I
took a compilers class 15 years ago and we used the Dragon book.) :-)

No, there is no guarantee that the string will be non-empty (that goes
down to the underlying XML library). Again, make sure that you set
value = at the start event, and then process value at the
corresponding end event.

Make sure you blank the string at the start tag.

Here's what's in the Traffic Manager:
void FGTrafficManager::data (const char * s, int len)
{
string token = string(s,len);
if (( token.find( ) == string::npos
(token.find('\n')) == string::npos))
{

As far as I can tell, there is no SimGear-devel list, so I'm asking
this here.
I'm probably going to toy with EasyXML for a C++ side project I'm
working on - and if that goes well, perhaps think about using it with
JSBSim as well. I am guessing that I ought to be able to grab the

I looked at the code for readxml and the path is simply a descriptor for
the document being parsed (ie file name) and does not effect the parsing.
The new question is how to cast? the char * to an istream?

Hi,
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

I figured out the what you mention. The part that confuses me is how to
put the data from the xml file in a desired location. For example if I
have the xml document:
...
vehicle
id1/id
lon-128.553223/lon
lat54.233123/lat
/vehicle
...
How does id, lon, lat initialize the variables int
