Other people on this list pointed out that if you're creating your own error
handler, you have to deal with your error handler being called multiple
times for a single error. So here is my question:
How can I safely gather the entire error message and output it to a log file
in one line?
What I have done to work around this so far is to store all the pieces of
the error message in a static buffer (static char *) until I receive the
piece (string) that ends in a newline character, then I copy the buffer to
my logging function (also prepending "libxml:" to it). Therefore, I'm
making the assumption that I will eventually get a string that ends in a
newline character. I'm not sure if that's a safe assumption.

Registering the callback:
xmlSetGenericErrorFunc(NULL, (xmlGenericErrorFunc)libxml_log);
Defining the callback function:
void libxml_log(void *ctx, const char *msg, ...) { }
