[Expat-discuss] extracting value other than element and attribute

[Nick MacDonald]

To get the start and the end of the elements, you use callbacks, which
in my code are called startElement and endElement:
        XML_SetElementHandler(parser, startElement, endElement);
This is also where you get to know the parameters on the elements,
such as your id="1001"

But to get the data inside the elements, you need the following, which
calls a callback elementText in my case:
        XML_SetCharacterDataHandler(parser, elementText);

void XMLCALL elementText(
  void*       userData,
  const char*  text,
  int          len
);

NOTE you may get more than one of these callbacks, and YOU have to
handle the concatenation.  (This can occur depending on line breaks,
and special embedded content, such as &  and the like.  I mention
this, as it has been a stumbling block and often seems to surprise
others who write to the list about it.)

Good luck,
  Nick
