  Subject: [Expat-discuss] Event callbacks for every Tag


  Hi, I am new user of the expat library. My application requires different code to be run on different xml tags when they are found and on the fly. I have learned expat is event driven, but only one function is calledback on every tag found (endElement). My question is, can expat callback different functions based on tag found, meaning a unique callback for every tag. Is that possible?
  Please help me out

You can do something like that:
In the unic element_end callback, you multiplex your different callbacks based on the tag.

static void XMLhndl_ElementEnd(void *userData, const char *strElement)
 {
 if (strcmp(strElement,"TAG1")==0)
  {
  // call your callback for TAG1 here 
  return;
  }

 if (strcmp(strElement,"TAG2")==0)
  {
  // call your callback for TAG2 here 
  return;
  }

}
