Clarification on the behavior of the text handler

Hi there!

I wanted to clarify on the behavior of the text handler.

Below is the description for the XML_SetCharacterDataHandler API:
------------------------------------------------------------------------
The string your handler receives is NOT zero terminated. You have to
use the length argument to deal with the end of the string. A single
block of contiguous text free of markup may still result in a sequence
of calls to this handler. In other words, if you're searching for a
pattern in the text, it may be split across calls to this handler.
------------------------------------------------------------------------

Lets say that I am passing the complete XML document to the XMLParse()
API in a single shot. So If I register a character data handler for
handling the element data then would I be getting the complete element
text data in a single call to my registered text handler. In other
words, can I safely assume that the first call to the text handler
routine would contain the complete text data?. Even when I pass the
complete XML document to the XMLParse() in a single shot, can the text
data be split across the calls to the data handler?.

Any inputs in this regard would be helpful.
