Well, your output is particular to your text event handlers so what you show us does not tell us what were the inputs. If you have two events and you got "abc " and "abocd abdec" (or the trailing spaces from the first appeared on the second and not the first), that would not suprise me. The underlying XML parser is extracting content from a stream of bytes. It makes no guarantee that contiguous text content is delivered in a single event to the handlers. Instead, it consumes as much of the stream as it wants and delivers that and then continues from where it left off in the stream. If it encounters a text node with a large amount of text, it will deliver that in smaller chunks. This undoubtedly makes the processing of the stream slightly harder for the handler as it has to remember where it "was", but this is true of all handlers so not a significant burden. The branches parameter of the xmlEventParse() function does provide a way to mix SAX/event parsing with the easier DOM/node style parsing. D. > > Should it be like that?
