Stax XML EventReader: What portion of data is returned when parsing large data element

Posted on 2010-11-08

We have a very large content of one data element (over 1000 000 of strings). When we parse with stax we HARACTER event is triggered so that normall around 12 strings  are returned by one event, so we assumed first, there is some parse buffer length there.
Then,  we saw around 6 exceptuions of this rule.
We played around if that might be due to specific data and whitespaces but XML is generated automatically and after removing certin portions the problem appeared elsewhere at parsing

The question is: if stax event parses is faced to large contents what triggers the event and what portion of text we may expect in the returned characters ?

Incidentally, afaik in no implementation of sax or stax is it guaranteed that all the expected text in a characters event will be returned in one call. It's up to the reader to buffer and collect content returned by characters

Does anyone has toher idea if we can control the size of the text read by one event?
