[jira] [Commented] (OLINGO-73) Woodstox parser fails for big files sometimes

["Aki Yoshida (JIRA)" <ji...@apache.org>]

Aki Yoshida commented on OLINGO-73:
-----------------------------------

hi,
As far as I know (tried to find the spec statement but couldn't find it), this is not a bug in the parser and it's part of optimization. There is no requirement by the parser to return a single characters event for a character sequence appearing within xml.

so you need to check the event type before calling methods like nextTag that are only allowed to be called at an appropriate event.
regards, aki

> For some big xml files the woodstox parser which is a transitive dependency of cxf fails with the exception: "Found characters or cdata event when not expected"
> This happens because a previous call of getText() doesn´t deliver the whole text but only a fraction. So when we call nextTag() the parser throws the exception because there is still character data on the buffer. This issue does only appear with big xml files and happens randomly within the document altough always at the same element.
> So maybe this is a woodstox bug. We can implement a workaround by calling getText() as long as there is still character data left.
