Andreas Veithen commented on AXIOM-478:
---------------------------------------
> LU Jie added a comment on 13/Jan/16 to confirm your previous fix works,
> thanks!
No, her comment on 13/Jan/16 was in response to advice I gave that works with
the existing 1.2.17 release. I was requesting feedback on the issue she
described on 19/Jan/16 and which is fixed in 1.2.18-SNAPSHOT.
> But seems there is another issue(AXIOM-288) in this thread on 19/Jan/16, I am
> not sure about this. If you are ok with AXIOM-288, I think we are ok to go
> for a new release.
No, AXIOM-288 was already implemented in 1.2.15. The problem that will be fixed
by the upcoming 1.2.18 release is that the getTextAsStream method didn't use
the enhancement introduced by AXIOM-288 in the correct way.
> Solution for parsing large XML

> Key: AXIOM-478
> URL: https://issues.apache.org/jira/browse/AXIOM-478
> Project: Axiom
> Issue Type: Question
> Reporter: LU Jie
>
> This is LU Jie from IBM. We use axiom to parse Atom in our project.
> One of our CMIS API will attach file content to the XML. If the file size is
> large, we will get a large atom.
> If we use Entry.getExtension(QName) to parse the content, it will allocate a
> large memory(around 5-6 times of the file size).
> We need you help to clarify if we can use DOM-like API of axiom to get the
> text of a certain element as stream. That is without allocating a large
> object in memory.
> Or is there an alternative solution for this use case?
> We DO know that we can use pull-parser to parse the XML as stream. But we
> need help to investigate if axiom has already provided an API or solution to
> avoid writing parser by ourselves.
> Here's the sample XML. We need to parse the text of cmisra:base64 element:
