----------------------------------------------------------------
A snapshot version (1.2.18-SNAPSHOT) containing the fix is available. You can
pull it from the Maven snapshot repository at
https://repository.apache.org/content/repositories/snapshots/ or download the
binary distribution at
https://builds.apache.org/job/axiom-1.2.x/lastStableBuild/org.apache.ws.commons.axiom$distribution/.
Note that for this to work it is mandatory to close the Reader returned by
getTextAsStream before accessing other nodes in the tree.
Please let me know if this solves the issue.

> 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:
