----------------------------------
None of our XML gurus have spotted a problem with this, so I've gone ahead and
applied it (with a doc tweak) in r1496507, thanks!
> StackOverflow error in

> Key: TIKA-1070
> URL: https://issues.apache.org/jira/browse/TIKA-1070
> Project: Tika
> Issue Type: Bug
> Components: parser
> Affects Versions: 1.2, 1.3
> Environment: Java
> Reporter: Dietmar Glachs
> Attachments: ToXMLContentHandler.java.patch
>
>
> The error occurs when parsing big "XLS" files and is caused by the
> ElementInfo stored in "currentElement".
> Each time a new element is started (method startElement) the current elment
> is newly overwritten with
> currentElement = new ElementInfo(currentElement, namespaces);
> where the existing element is used as the parent element. Since the
> currentElement is not reset to the parent element after finishing the element
> (method: endElement) the method getPrefix recursively traverses the parents
> and finally causes the StackOverFlowError
> For my understanding: something like:
> currentElement = currentElement.parent;
> in the endElement method solves the issue!
> Best
