Subject [jira] [Updated] (TIKA-1070) StackOverflow error in org.apache.tika.sax.ToXMLContentHandler$ElementInfo.getPrefix(ToXMLContentHandler.java:58)
Date Thu, 31 Jan 2013 11:57:12 GMT

     [ https://issues.apache.org/jira/browse/TIKA-1070?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Dietmar Glachs updated TIKA-1070:
---------------------------------

    Description: 
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!
