Klemens Dickbauer commented on TIKA-2919:
-----------------------------------------
Thanx for the quick response!
Embarassing for me - i just typed the rough design of subclassing the handler
for some extra file writing. I double-checked if i really had called the super
class startElement and endElement methods and really, in this scenario with the
two divs there was an error on my side, i didn't call the second startElement
method because it had the same name as its parent. Fixed it and the NPE
vanished. Sorry for the premature report. Will close now.
> NullPointerException when parsing PDF with OCR and ToXMLContentHandler

> Key: TIKA-2919
> URL: https://issues.apache.org/jira/browse/TIKA-2919
> Project: Tika
> Issue Type: Bug
> Components: handler, ocr
> Affects Versions: 1.21
> Reporter: Klemens Dickbauer
> Priority: Major
>
> When parsing a pdf document the handler creates a structure (and fires
> appropriate SAX exents) that each page is wrapped into two <div> elements.
> The outer one of these has no parent element, so when the subsequent
> endElement method is called for "html", a NPE occurs when
> currentElement.parent is referenced:
> {code:java}
> java class ToXMLContentHandler:
> public void endElement(String uri, String localName, String qName) throws
> SAXException {
> if (this.inStartElement) {
> this.write(" />");
> this.inStartElement = false;
> } else {
> this.write("</");
> this.write(qName);
> this.write('>');
> }
> this.namespaces.clear();
> this.currentElement = this.currentElement.parent;
> }
> {code}
