Subject [jira] [Commented] (TIKA-2919) NullPointerException when parsing PDF with OCR and ToXMLContentHandler
Date Fri, 02 Aug 2019 12:50:00 GMT

Tim Allison commented on TIKA-2919:
-----------------------------------

W00t!  Thank you for closing the loop.  After the slog of the last release, I was less than
entirely thrilled to learn about a new NPE in < 24 hours of the release. 

:P  

Onward!

> 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}
