How can I ignore the DTD declaration when parsing file with XOM xml library. My file has the following line : <?xml version="1.0"?> <!DOCTYPE BlastOutput PUBLIC "-//NCBI//NCBI BlastOutput/EN" "NCBI_BlastOutput.dtd"> //rest of stuff here And when I try to build() my document I get a filenotfound exception for the DTD file. I know I don't have this file and I don't care about it, so how can it be removed when using XOM? Here is a code snippet: public BlastXMLParser(String filePath) { Builder b = new Builder(false); //not a good idea to have exception-throwing code in constructor try { _document = b.build(filePath); } catch (ParsingException ex) { Logger.getLogger(BlastXMLParser.class.getName()).log(Level.SEVERE,"err", ex); } catch (IOException ex) { // } private Elements getBlastReads() { Element root = _document.getRootElement(); Elements rootChildren = root.getChildElements(); for (int i = 0; i < rootChildren.size(); i++) { Element child = rootChildren.get(i); if (child.getLocalName().equals("BlastOutput_iterations")) { return child.getChildElements(); } } return null; } } I get a NullPointerException at this line: Element root = _document.getRootElement(); With the DTD line removed from the source XML file I can successfully parse it, but this is not an option in the final production system.
