Java change and move non-standard XML file

Question

I am using a third party application and would like to change one of its files. The file is stored in XML but with an invalid doctype. When I try to read use a it errors out becuase the doctype contains "file:///ReportWiz.dtd" (as shown, with quotes) and I get an exception for cannot find file. Is there a way to tell the docbuilder to ignore this? I have tried setValidate to false and setNamespaceAware to false for the DocumentBuilderFactory. The only solutions I can think of are copy file line by line into a new file, omitting the offending line, doing what i need to do, then copying into another new file and inserting the offending line back in, or doing mostly the same above but working with a FileStream of some sort (though I am not clear on how I could do this..help?) DocumentBuilderFactory docFactory = DocumentBuilderFactory .newInstance(); docFactory.setValidating(false); DocumentBuilder docBuilder = docFactory.newDocumentBuilder(); Document doc = docBuilder.parse(file); JavaScript questions and answers, JavaScript questions pdf, JavaScript question bank, JavaScript questions and answers pdf, mcq on JavaScript pdf, JavaScript questions and solutions, JavaScript mcq Test , Interview JavaScript questions, JavaScript Questions for Interview, JavaScript MCQ (Multiple Choice Questions)

Answer 1

Tell your DocumentBuilderFactory to ignore the DTD declaration like this: docFactory.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false); See here for a list of available features. You also might find JDOM a lot easier to work with than org.w3c.dom: org.jdom.input.SAXBuilder builder = new SAXBuilder(); builder.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false); org.jdom.Document doc = builder.build(file);
