I apologize for asking the same question, but as per my research it seemed in different context. I know why the error is coming but I failed to eradicate it without looking and following some programming forums. My program goes as follows: I am pinging a url and opening input stream, then that stream is written into an xml file. After that I am using Xpath to extract some information that is further used for some computation. My code is as follows:\[code\] URL u=new URL("url here"); HttpURLConnection con=(HttpURLConnection)u.openConnection(); InputStream is=con.getInputStream(); BufferedInputStream br=new BufferedInputStream(is); File f=new File("data.xml"); if(f.exists())f.delete(); f.createNewFile(); byte data[] = new byte[1024]; int count; FileOutputStream fout = new FileOutputStream(f); while((count = br.read(data,0,1024)) != -1) { fout.write(data, 0, count); } fout.close(); DocumentBuilderFactory dbf=DocumentBuilderFactory.newInstance(); DocumentBuilder db=dbf.newDocumentBuilder(); Document doc=db.parse("data.xml"); XPathFactory factory=XPathFactory.newInstance(); XPath xPath=factory.newXPath(); XPathExpression expr = xPath.compile("//tr/text()"); Object result = expr.evaluate(doc, XPathConstants.NODESET); NodeList nodes = (NodeList) result; for (int i = 0; i < nodes.getLength(); i++) { System.out.println(nodes.item(i).getNodeValue()); }\[/code\]when executing this code I get : White spaces are required between publicId and systemId.Since I am directly writing to the file, where can this white space error possibly occur?
