byte[] bytes = Files.readAllBytes(Paths.get("E:\\\\pdf\\\\aaa\\\\html\\\\text.txt").normalize()); String text = IOUtils.toString(bytes); String xml = text.substring(text.indexOf("<tbody>")); InputSource inputXML = new InputSource( new StringReader( xml ) ); XPath xPath = XPathFactory.newInstance().newXPath(); NodeList nodes = (NodeList) xPath.evaluate("/tbody/tr", inputXML, XPathConstants.NODESET); int length = nodes.getLength(); Path file = Paths.get("E:\\\\pdf\\\\aaa\\\\html\\\\out.txt"); try (BufferedWriter writer = Files.newBufferedWriter(file, Charset.defaultCharset(), StandardOpenOption.CREATE)) for (int i = 0; i < length; i++) Node node = nodes.item(i); NodeList childList = (NodeList) xPath.evaluate("td", node, XPathConstants.NODESET); for (int j = 0; j < childList.getLength(); j++) Node child = childList.item(j); String content = child.getTextContent(); //System.out.print(content); writer.write(content); if (j <childList.getLength() - 1) writer.write("\\t"); writer.newLine();
