XML file to RTF and PDF conversion

For such an XML document, we must convert it into a PDF format to create an XSL-FO file to define the conversion to each Element and Value format. We build the XSL-FO file Test.xsl as follows:

cardiac feature srs < XSL: APPLY-TE Mplates /> <

! - ========================================00 1. Intruction 1.1 Objective 1.2 Scope 1.3. Responsibilities

Font-weight = "bold" space-after = "5mm" margin-left = "5mm"> 1.4. References 1.5. definitions, acronyms, and abbreviations < XSL: Text> Term definition < / fo: block>

2. General Description 2.1. Feature Name 2.1.1. Feature Summary 2.1.2. Feature Breakdown 2.2. feat Ure Requirements 2.3. Feature Interactions 3. String resources English string Resource ID RQMT < / fo: block> <

XSL: for-each select = "strresource"> The syntax of its specific XSL-FO file format can refer to Some other information. After the establishment of this file, we can use some of the interfaces provided by FOP to convert. FOP provides XML-> FO, XML-> PDF, FO-PDF, Obj-> fo, Obj- > PDF conversion interface. We here use XML-> PDF as an example, the rest can refer to the corresponding DEMO in the FOP package.

public class ExampleXML2PDF {public void convertXML2PDF (File xml, File xslt, File pdf) throws IOException, FOPException, TransformerException {Driver driver = new Driver (); Logger logger = new ConsoleLogger (ConsoleLogger.LEVEL_INFO); driver.setLogger (logger); MessageHandler.setScreenLogger (logger); // Setup Renderer (output format) driver.setRenderer (Driver.RENDER_PDF); // Setup output OutputStream out = new java.io.FileOutputStream (pdf); try {driver.setOutputStream (out); // Setup XSLT TransformerFactory factory = TransformerFactory.newInstance (); Transformer transformer = factory.newTransformer (new StreamSource (xslt)); // Setup input for XSLT transformation Source src = new StreamSource (xml); // Resulting SAX events (the Generated fo) Must Be Piped THROUGH to FOP RESULT RES = New Saxr Esult (Driver.getContentHandler ()); // Start Xslt Transformation and Fop Processing Transformer.Transform (src, res);} finally {out.close ();}} public static void main (string [] args) {TRY { System.out.println ("FOP EXAMPLEXML2PDF / N"); System.out.Println ("preplay ..."); // setup Director File Basedir = new file ("."); File outdir = new file (Basedir , "out"; outdir.mkdirs (); // setup input and output files file xmlfile = new file (basedir, "test.xml"); file xsltfile =

New file (Basedir, "Test.xsl"); file pdffile = new file (Outdir, "Test.pdf"); system.out.println ("Input: XML (" XMLFile ")"); system.out .println ("Stylesheet:" xsltfile; system.out.println ("Output: PDF (" PDFFILE ")"); system.out.println (); system.out.println ("Transforming ... "); ExampleXML2PDF app = new ExampleXML2PDF (); app.convertXML2PDF (xmlfile, xsltfile, pdffile); System.out.println (" Success ");!} catch (Exception e) {System.err.println (ExceptionUtil.printStackTrace (e)); system.exit (-1);}}} This easily implements XML documentation to the conversion of PDF documents. If you use it in a servlet of WebService, you want to generate PDF transfer from XML files. PDF files do not generate by viewers, we can implement them as follows:

public class FOPServlet extends HttpServlet {public static final String FO_REQUEST_PARAM = "fo"; public static final String XML_REQUEST_PARAM = "xml"; public static final String XSL_REQUEST_PARAM = "xsl"; public void doGet (HttpServletRequest request, HttpServletResponse response) throws ServletException {try {String Xmlparam = getServletContext (). GetRealPath ("Web-INF / DOC / XML / Test.xml"); String Xslparam = GetServletContext (). GetRealPath ("Web-INF / DOC / XSL / TEST.XSL"); if (!! (xmlParam = null) && (xslParam = null)) {XSLTInputHandler input = new XSLTInputHandler (new File (xmlParam), new File (xslParam)); renderXML (input, response);} else {PrintWriter out = response. getwriter (); out.println ("
