docx-->html-->docx error

[areindal]

We are converting a docx file to html. To do so we are using the following code:

Code: Select all


          /* CSS reset, see http://itumbcom.blogspot.com.au/2013/06/css-reset-how-complex-it-should-be.html
           *
           * motivated by vertical space in tables in Firefox and Google Chrome.
          
              If you have unwanted vertical space, in Chrome this may be coming from -webkit-margin-before and -webkit-margin-after
              (in Firefox, margin-top is set to 1em in html.css)
             
              Setting margin: 0 on p is enough to fix it.
             
              See further http://www.css-101.org/articles/base-styles-sheet-for-webkit-based-browsers/       
          */
          String userCSS = "html, body, div, span, h1, h2, h3, h4, h5, h6, p, a, img,  ol, ul, li, table, caption, tbody, tfoot, thead, tr, th, td " +
                "{ margin: 0; padding: 0; border: 0;}" +
                "body {line-height: 1;} ";
          htmlSettings.setUserCSS(userCSS);
          
          
          // list numbering:  comment out 1 or other of the following, depending on whether
          // you want list numbering hardcoded, or done using <li>.
          //SdtWriter.registerTagHandler("HTML_ELEMENT", new SdtToListSdtTagHandler());
          htmlSettings.getFeatures().remove(ConversionFeatures.PP_HTML_COLLECT_LISTS);
         
         // output to an OutputStream.      
         OutputStream os;
         if (save) {
            os = new FileOutputStream(inputfilepath + ".html");
         } else {
            os = new ByteArrayOutputStream();
         }
   
         // If you want XHTML output
          //Docx4jProperties.setProperty("docx4j.Convert.Out.HTML.OutputMethodXML", true);
   
         //Don't care what type of exporter you use
   //      Docx4J.toHTML(htmlSettings, os, Docx4J.FLAG_NONE);
         //Prefer the exporter, that uses a xsl transformation
         Docx4J.toHTML(htmlSettings, os, Docx4J.FLAG_EXPORT_PREFER_XSL);
         //Prefer the exporter, that doesn't use a xsl transformation (= uses a visitor)
   //      Docx4J.toHTML(htmlSettings, os, Docx4J.FLAG_EXPORT_PREFER_NONXSL);
   
         if (save) {
            System.out.println("Saved: " + inputfilepath + ".html ");
         } else {
            System.out.println( ((ByteArrayOutputStream)os).toString() );
         }
   
         // Clean up, so any ObfuscatedFontPart temp files can be deleted
         if (wordMLPackage.getMainDocumentPart().getFontTablePart()!=null) {
            wordMLPackage.getMainDocumentPart().getFontTablePart().deleteEmbeddedFontTempFiles();
         }      
         // This would also do it, via finalize() methods
         htmlSettings = null;
         wordMLPackage = null;         
         
       }


After that, we are trying to convert the generated html to docx again this way:

Code: Select all


         WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.createPackage();
           MainDocumentPart wordDocumentPart = wordMLPackage.getMainDocumentPart();
          // String outputfilepath = "c:\\style-example-OUT.docx";
          
           String text = data;
           XHTMLImporter xHTMLImporter = new XHTMLImporterImpl(wordMLPackage);
           
           //Inicio: Registrando fuentes para la conversión           
           RFonts arialRFonts = Context.getWmlObjectFactory().createRFonts();
            arialRFonts.setAscii("Arial");
            arialRFonts.setHint(org.docx4j.wml.STHint.DEFAULT);
            arialRFonts.setHAnsi("Arial");
            XHTMLImporterImpl.addFontMapping("Arial", arialRFonts);
            RFonts timesRFonts = Context.getWmlObjectFactory().createRFonts();
            timesRFonts.setAscii("Times");
            timesRFonts.setHint(org.docx4j.wml.STHint.DEFAULT);
            timesRFonts.setHAnsi("Times");
            XHTMLImporterImpl.addFontMapping("Times New Roman", timesRFonts);           
            //fin regsitrando fuentes
           
           xHTMLImporter.setParagraphFormatting(FormattingOption.CLASS_PLUS_OTHER);
           xHTMLImporter.setRunFormatting(FormattingOption.CLASS_PLUS_OTHER);
           File file = new File(PATH_PRUEBAS+FICHERO_ENTRADA);
           wordMLPackage.getMainDocumentPart().getContent().addAll(xHTMLImporter.convert(file, null));
           //wordDocumentPart.addParagraphOfText("Manipulating Word document with docx4j");
           // Save it
           wordMLPackage.save(new File("C:/pruebas/out.docx"));

         
      }catch(Exception e){
         System.out.print(e.getMessage());
         //   LOGGER.debug(e.getMessage());
      }



and we are getting the following error:

Code: Select all

Can anyone help us to find the cause?

We are using the following libraries:
· docx-ImportXHTML-3.0.0.jar
· docx4j-3.2.2.jar

Thx

The first step would be to examine the contents of the generated XHTML file. It needs to be well-formed XML.
