Export to html from docx

Hi everyone,

To continue my last post: http://www.docx4java.org/forums/xhtml-import-f28/insert-an-altchunk-within-a-table-cell-t1890.html?sid=8e1c49627334cb2731ae2f04a7792c98&sid=8e1c49627334cb2731ae2f04a7792c98#p6527.

After I import html into docx, I want to be able to export this part from docx to html. I wrapped the code in sample and have the code below:

Code: Select all: public class AltChunkAddOfTypeHtml { private static ObjectFactory factory; private final static String inputfilepath = System.getProperty("user.dir") + "/test.docx"; public static void main(String[] args) throws Exception { WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage .createPackage(); MainDocumentPart mdp = wordMLPackage.getMainDocumentPart(); factory = Context.getWmlObjectFactory(); Tbl table = factory.createTbl(); Tr tableRow = factory.createTr(); Tc tableCell = factory.createTc(); wordMLPackage.getMainDocumentPart().addObject(table); String xhtml = "<html><head><title>Import me</title></head><body><p>Hello World!This is the html code converted into docx!!!</p><b>tested by david</b></body></html>"; ; mdp.addAltChunk(AltChunkType.Xhtml, xhtml.getBytes(), tableCell); tableRow.getContent().add(tableCell); table.getContent().add(tableRow); // Round trip wordMLPackage = mdp.convertAltChunks(); wordMLPackage.save(new java.io.File(inputfilepath)); List<Object> tableCells = getAllElementFromObject( wordMLPackage.getMainDocumentPart(), Tc.class); System.out.println(tableCells.size()); /* only one tc in wordMLPackage */ List<Object> paragraphsInTc = getAllElementFromObject( tableCells.get(0), P.class); System.out.println(paragraphsInTc.size()); System.out.println("Ready to create html."); WordprocessingMLPackage wordMLPackage2 = WordprocessingMLPackage .createPackage(); for (Object o : paragraphsInTc) { wordMLPackage2.getMainDocumentPart().addObject(o); } HTMLSettings htmlSettings = Docx4J.createHTMLSettings(); htmlSettings.setWmlPackage(wordMLPackage2); OutputStream os; os = new FileOutputStream(new java.io.File( System.getProperty("user.dir") + "/sample.html")); System.out.println("Creating html."); Docx4J.toHTML(htmlSettings, os, Docx4J.FLAG_EXPORT_PREFER_XSL); } private static List<Object> getAllElementFromObject(Object obj, Class<?> toSearch) { List<Object> result = new ArrayList<Object>(); if (obj instanceof JAXBElement) obj = ((JAXBElement<?>) obj).getValue(); if (obj.getClass().equals(toSearch)) result.add(obj); else if (obj instanceof ContentAccessor) { List<?> children = ((ContentAccessor) obj).getContent(); for (Object child : children) { result.addAll(getAllElementFromObject(child, toSearch)); } } return result; } }

It's working for me and below is the html I got:

Code: Select all: <?xml version="1.0" encoding="utf-8"?><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships"><head><meta content="text/html; charset=utf-8" http-equiv="Content-Type" /><style></style><script type="text/javascript"></script></head><body>  <div style="color:red">TO HIDE THESE MESSAGES, TURN OFF debug level logging for org.docx4j.convert.out.common.writer.AbstractMessageWriter </div> <div class="document"> <p class="Normal DocDefaults " style="text-align: left;position: relative; margin-left: 0in;margin-bottom: 0in;"><span class="DefaultParagraphFont " style="font-weight: normal;color: #000000;font-style: normal;font-size: 11.0pt;;font-family: Calibri;">Hello World!This is the html code converted into docx!!!</span></p> <p class="Normal DocDefaults " style="text-align: left;position: relative; margin-left: 0in;margin-bottom: 0in;"><span class="DefaultParagraphFont " style="font-weight: bold;color: #000000;font-style: normal;font-size: 11.0pt;;font-family: Calibri;">tested by david</span></p></div>  </body></html>

As I need to save this html code into database, is there anyway to make the converted html clean? Just like before it was imported into docx? Like this:

Code: Select all: <html><head><title>Import me</title></head><body><p>Hello World!This is the html code converted into docx!!!</p><b>tested by david</b></body></html>

Or maybe is there a better solution to do the convert from docx to html?
Thanks in advance.

Solved by reading paragraphs and runs from word, then add html tags. Put the code below:

Code: Select all: /** * Convert the description in table cell back into html code to be saved into database * * @param tc * @return */ private String convertTcToHtml(Tc tc) { StringBuilder sb = new StringBuilder(); sb.append("<html><body>"); List<Object> paragraphs = getAllElementFromObject(tc, P.class); if (paragraphs == null || paragraphs.size() == 0) { return null; } /* Description exported from alm only has one paragraph in word. */ List<Object> runs = getAllElementFromObject(paragraphs.get(0), R.class); addRunsToHtmlStringBuffer(sb, runs); /* If user modify description in word it may generate more paragraphs in word. */ if (paragraphs.size() > 1) { sb.append(" "); for (int i = 1; i < paragraphs.size(); i++) { List<Object> moreRuns = getAllElementFromObject(paragraphs.get(i), R.class); addRunsToHtmlStringBuffer(sb, moreRuns); /* Every paragraph should be starting from a new line */ sb.append(" "); } } sb.append("</body></html>"); return sb.toString(); } /** * Add Texts of a list of Runs to the html string builder * * @param sb * @param runs */ private void addRunsToHtmlStringBuffer(StringBuilder sb, List<Object> runs) { if (runs != null && runs.size() > 0) { for (Object r : runs) { R run = (R) r; List<Object> brs = getAllElementFromObject(run, Br.class); if (brs != null && brs.size() > 0) { LOGGER.info("BR:"); sb.append("<br/>"); } /* One run usually has one text */ List<Object> texts = getAllElementFromObject(run, Text.class); if (texts != null && texts.size() > 0) { StringBuilder text_sb = new StringBuilder(); for (Object t : texts) { Text text = (Text) t; text_sb.append(text.getValue()); } String htmlText = replaceWithHtmlCharacters(text_sb.toString()); if (run.getRPr() != null && run.getRPr().getB() != null && (run.getRPr().getB().isVal())) { LOGGER.info("Bold Text:"); sb.append("<b>"); sb.append(htmlText); sb.append("</b>"); } else { LOGGER.info("Normal Text:"); sb.append(htmlText); } } } } } /** * Replace ", <, > with html special charactors * * @param text * @return */ private String replaceWithHtmlCharacters(String text) { text = text.replace("\"", """); text = text.replace("<", "<"); text = text.replace(">", ">"); return text; }

Hi David, Glad you got it doing what you wanted. A couple of years ago I customised the HTML export for a customer to produce minimalist output, but that code is not in docx4j per se. cheers .. Jason
