SdtContentBlock to html

[laurenquintanilla]

Hello,

Is it possible to convert just the content from a SdtContentBlock to html? Instead of converting the entire document to html and trying to parse out the pieces from various content controls.

Hi Lauren

There's a fairly straightforward hack: you can temporarily replace the main document part's content list with just the content of interest (in this case your SdtContentBlock's), perform the conversion, then swap it back again.

Alternatively, HtmlExporterNonXSLT contains:

Syntax: [ Download ] [ Hide ] [ Select ] [ Expand ]

Syntax: [ Download ] [ Show ]

Using java Syntax Highlighting

        public org.w3c.dom.Document export(Object blockLevelContent, String cssClass, String cssId) {
                HTMLConversionContext conversionContext =
                                new HTMLConversionContext(htmlSettings, null, null);
        Document document = XmlUtils.neww3cDomDocument();      
    Element parentNode = document.createElement("div");
    AbstractVisitorExporterGenerator<HTMLConversionContext> generator = null;
        if (cssClass!=null) {
                parentNode.setAttribute("class", cssClass);
        }
        if (cssId!=null) {
                parentNode.setAttribute("id", cssId);
        }
        document.appendChild(parentNode);
        generator = HTMLExporterVisitorGenerator.GENERATOR_FACTORY.
                        createInstance(conversionContext, document, parentNode);
        new TraversalUtil(blockLevelContent, generator);
                return document;
        }      

 

Parsed in 0.016 seconds, using GeSHi 1.0.8.4

but the Javadoc warns of cases where it might not work.

Trying to do the 'hack', but when I log out the output stream, I get an empty body. Output stream just has some placeholders and header/footer info.
Do you see anything obvious wrong here?

Object bodyContent = wordMLPackage.getMainDocumentPart().getJAXBNodesViaXPath(String.format(contentXpath, theAttribute), false);
//bodyContent is size 1 ArrayList with one populated SdtContentBlock
OutputStream os = new ByteArrayOutputStream();
HTMLSettings htmlSettings = Docx4J.createHTMLSettings();
wordMLPackage.getMainDocumentPart().getContent().clear();
wordMLPackage.getMainDocumentPart().getContent().addAll((Collection<?>) bodyContent);
htmlSettings.setWmlPackage(wordMLPackage);
Docx4J.toHTML(htmlSettings, os, Docx4J.FLAG_EXPORT_PREFER_XSL);

Nevermind - just found it

[laurenquintanilla]

do you know where to set the property to remove this from the generated html?

TO HIDE THESE MESSAGES, TURN OFF debug level logging for org.docx4j.convert.out.common.writer.AbstractMessageWriter


I tried the following:
Docx4jProperties.setProperty("org.docx4j.convert.out.common.writer.AbstractMessageWriter", false);
Docx4J.toHTML(htmlSettings, os, Docx4J.FLAG_EXPORT_PREFER_XSL);

but I still get that message in my html

Configure logging; see the notes at https://github.com/plutext/docx4j/blob/ ... g4j.xml#L5

If you do use that log4j config, adjust line 115: https://github.com/plutext/docx4j/blob/ ... j.xml#L115
