HTML merge with docx issue

[tomHorsa]

Good morning,

I am merging an HTML with a docx. The program has always worked, but with the new docx the program no longer works correctly. The generated docx is generated with unreadable content, even if in reality, when you open the document with word, it is recovered. Why?

My code was:

FileInputStream docxTemplate = new FileInputStream(path + docxTemplateName);
File htmlFile = new File(path + htmlFileName);
String outpuFileName = path + htmlFileName + "_FINALE.docx";
htmlToWordTemplate(docxTemplate,htmlFile,outpuFileName);



private static void htmlToWordTemplate( FileInputStream docxTemplate,File htmlFile,String outputFileName) throws Exception {

WordprocessingMLPackage f = WordprocessingMLPackage.load(docxTemplate);
XHTMLImporterImpl XHTMLImporter = new XHTMLImporterImpl(f);
f.getMainDocumentPart().getContent().addAll(XHTMLImporter.convert( htmlFile, null) );
ByteArrayOutputStream out = new ByteArrayOutputStream();
f.save(out);
out.flush();
try(OutputStream outputStream = new FileOutputStream(outputFileName)) {
out.writeTo(outputStream);
}

}

Your merge_error.docx has @mc:Ignorable containing w16sdtfl but does not declare that namespace.

You need to upgrade from docx4j 8.3.11 to docx4j 8.3.14. You might think you are using 8.3.14 already, but not according to the comment docx4j inserted in your document.xml: Modified by docx4j 8.3.11 (Apache licensed) using REFERENCE JAXB in Eclipse Adoptium Java.

You can use mvn to figure out what is happening; see for example https://stackoverflow.com/a/57228188/1031689
