docx4j JaxbValidationEventHandler openpackaging.parts.JaxbXmlPart

docx4j printed an exception(not throwed ) when just loading docx file . The program continued, but, it seems docx4j cann't handle ppr and rpr tags in /word/document.xml

test code:

Code: Select all

public static void main(String[] args)throws Exception {
        logger.info("size is  {}", DocxUtil.getAllElementFromObject(docxTemplate.getMainDocumentPart(), PPr.class).size());  // returns 0!!
        logger.info("size is  {}", DocxUtil.getAllElementFromObject(docxTemplate.getMainDocumentPart(), RPr.class).size());  // returns 0!!
        logger.info("size is  {}", DocxUtil.getAllElementFromObject(docxTemplate.getMainDocumentPart(), Text.class).size());
        logger.info("size is  {}", DocxUtil.getAllElementFromObject(docxTemplate.getMainDocumentPart(), P.class).size());
        logger.info("size is  {}", DocxUtil.getAllElementFromObject(docxTemplate.getMainDocumentPart(), R.class).size());

This looks like it is normal mc:AlternateContent processing, in this case containing w:pict:

Thanks Jason.

#1
Indeed, the document.xml does contains w:pict. Is there anyway docx4j could handle w:pict ?

#2
And there's another question in the post before, I coun't get PPr Object or RPr Object directly from main doc part, is it some kind of restriction or bad coding ?
By the way, since I can get R.class object through the same method 'R r = (R)DocxUtil.getAllElementFromObject(...)' , and then using RPr rpr = (RPr)r.getRPr() dose returns it's value. Is it means we just couldn't get RPr.class object from main document part?

Code: Select all

        logger.info("sieze is  {}", DocxUtil.getAllElementFromObject(docxTemplate.getMainDocumentPart(), PPr.class).size());  // returns 0
        logger.info("sieze is  {}", DocxUtil.getAllElementFromObject(docxTemplate.getMainDocumentPart(), RPr.class).size());  // returns 0
        logger.info("sieze is  {}", DocxUtil.getAllElementFromObject(docxTemplate.getMainDocumentPart(), Text.class).size());
        logger.info("sieze is  {}", DocxUtil.getAllElementFromObject(docxTemplate.getMainDocumentPart(), P.class).size());
        logger.info("sieze is  {}", DocxUtil.getAllElementFromObject(docxTemplate.getMainDocumentPart(), R.class).size());

Docx4j does handle w:pict. It generally doesn't preserve mc:alternateContent (though it does in some particular cases); it generally selects the fallback: https://github.com/plutext/docx4j/blob/ ... essor.xslt So assuming your w:pict is in there, that's what will be retained.

Regarding your question #2, the reason is that PPr and RPr aren't in the respective content lists which your code relies on. See https://github.com/plutext/docx4j/blob/ ... P.java#L82
