UnmarshallFromTemplate cannot replace Header's Text

[yugikhoi]

Hi,

I am new to this forum and very impressive with all docx4j work. I tried to replace text in MSWord document by UnmarshallFromTemplate.java (887), everything is just perfect. However, when I add a header and put a variable there, it is not working. I think it got problems with getting Relatioship Part or something like that but don't know how to fix (I keep exactly sample code and your docx file). Can anyone have exp. help me with your coding? Thanks a lot.

You're right, the sample doesn't do that.

It applies the pattern

Code: Select all

         String xml = XmlUtils.marshaltoString(wmlDocumentEl, true);                 
         Object obj = XmlUtils.unmarshallFromTemplate(xml, mappings);


to the main document part (document.xml) only.

But you can do the same thing to your header and footer parts. You can access them by the wmlPkg's getDocumentModel() method.

Thanks for your respond however i am just beginner on docx4j so I do not understand how to achieve what your said. Can you give me sample code for that? Thanks.

Which bit are you having trouble understanding?

Perhaps the sample HeaderFooterList will help. The guts of it:

                List<SectionWrapper> sectionWrappers = wordMLPackage.getDocumentModel().getSections();
               
                for (SectionWrapper sw : sectionWrappers) {
                        HeaderFooterPolicy hfp = sw.getHeaderFooterPolicy();
                       
                        System.out.println("\n\nSECTION  \n");
                       
                        System.out.println("Headers:");
                        if (hfp.getFirstHeader()!=null) System.out.println("-first");
                        if (hfp.getDefaultHeader()!=null) System.out.println("-default");
                        if (hfp.getEvenHeader()!=null) System.out.println("-even");
                       
                        System.out.println("\nFooters:");
                        if (hfp.getFirstFooter()!=null) System.out.println("-first");
                        if (hfp.getDefaultFooter()!=null) System.out.println("-default");

From the HeaderFooterPolicy object, you can get the relevant HeaderPart or FooterPart:

        /**

         *  also the same as the default one...

        public HeaderPart getOddHeader() {

        public FooterPart getOddFooter() {

I'm trying to do the exact same thing...

But when I find my header, and try to marshal it to a string I get this exception:

Code: Select all

        javax.xml.bind.JAXBException: class org.docx4j.openpackaging.parts.WordprocessingML.HeaderPart nor any of its super class is known to this context.
   at com.sun.xml.internal.bind.v2.runtime.JAXBContextImpl.getBeanInfo(JAXBContextImpl.java:540)
   at com.sun.xml.internal.bind.v2.runtime.XMLSerializer.childAsRoot(XMLSerializer.java:460)

   at org.docx4j.XmlUtils.marshaltoString(XmlUtils.java:406)
   at org.docx4j.XmlUtils.marshaltoString(XmlUtils.java:336)


The relevant code looks like this:

Code: Select all


         for (SectionWrapper sw : sectionWrappers) {
               HeaderFooterPolicy hfp = sw.getHeaderFooterPolicy();
               if (hfp != null) {
                  HeaderPart headerPart = hfp.getDefaultHeader();
                  if (headerPart != null) {
                     //xml --> string
                     xml = XmlUtils.marshaltoString(headerPart, true);      


Any clues?

Thanks!

At a glance, looks like you need to call the getJAXBElement() method in that last line:

Code: Select all

xml = XmlUtils.marshaltoString(headerPart.getJAXBElement(), true);

Yes, of course...thanks for spotting that!
