Traverse problem

[lazvegas]

Hello,

I am trying to use a template with my docx4j. In my template I am using a placeholder like

#SessionDate#

but when I traverse the docx it is traversing it like that

#
SessionDate
#

How can I fix it ? Thank you.

[jason]

Sorry, it isn't clear what you are asking here.

Is #SessionDate# a variable you are trying to replace?

Including your code and/or the XML around #SessionDate# might make your question clearer.

Hello I am using thefinal version of docx4j, I attached the template document and
the output of the traverse code.

/**
* To see what parts comprise your docx, try the PartsList sample.
*
* There will always be a MainDocumentPart, usually called document.xml.
* This sample shows you what objects are in that part.
*
* It also shows a general approach for traversing the JAXB object tree in
* the Main Document part.  It can also be applied to headers, footers etc.
*
* It is an alternative to XSLT, and doesn't require marshalling/unmarshalling.
*
* If many cases, the method getJAXBNodesViaXPath would be more convenient,
* but there are 3 JAXB bugs which detract from that (see Getting Started).

I also implemented but the same result

Code: Select all

   protected List<Object> getAllElementsFromObject(Object obj, Class<?> toSearch) {
        List<Object> result = new ArrayList<Object>();

           if (obj instanceof JAXBElement) {
               obj = ((JAXBElement<?>) obj).getValue();
           }
          
           if (obj instanceof SdtElement) {
              obj = ((SdtElement)obj).getSdtContent(); // implements ContentAccessor             
           }

           if (obj.getClass().equals(toSearch)) {
               result.add(obj);
           } else if (obj instanceof ContentAccessor) {
               List<?> children = ((ContentAccessor) obj).getContent();
               for (Object child : children) {
                   result.addAll(getAllElementsFromObject(child, toSearch));
               }
           }
      
      return result;
   }

You have the so-called "split run" problem, where Word is splitting your run of text with other markup in this case, you have a bookmark boundary in the middle of your text, plus CTMarkupRange).

https://github.com/plutext/docx4j/blob/ ... epare.java should help; you'll have to see whether it handles all the junk. If any junk remains, you can extend VariablePrepare to handle it.

The alternative is to manually correct your input.

Thank you jason,
How can I manually correct your input ?

Regards. How can I delete the bookmarks and boudaries manually?

Hello Json,

after executing https://github.com/plutext/docx4j/blob/ ... epare.java, it saves the file but the CTBookmark and CTMarkupRange and still remains. How can I extend the class ?

Thank you.

Probably easiest to just make a copy of the class, then add:

Syntax: [ Download ] [ Hide ]

Syntax: [ Download ] [ Show ]

Using java Syntax Highlighting

                filterSettings.setRemoveBookmarks(true);
