I am trying to replace a simple 'Place Holder in MS Word 2007 using Docx4J . I created the placeholder by . I created the placeholder by Reference > Insert Citation > Add New Placeholder`

Below is my Docx4J code

            System.out.println("Operation Completed");
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }
    }



    private WordprocessingMLPackage getTemplate(String name) throws Docx4JException, FileNotFoundException {

            }

        }
        return result;
    }

        private void replacePlaceholder(WordprocessingMLPackage template, String name, String placeholder ) {
        List<Object> texts = getAllElementFromObject(template.getMainDocumentPart(), Text.class);

        for (Object text : texts) {
            Text textElement = (Text) text;
            if (textElement.getValue().equals(placeholder)) {
                textElement.setValue(name);
            }
        }
    }



    private void writeDocxToStream(WordprocessingMLPackage template, String target) throws IOException, Docx4JException {
        File f = new File(target);
        template.save(f);
    }

}

This generated the below in Netbeans console.

However in Yohan2.docx, nothing is changed, it is a pure copy of Yohan.docx. What have I done wrong here?

UPDATE

I tested the MERGEFIELD example from the GITHUB but it also didn't work. Below is the output printed in console

Answer 1

A placeholder inserted via Reference > Insert Citation > Add New Placeholder results in something like:

  <w:sdt>
    <w:sdtPr>
      <w:id w:val="-963732549"/>
      <w:citation/>
    </w:sdtPr>
    <w:sdtContent>
      <w:r>
        <w:fldChar w:fldCharType="begin"/>
      </w:r>
      <w:r>
        <w:rPr>
          <w:lang w:val="en-AU"/>
        </w:rPr>
        <w:instrText xml:space="preserve"> CITATION PL1 \l 3081 </w:instrText>
      </w:r>
      <w:r>
        <w:fldChar w:fldCharType="separate"/>
      </w:r>
      <w:r>
        <w:rPr>
          <w:noProof/>
          <w:lang w:val="en-AU"/>
        </w:rPr>
        <w:t>(PL1)</w:t>
      </w:r>
      <w:r>
        <w:fldChar w:fldCharType="end"/>
      </w:r>
    </w:sdtContent>
  </w:sdt>

ie a CITATION field wrapped in a content control.

docx4j has an API for replacing MERGEFIELD and DOCPROPERTY fields, but not CITATION fields.

Is there a particular reason you are trying to use a CITATION field?

If you can swap to MERGEFIELD or DOCPROPERTY field, I'd do that. Otherwise, you could examine docx4j's code for handling those, and adapt it to handling CITATION.

Answer 2

Place Holder in Insert > Quick Parts > Field

Select MergeField

Copy merge field name as appears in the document together with the arrow characters to your code. replacePlaceholder(template,"Plane","placeholdernamewitharrowcharacters");
