replace text with paragraph

[fachhoch]

I want to modify my word by replacing place holders with actual text , in my case I created a placeholder and would like to replace this with a paragraph , I tried the example of replacing text , but can I replace a simple text with whole paragraph ?

Code: Select all

         @Override
         public List<Object> apply(Object object) {
            if (object instanceof org.docx4j.wml.Text){
               Text  wText=(org.docx4j.wml.Text) object;
               if(wText.getValue().equals("formattedAuditNumber")){
                  wText.setValue("A-123-456-9876");
               }
            }
            return null;
         }




I tried playing with OpenMainDocumentAndTraverse.java, this is what I tried and it worked , now I want to create a new paragraph and replace it if text is formattedAuditNumber , please advice me how to.
Thanks a lot.

Do you want to replace a single word by a paragraph, is this ?

[fachhoch]

Yes. Its a place holder for a paragraph.
Please advice me hot to.

I'm just taking some parts from

_____________________________________________
Selecting your insertion/editing point;
accessing JAXB nodes via XPath

Sometimes, XPath is a succinct way to select the things you need to change.

Happily, from docx4j 2.5.0, you can do use XPath to select JAXB nodes:

MainDocumentPart documentPart = wordMLPackage.getMainDocumentPart();

String xpath = "//w:p";

List<Object> list = documentPart.getJAXBNodesViaXPath(xpath, false);

These JAXB nodes are live, in the sense that if you change them, your document changes.

There is a limitation however: the xpath expressions are evaluated against the XML document as it was when first opened in docx4j. You can update the associated XML document once only, by passing true into getJAXBNodesViaXPath. Updating it again (with current JAXB 2.1.x or 2.2.x) will cause an error.
_____________________________________________

I think that this is enough...

[fachhoch]

I tried this

Code: Select all


                    WordprocessingMLPackage wordMLPackage =
         WordprocessingMLPackage .load(new java.io.File("e://dev//java2word//word2java//ADL.docx"));
      MainDocumentPart documentPart = wordMLPackage.getMainDocumentPart();

               String xpath = "//w:r[w:t[contains(text(),'auditFindings')]]";
      List<Object> list = documentPart.getJAXBNodesViaXPath(xpath, true);
      list.clear();
      list.add(getFindingText());
      list.add(getAuditFinding());
      
       wordMLPackage.save(new File("e://dev//java2word//word2java//ADL-new-2.docx"));



but nothing was updated in the document can you please tell me whats wrong with my code ?

I debug this and documentPart.getJAXBNodesViaXPath(xpath, true); returns a list , I am just calling clear list and adding more to the list , why is it not changing the document?

[lucasfgc]

Just try it...
Remember, i'm using "getJAXBNodesViaXPath"

Code: Select all

WordprocessingMLPackage wordMLPackage =
WordprocessingMLPackage .load(new java.io.File("e://dev//java2word//word2java//ADL.docx"));
MainDocumentPart documentPart = wordMLPackage.getMainDocumentPart();

String xpath = "//w:r[w:t[contains(text(),'auditFindings')]]";
List<Object> list = documentPart.getJAXBNodesViaXPath(xpath, true);

for (Object obj : list) {

list = (Text) ((JAXBElement) obj).getValue();
String textValue = this.list.getValue();

//now you have a String - textValue... just modify it
textValue = "your own string";

list.setValue(this.textValue);

}

wordMLPackage.save(new File("e://dev//java2word//word2java//ADL-new-2.docx"));

I hope that it helps...
Cheers.

Thanks a lot for your quick reply ,

[fachhoch]

here is my whole code

Code: Select all

   public static void testDoc() throws Exception{
      System.out.println("test");
      WordprocessingMLPackage wordMLPackage =
         WordprocessingMLPackage .load(new java.io.File("e://dev//java2word//word2java//ADL.docx"));
      MainDocumentPart documentPart = wordMLPackage.getMainDocumentPart();
      org.docx4j.wml.Document wmlDocumentEl = (org.docx4j.wml.Document) documentPart.getJaxbElement();
      Body body = wmlDocumentEl.getBody();
      Callback  callback= new Callback() {
         String indent = "";
         @Override
         public void walkJAXBElements(Object parent) {
            indent += "    ";

            List children = getChildren(parent);
            if (children != null) {

               for (Object o : children) {

                  // if its wrapped in javax.xml.bind.JAXBElement, get its
                  // value
                  o = XmlUtils.unwrap(o);

                  this.apply(o);

                  if (this.shouldTraverse(o)) {
                     walkJAXBElements(o);
                  }
               }
            }
            indent = indent.substring(0, indent.length() - 4);
         }
         
         @Override
         public boolean shouldTraverse(Object object) {
            return true;
         }
         
         @Override
         public List<Object> getChildren(Object object) {
            return TraversalUtil.getChildrenImpl(object);
         }
         
         @Override
         public List<Object> apply(Object object) {
            if (object instanceof org.docx4j.wml.Text){
               Text  wText=(org.docx4j.wml.Text) object;
               if(wText.getValue().equals("formattedAuditNumber")){
                  wText.setValue("A-123-456-9876"); //  here this works , I can change text
               }
            }
            return null;
         }
      };
      new TraversalUtil(body, callback);
      
      String xpath = "//w:r[w:t[contains(text(),'auditFindings')]]";
      
      List<Object> list = documentPart.getJAXBNodesViaXPath(xpath, true);

      list.add(getAuditFinding());
      
       wordMLPackage.save(new File("e://dev//java2word//word2java//ADL-new-2.docx"));
      
   }
I was able to change text but donot know how to replace a text with   list of Paragraps,
the methods getFindingText(),  getAuditFinding()  creates two new paragraph , I can add these two paragraph at the end  fo the doumenht but how can I  add in the middle somewhere ?


Code: Select all


   private static P getFindingText(){
      org.docx4j.wml.ObjectFactory factory = new org.docx4j.wml.ObjectFactory();
      org.docx4j.wml.P  p = factory.createP();
      org.docx4j.wml.Text  t = factory.createText();
      t.setValue("A manual reconciliation process has been instituted.  The current reconciliation process is at the fund center level. There are written procedures for preparing the PSC 272. .  The Financial Accountants reconcile the expends vs. allots spreadsheets to balances in FETS on a monthly basis. The DCS Controller or FSSA Director of Federal funding reveiw and certify the reports.");
      org.docx4j.wml.R  run = factory.createR();
      run.getContent().add(t);
      p.getContent().add(run);
      return p;
   }
   
   
   private static P  getAuditFinding(){
      org.docx4j.wml.ObjectFactory factory = new org.docx4j.wml.ObjectFactory();
      
      org.docx4j.wml.P  p = factory.createP();
      
      org.docx4j.wml.Text  t = factory.createText();
      t.setValue("Audit Finding");
      
      org.docx4j.wml.R  run = factory.createR();
      run.getContent().add(t);
      
      p.getContent().add(run);
      
      org.docx4j.wml.RPr rpr = factory.createRPr();      
      org.docx4j.wml.BooleanDefaultTrue b = new org.docx4j.wml.BooleanDefaultTrue();
       b.setVal(true);      
       rpr.setB(b);
      
       rpr.setU(new U(){
          {
             setVal(UnderlineEnumeration.THICK);
          }
       });
      
       run.setRPr(rpr);

At Getting Started Guide, you can find the session

"Adding a paragraph of text"

You ought to read it and i think that you'll be able to do whatever you want!
It's clearly enough...

[fachhoch]

I was able to adda new paragraph , but not at the place I want to add ,when I call

Code: Select all

documentPart.addObject(o)


it always add at the bottom , but I want to add in the middle of the document , all I am asking is how to add a paragraph in the middle of the document ?

[lucasfgc]

Ok, here we go...

Try it!

Code: Select all

    public static void testDoc() throws Exception {
        System.out.println("test");
        WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.load(new java.io.File("teste.docx"));
        MainDocumentPart documentPart = wordMLPackage.getMainDocumentPart();
        org.docx4j.wml.Document wmlDocumentEl = (org.docx4j.wml.Document) documentPart.getJaxbElement();

        String xpath = "//w:r[w:t[contains(text(),'auditFindings')]]";

        System.out.println("XPATH " + xpath);
        List<Object> list = documentPart.getJAXBNodesViaXPath(xpath, true);


        for (Object obj : list) {
            org.docx4j.wml.ObjectFactory factory = new org.docx4j.wml.ObjectFactory();
            org.docx4j.wml.Text t = factory.createText();
            t.setValue("A manual reconciliation process has been instituted.  The current reconciliation process is at the fund center level. There are written procedures for preparing the PSC 272. .  The Financial Accountants reconcile the expends vs. allots spreadsheets to balances in FETS on a monthly basis. The DCS Controller or FSSA Director of Federal funding reveiw and certify the reports.");
            ((R) obj).getContent().add(t);
        }

        wordMLPackage.save(new File("test.docx"));

    }

edit:
is better if you clear your content before add
i'll not do it into the code...

[fachhoch]

Thanks a lot your code worked , I am able to add content in place holders , here a new issue,
I will generating the document and pdf at the same time , I update the document saving this I see all the new content , but If I pass this to PdfConversion its not showing the new added paragraph.

Code: Select all

      WordprocessingMLPackage wordMLPackage =
         WordprocessingMLPackage .load(new java.io.File("e://dev//java2word//word2java//ADL.docx"));
      MainDocumentPart documentPart = wordMLPackage.getMainDocumentPart();

      String xpath = "//w:r[w:t[contains(text(),'auditFindings')]]";
      
      List<Object> list = documentPart.getJAXBNodesViaXPath(xpath, true);
      for(Object obj : list){
         List<Object>  objContent=((R)obj).getContent();
         objContent.clear();   
         objContent.add(getAuditFinding());
         objContent.add(getFindingText());
      }
       wordMLPackage.save(new File("e://dev//java2word//word2java//ADL-new-2.docx"));
      
      org.docx4j.convert.out.pdf.PdfConversion c= new org.docx4j.convert.out.pdf.viaXSLFO.Conversion(wordMLPackage);
       OutputStream os = new java.io.FileOutputStream("e://dev//java2word//word2java//ADL-new-2.pdf");
      c.output(os, new PdfSettings() );



[lucasfgc]

after saving your new document, try to load your package again and check if it works...

[fachhoch]

I just posted a new topic with this issue , I tried loading the document and call pdf conversion it did not work , alos I opened in openoffice it did not work.
