How to substitute text in docx.

Hi,
 
I would like to change documents docx in Groovy or JAVA language. I can replace image or graph, but i don't know how i have to do to substitute keyword ($$$textToSubstitute) by new text (String).
 
I manage actually no problem to browse each paragraph (xwpfDoc.getParagraphs(i)), however in the next step I cannot browse the Run (I cannot find a method such paragraph.getRuns ()). This is a problem to replace the keyword with the replacement text in the right place, because I cannot use the specific Run containing the keyword.
 
I cannot find method in Apache POI (XWPF) to browse Run one by one. despite the fact that this method exist in (HWPF : Apache POI for .doc file)
...
int numCharRuns = paragraph.numCharacterRuns();
for (int j = 0; j < numCharRuns; j++) {
CharacterRun charRun = paragraph.getCharacterRun(j);
text = charRun.text();
if (text.contains(key)) {
int start = text.indexOf(key);
charRun.replaceText(key, value, start);
}
}
...
How can i do to browse each  Run in a docx file, with the help of Apache POI APIs or other?
 
Thank you for everyhelps!

You can use docx4j.

The docx4j equivalent of paragraph.getRuns() is paragraph.getParagraphContent()

There is also a method XmlUtils.unmarshallFromTemplate(String wmlTemplateString,
java.util.HashMap mappings)

Hi,

I'm working with docx4j. I'm trying to change the main title of the document and I do this:

        WordprocessingMLPackage wordMLPackage;
        wordMLPackage = WordprocessingMLPackage.load(new java.io.File(inputfilepath));

        //MARSHAL
        String xml = XmlUtils.marshaltoString(wordMLPackage.getMainDocumentPart().getJaxbElement(), true, true);
       
         //CHANGE (Replace a string)
        xml = xml.replaceAll("<w:t>Title of document</w:t>", "<w:t>New Title</w:t>");


        //UNMARSHAL
      wordMLPackage.getMainDocumentPart().addObject(org.docx4j.XmlUtils.unmarshalString(xml));
       
        // Now save it
          if (save) {
                System.out.println("Saved.");
                SaveToZipFile saver = new SaveToZipFile(wordMLPackage);
                saver.save(outPutFileName);
               
            }

But... when I compile it, I get some exceptions like this:


org.docx4j.openpackaging.exceptions.Docx4JException: Failed to add parts from relationships
    at org.docx4j.openpackaging.io.SaveToZipFile.addPartsFromRelationships(SaveToZipFile.java:319)
    at org.docx4j.openpackaging.io.SaveToZipFile.save(SaveToZipFile.java:130)
    at org.docx4j.openpackaging.io.SaveToZipFile.save(SaveToZipFile.java:80)
    at org.docx4j.samples.ChangeTitle.main(ChangeTitle.java:90)

Could someone help me, please?
Thank you!

I read in plutext forums that this problem has a solution: download the last release of docx4j 2.3.0, and with that, my program works perfectly. But finally, when i didn't know it, I changed my program, and now I do a text replace traversing the document, using org.docx4j.wml.Text objects. There is an example of it in docx4j samples.

Thanks!
