Plutext

Hi,

I have this scenario: I use a template document for the first 7 pages of my document, because they are generally always the same. After that, I add about 400 pages of produced formatted output to the document. This all works very nice with docX4J - thanks for that.

Now I need to add something to the template document. The 3rd page is reserved for statistical data, so I somehow need to get to that point programmatically and insert a table there that I generate at runtime.

How can I navigate to that part of the page using docx4J and insert there?

kind regards,
Artur

Hi Artur,

If you know the text of the paragraph preceding the place where you want to put the table, the following code will do it:

Code: Select all

    void insertTable(WordprocessingMLPackage pkg, String afterText, Tbl table)
    throws Exception {
        Body b = pkg.getMainDocumentPart().getJaxbElement().getBody();
        int addPoint = -1, count = 0;
        for (Object o : b.getEGBlockLevelElts()) {
            if (o instanceof P && getElementText(o).startsWith(afterText)) {
                addPoint = count + 1;
                break;
            }
            count++;
        }
        if (addPoint != -1)
            b.getEGBlockLevelElts().add(addPoint, table);
        else {
            // didn't find paragraph to insert after...
        }
    }

   String getElementText(Object jaxbElem) throws Exception {
        StringWriter sw = new StringWriter();
        TextUtils.extractText(jaxbElem, sw);
        return sw.toString();
    }


Basically, a table can be a peer/sibling of paragraph as a child of body. Note the little utility method getElementText() to extract the text from a paragraph without formatting. My calling code looks like this:

Code: Select all

        WordprocessingMLPackage pkg = WordprocessingMLPackage.load(new File("/tmp/template.docx"));
        Tbl table = TblFactory.createTable(3, 3, 100);
        insertTable(pkg, "Now here is a table", table);
        pkg.save(new File("/tmp/filled-template.docx"));


Hope that helps,

dave

Thanks for your answer. I fixed it in a similar way. Since the start of my document is a template file I created, the insertion must be at the same position every time. I just hoped there might be a less hardcoded way for me to find that place. But I think looking for a String or something specific there is probably the only way to find that.

I thought maybe there is a method that inserts at a specific position, like "insertTableAtPage( int pagenumber)" or something similar to that, so I could put that thing always on page 3 for example.

Cheers!
