Replacing a text in Apache POI XWPF

Question

I just found Apache POI library very useful for editing Word files using Java. Specifically, I want to edit a DOCX file using Apache POI\'s XWPF classes. I

Answer 1

As of the date of writing, none of the answers replace properly.

Gagravars answer does not include cases where words to replace are split in runs; Thierry Boduins solution sometimes left words to replace blank when they were after other words to replace, also it does not check tables.

Using Gagtavars answer as base I have also checked the run before current run if the text of both runs contain the word to replace, adding else block. My addition in kotlin:

if (text != null) {
        if (text.contains(findText)) {
            text = text.replace(findText, replaceText)
            r.setText(text, 0)
        } else if (i > 0 && p.runs[i - 1].getText(0).plus(text).contains(findText)) {
            val pos = p.runs[i - 1].getText(0).indexOf('$')
            text = textOfNotFullSecondRun(text, findText)
            r.setText(text, 0)
            val findTextLengthInFirstRun = findTextPartInFirstRun(p.runs[i - 1].getText(0), findText)
            val prevRunText = p.runs[i - 1].getText(0).replaceRange(pos, findTextLengthInFirstRun, replaceText)
            p.runs[i - 1].setText(prevRunText, 0)
        }
    }

private fun textOfNotFullSecondRun(text: String, findText: String): String {
    return if (!text.contains(findText)) {
        textOfNotFullSecondRun(text, findText.drop(1))
    } else {
        text.replace(findText, "")
    }
}

private fun findTextPartInFirstRun(text: String, findText: String): Int {
    return if (text.contains(findText)) {
        findText.length
    } else {
        findTextPartInFirstRun(text, findText.dropLast(1))
    }
}

it is the list of runs in a paragraph. Same with the search block in the table. With this solution I did not have any issues yet. All formatting is intact.

Edit: I made a java lib for replacing, check it out: https://github.com/deividasstr/docx-word-replacer
