Question

我正在为word文档开发一个比较工具，只要文档中我有需要突出显示段落中的子字符串。当我尝试突出显示使用run时，它突出显示整个段落而不是子字符串。

请您指导我们，如何为子字符串实现此目的。

我遇到了同样的问题。在这里，我发布了一个示例方法，您可以在其中突出显示运行中包含的子字符串。

private int highlightSubsentence(String sentence, XWPFParagraph p, int i) {
    //get the current run Style - here I might need to save the current style
    XWPFRun currentRun = p.getRuns().get(i);
    String currentRunText = currentRun.text();
    int sentenceLength = sentence.length();
    int sentenceBeginIndex = currentRunText.indexOf(sentence);
    int addedRuns = 0;
    p.removeRun(i);
    //Create, if necessary, a run before the highlight part
    if (sentenceBeginIndex > 0) {
        XWPFRun before = p.insertNewRun(i);
        before.setText(currentRunText.substring(0, sentenceBeginIndex));
        //here I might need to re-introduce the style of the deleted run
        addedRuns++;
    }

    // highlight the interesting part
    XWPFRun sentenceRun = p.insertNewRun(i + addedRuns);
    sentenceRun.setText(currentRunText.substring(sentenceBeginIndex, sentenceBeginIndex + sentenceLength));
    currentStyle.copyStyle(sentenceRun);
    CTShd cTShd = sentenceRun.getCTR().addNewRPr().addNewShd();
    cTShd.setFill("00FFFF");

    //Create, if necessary, a run after the highlight part
    if (sentenceBeginIndex + sentenceLength != currentRunText.length()) {
        XWPFRun after = p.insertNewRun(i + addedRuns + 1);
        after.setText(currentRunText.substring(sentenceBeginIndex + sentenceLength));
        //here I might need to re-introduce the style of the deleted run
        addedRuns++;
    }
    return addedRuns;
}

您可能需要保存已删除的运行的格式样式，以便使用旧格式进行新运行。

此外，如果您需要突出显示的字符串分布在多个运行中，则需要突出显示所有字符串，但核心方法是我发布的方法。
