我已經(jīng)為此苦苦掙扎了幾天，我想知道也許有人可以幫助我。我想要完成的是處理一個包含一組問題和答案的文本文件。文件的內(nèi)容（.doc 或 .docx）如下所示：Document Name1. Question one:a. Answer one to question oneb. Answer two to question onec. Answer three to question one2. Question two:a. Answer one to question twoc. Answer two to question twoe. Answer three to question two到目前為止我嘗試過的是：通過 Apache POI 讀取文檔內(nèi)容，如下所示：fis = new FileInputStream(new File(FilePath));XWPFDocument doc = new XWPFDocument(fis);XWPFWordExtractor extract = new XWPFWordExtractor(doc);String extractorText = extract.getText();所以，到目前為止，我已經(jīng)掌握了文檔的內(nèi)容。接下來，我嘗試創(chuàng)建一個正則表達(dá)式模式，該模式將匹配問題開頭的數(shù)字和點(diǎn)（1. , 12.）并繼續(xù)直到它與冒號匹配：Pattern regexPattern = Pattern.compile("^(\\d|\\d\\d)+\\.[^:]+:\\s*$", Pattern.MULTILINE);Matcher regexMatcher = regexPattern.matcher(extractorText);但是，當(dāng)我嘗試遍歷結(jié)果集時，我找不到任何問題文本：while (regexMatcher.find()) {    System.out.println("Found");    for (int i = 0; i < regexMatcher.groupCount() - 2; i += 2) {        map.put(regexMatcher.group(i + 1), regexMatcher.group(i + 2));        System.out.println("#" + regexMatcher.group(i + 1) + " >> " + regexMatcher.group(i + 2));    }}由于我是 Java 新手，我不確定我哪里出錯了，希望有人能幫助我。此外，如果有人有更好的方法來創(chuàng)建帶有問題和相關(guān)答案的地圖，我們將不勝感激。先感謝您。編輯：我正在嘗試獲取類似 Map 的內(nèi)容，其中將包含鍵（問題文本）和另一個字符串列表，這些字符串將表示與該問題相關(guān)的一組答案，例如：Map<String, List<String>> desiredResult = new HashMap<>();    desiredResult.entrySet().forEach((entry) -> {        String       questionText = entry.getKey();        List<String> answersList  = entry.getValue();        System.out.println("Now at question: " + questionText);        answersList.forEach((answerText) -> {            System.out.println("Now at answer: " + answerText);        });    });這將生成以下輸出：Now at question: 1. Question one:Now at answer: a. Answer one to question oneNow at answer: b. Answer two to question oneNow at answer: c. Answer three to question one
