java - 使用 Apache POI (Java) 将 .docx 中的文本替换为表格

Question

因此，我尝试使用 Apache POI(版本 3.15)在 .docx 文件中的某个点插入表格。我可以使用下面的代码创建它。这会将我需要的表格放入文档的末尾。 (如果这是多余的，我很抱歉!尝试提供尽可能多的信息!)

    /* Creates table for the questions */
private XWPFTable createMainTable(XWPFDocument doc, ArrayList<String> qs, ArrayList<String> avgScores, ArrayList<String> favScores){ 
    XWPFTable table = doc.createTable();

    int currRow = 0;
    for(String q : qs){
        XWPFTableRow curRow = table.getRow(currRow);
        if(currRow == 0){
            curRow.getCell(0).setText("Question");
        }else{
        curRow.getCell(0).setText(q);
        }
        if(currRow < qs.size()-1){
            table.createRow();
            currRow++;
        }else{
            currRow++;
        }
    }
    currRow = 0;
    for(String avg : avgScores){
        XWPFTableRow curRow = table.getRow(currRow);
        curRow.addNewTableCell();
        if(currRow == 0){
            curRow.getCell(1).setText(" Average Score ");
        }else{
            curRow.getCell(1).setText(avg);
        }
        currRow++;    
    }
    currRow = 0;
    for(String fav : favScores){
        XWPFTableRow curRow = table.getRow(currRow);
        curRow.addNewTableCell();
        if(currRow == 0){
            curRow.getCell(2).setText(" Favorable Score ");
        }else{
            curRow.getCell(2).setText(fav);
        }
        currRow++;
    }
    return table;
}

现在，为了替换文档中的其余文本，我使用以下方法:

    /* Replace text in the document */
private long replaceText(ArrayList<String> comments, String targ, XWPFDocument doc) {
long count = 0;
for (XWPFParagraph paragraph : doc.getParagraphs()) {
  List<XWPFRun> runs = paragraph.getRuns();

    StringBuilder sb = new StringBuilder();
    for (String c : comments){
        sb.append(c);
        sb.append("|");
    }
    String find = targ;
    String repl = sb.toString();
    TextSegement found = paragraph.searchText(find, new PositionInParagraph());
    if ( found != null ) {
      count++;
      if ( found.getBeginRun() == found.getEndRun() ) {
        // whole search string is in one Run
        XWPFRun run = runs.get(found.getBeginRun());
        String runText = run.getText(run.getTextPosition());
        String replaced = runText.replace(find, repl);
        run.setText(replaced, 0);
      } else {
        // The search string spans over more than one Run
        // Put the Strings together
        StringBuilder b = new StringBuilder();
        for (int runPos = found.getBeginRun(); runPos <= found.getEndRun(); runPos++) {
          XWPFRun run = runs.get(runPos);
          b.append(run.getText(run.getTextPosition()));
        }                       
        String connectedRuns = b.toString();
        String replaced = connectedRuns.replace(find, repl);

        // The first Run receives the replaced String of all connected Runs
        XWPFRun partOne = runs.get(found.getBeginRun());
        partOne.setText(replaced, 0);
        // Removing the text in the other Runs.
        for (int runPos = found.getBeginRun()+1; runPos <= found.getEndRun(); runPos++) {
          XWPFRun partNext = runs.get(runPos);
          partNext.setText("", 0);
        }                          
      }
    }     
}
return count;}  

第二个方法的作用是在文档中查找某个关键字，并将其替换为字符串。现在，它传递了一个 ArrayList，但是当我尝试不同的东西时，情况会发生变化。我能够获取要打印的表的内存地址(通过将输入更改为 XWPFTable)，但这只是我所能得到的。我觉得我错过了一些愚蠢的东西，但我就是无法弄清楚。

非常感谢Axel ，我能够得到想要的结果!我稍微改变了我的创建方法，只是传递了一个空表来填充。然后，像 Axel 建议的那样使用光标，它现在找到目标字符串(“%TABLE”)，并将其替换为表格，完全按照我的需要。

    /* Replaces table */
private long replaceTable(XWPFDocument doc, ArrayList<String> qs, ArrayList<String> avgScores, ArrayList<String> favScores) {
    XWPFTable table = null;
    long count = 0;
     for (XWPFParagraph paragraph : doc.getParagraphs()) {
       List<XWPFRun> runs = paragraph.getRuns();
         String find = "%TABLE";
         TextSegement found = paragraph.searchText(find, new PositionInParagraph());
         if ( found != null ) {
           count++;
           if ( found.getBeginRun() == found.getEndRun() ) {
             // whole search string is in one Run
             XmlCursor cursor = paragraph.getCTP().newCursor();
             table = doc.insertNewTbl(cursor);
             XWPFRun run = runs.get(found.getBeginRun());
             // Clear the "%TABLE" from doc
            String runText = run.getText(run.getTextPosition());
            String replaced = runText.replace(find, "");
            run.setText(replaced, 0);
           } else {
             // The search string spans over more than one Run
             StringBuilder b = new StringBuilder();
             for (int runPos = found.getBeginRun(); runPos <= found.getEndRun(); runPos++) {
               XWPFRun run = runs.get(runPos);
               b.append(run.getText(run.getTextPosition()));
             }                       
             String connectedRuns = b.toString();
             XmlCursor cursor = paragraph.getCTP().newCursor();
             table = doc.insertNewTbl(cursor);
             String replaced = connectedRuns.replace(find, ""); // Clear search text

             // The first Run receives the replaced String of all connected Runs
             XWPFRun partOne = runs.get(found.getBeginRun());
             partOne.setText(replaced, 0);
             // Removing the text in the other Runs.
             for (int runPos = found.getBeginRun()+1; runPos <= found.getEndRun(); runPos++) {
               XWPFRun partNext = runs.get(runPos);
               partNext.setText("", 0);
             }
           }
         }     
     }
     fillTable(table, qs, avgScores, favScores);
     return count;
}
