无法将所有元素从html带到与java具有相同标记的docx

Question

我有一个项目从html转换为带有java的docx，在html文档中我有2个段落，带有2个标题作为标题，但是当它们转换为docx格式时，只有一个段落成功转换，但另一个段落即使具有相同的标记也不会转换。看下面的图片

代码看起来像这样

import java.io.File;
import java.io.FileOutputStream;
import java.util.List;
import java.util.Set;
import static org.apache.poi.hslf.model.textproperties.TextPropCollection.TextPropType.paragraph;
import org.apache.poi.openxml4j.opc.OPCPackage;
import org.apache.poi.xwpf.usermodel.VerticalAlign;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFRun;
import org.zwobble.mammoth.DocumentConverter;
import org.zwobble.mammoth.Result;

/**

public class TestWord {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        // TODO code application logic here
        try
        {
            File file = new File("src/test/TEST.docx");
            DocumentConverter converter = new DocumentConverter();
            Result<String> result = converter.extractRawText(file);
            String html = result.getValue(); // The generated HTML
            Set<String> warnings = result.getWarnings(); // Any warnings during conversion

            String[] part = html.split("<p>");
            String[] part2 = html.split("<h1>");

            FileOutputStream out = new FileOutputStream(new File("testformat.docx"));
            XWPFDocument doc = new XWPFDocument();
            XWPFParagraph paragraph = doc.createParagraph();

            XWPFRun paragraphOneRunOne = paragraph.createRun();            

            XWPFRun paragraphOneRunThree = paragraph.createRun();            

            for (int i = 0; i < html.length(); i++) 
            {
            if (i % 2 != 0) 
            {          
                paragraphOneRunOne.setBold(true);
                paragraphOneRunOne.setItalic(true);
                paragraphOneRunOne.setText(part[i].trim());
                paragraphOneRunOne.addBreak();

                paragraphOneRunThree.setStrike(true);
                paragraphOneRunThree.setFontSize(20);
                paragraphOneRunThree.setSubscript(VerticalAlign.SUBSCRIPT);
                paragraphOneRunThree.setText(part2[i].trim());

                System.out.println(part2[i].trim());
                System.out.println(part[i].trim());

                    doc.write(out);
                    out.close();
            }


            System.out.println("testformat.docx written successully");
            }
            System.out.println("Success");
        } catch(Exception e) {
            e.printStackTrace();
        }  
    }

}

问题是，当它具有相同的标签时，如何将html中的所有段落转换为docx格式？谢谢你的关注。抱歉我的英文不好
