我从旧的 Primeface RichEditor 切换到了syncfusion WordEditor，并且使用下面的类从 html 转换为 sdft

import java.io.ByteArrayInputStream;
import java.io.InputStream;
import java.nio.charset.StandardCharsets;
import com.syncfusion.docio.FormatType;
import com.syncfusion.docio.WordDocument;
import com.syncfusion.ej2.wordprocessor.WordProcessorHelper;

public class SFDTAdapter {
    
    public static String sfdtToRtf(String sfdt) throws Exception {
        return WordProcessorHelper.save(sfdt, com.syncfusion.ej2.wordprocessor.FormatType.Rtf).toString();
    }
    
    public static String rtfToSfdt(String rtf) throws Exception {
        byte[] bytes = rtf.getBytes(StandardCharsets.UTF_8);
        InputStream stream = new ByteArrayInputStream(bytes);
        WordDocument document = new WordDocument(stream, FormatType.Rtf);
        String sfdt =  WordProcessorHelper.load(document);
        document.close();
        stream.close();
        return sfdt;
    }
    
    
    public static String htmlToSfdt(String html) throws Exception {
        byte[] bytes = html.getBytes(StandardCharsets.UTF_8);
        InputStream stream = new ByteArrayInputStream(bytes);
        WordDocument document = new WordDocument(stream, FormatType.Html);
        String sfdt = WordProcessorHelper.load(document);
        document.close();
        stream.close();
        return sfdt;
    }
    
    public static String sfdtToHtml(String sfdt) throws Exception {
        return WordProcessorHelper.save(sfdt, com.syncfusion.ej2.wordprocessor.FormatType.Html).toString();
    }
}

但是，当我处理旧寄存器时，出现以下问题“元素类型 'br' 必须由匹配的结束标记终止”。根据我读到的内容，这是因为 DocIO 验证内容是否遵循 xhtml 1 格式。有没有办法告诉 DocIO 忽略错误，或者不验证该格式？
