<ul>元素内的<u>标记甚至可以强调子弹点

Question

我想将以下流转换为pdf。虽然我这样做，但即使我给了<u> tag inside <li> tag，也会强调子弹。我想在c＃应用程序中执行此操作。我为此使用了itextsharp dll。已经给出了下面的流。

<Form Title="iTextsharp <u> inside <ul> issue" Scrollable="True"><![CDATA[

<p>xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx </p>
<p><b><u>xxxxxx:</u></b>  Description </p>
    <ul>
        <li>xxxxxxxxxx common occurrences.</li>
        <li>yyyyyyyy.</li>
        <li>Aaaaaaaaaaaaaaia.</li>
        <li>bbbbbbbbbbbb.</li>
        <li>cccccccccccccccccc.</li>
        <li>ddddddddddddddddddddddddd.</li>     
</ul>

<ul>
    <li><b><u>xxxxxxxx </u>(xxxxxxxxxxxxxx):</b></li>
        <ul style="list-style-type:none">
            <li>asdfasdadasdaasdadasdasdasd.</li>
        </ul>
    <li><b><u>xmnxcvbzxnmn </u>(kjdbvdbvbdvbsdakvjsdkjvkjdsvjkdjvjkdfv):</b></li>

            <li>vabc</li>
            <li>abc</li>            
        </ul>
    <li><b><u>abc </u>abc:</b> abc.</li>
    <li><b><u>abc:</u></b> abc.</li>
</ul>

<p><b><u>abc:</u></b> abcabcabcabcabcabc:</p>
