python - lxml.etree为什么会自动加上加上</i>？-PHP中文网问答

正在学习lxml，代码如下：

from lxml import etree
text = '''
<i class="cell maincell">
    <p class="title">
        <a target="_blank" href="https://itjuzi.com/company/60321">
            <span>洋鼹鼠</span>
        </a>
    </p>
    <p>
        <span class="tags t-small c-gray-aset">
            <a href="https://itjuzi.com/investevents?scope=145">电子商务</a>
        </span>
        <span class="loca c-gray-aset t-small">
            <a href="https://itjuzi.com/investevents?prov=天津">天津</a>
        </span>
    </p>
</i>
'''
html = etree.HTML(text)
print(etree.tostring(html,encoding='utf-8').decode('utf-8'))

输出如下：

<html><body><i class="cell maincell">
    </i><p class="title">
        <a target="_blank" href="https://itjuzi.com/company/60321">
            <span>洋鼹鼠</span>
        </a>
    </p>
    <p>
        <span class="tags t-small c-gray-aset">
            <a href="https://itjuzi.com/investevents?scope=145">电子商务</a>
        </span>
        <span class="loca c-gray-aset t-small">
            <a href="https://itjuzi.com/investevents?prov=天津">天津</a>
        </span>
    </p>

</body></html>

主要不理解为什么<i>标签那里会出错呢？请问怎么解决这个问题？谢谢~
