我试图得到delititle，然后在delititle下得到两个菜单项Made to Order Deli Core和{}？我用美丽的汤4来做这个，但它不起作用。主菜时代也是如此吗？在

    </table>

或者，如果我能把它转换成这样的XML格式：

^{pr2}$

提前非常感谢你，我真的很感谢你抽出时间来帮助我。在

实际上，我使用了beautiful soup和element tree（用于xml解析） 获取<span>中的所有元素

        <tr class="lun">
            <td class="station">&nbsp;Deli</td>

            <td class="menuitem">

你可以这样做：

# -*- coding: utf-8 -*-

soup = BeautifulSoup(html)
title = soup.find('td', class_='station').text.strip()

spans = soup.find_all('span', class_='ul')

# create the root of the XML file
root = ET.Element("counter")
root.set("name", title)

for item in spans:
    # retrieve the text inside the <td class="station">
    text = list(list(item.parents)[2].previous_siblings)[1].text.strip()
    if text == u'Entrée':
        break

    dish = ET.SubElement(root, 'dish')
    name = ET.SubElement(dish, 'name')
    name.text = item.text.rstrip()

tree = ET.ElementTree(root)
tree.write("filename.xml")

这是所需xml文件的内容：

^{pr2}$

非常重要的是在文件的开头包含下面的# -*- coding: utf-8 -*-行，以避免重音问题，有关详细信息，请参见SyntaxError: Non-ASCII character '\xa3' in file when function returns '£'。在
