在Python BeautifulSoup4中，如何提取这样的特殊文本

我正试图提取一些字符串。从本文中：

    text = "<li>(<a rel="nofollow" class="external text" href="http://www.icd9data.com/getICD9Code.ashx?
    icd9=999.1">999.1</a>) <a href="/wiki/Air_embolism" title="Air embolism">Air embolism</a> as
    a complication of medical care not elsewhere classified</li>"

任何人知道任何方法都可以调用我想要的字符串吗？ 谢谢

印刷品

(999.1) Air embolism as
a complication of medical care not elsewhere classified

get_text

方法返回标记中的所有文本，甚至是子标记的一部分

使用，你可以使用

import lxml.html as LH
text = """<li>(<a rel="nofollow" class="external text" href="http://www.icd9data.com/getICD9Code.ashx?
icd9=999.1">999.1</a>) <a href="/wiki/Air_embolism" title="Air embolism">Air embolism</a> as
a complication of medical care not elsewhere classified</li>"""

doc = LH.fromstring(text)
for tag in doc.xpath('//li/a[2]'):
    print(tag.tail)

(999.1) Air embolism as
a complication of medical care not elsewhere classified

import lxml.html as LH
text = """<li>(<a rel="nofollow" class="external text" href="http://www.icd9data.com/getICD9Code.ashx?
icd9=999.1">999.1</a>) <a href="/wiki/Air_embolism" title="Air embolism">Air embolism</a> as
a complication of medical care not elsewhere classified</li>"""

doc = LH.fromstring(text)
for tag in doc.xpath('//li/a[2]'):
    print(tag.tail)

 as
a complication of medical care not elsewhere classified
