直接上代码：

import HTMLParser
class MyHTMLParser(HTMLParser.HTMLParser):
def __init__(self):
HTMLParser.HTMLParser.__init__(self)
self.links = []
def handle_starttag(self, tag, attrs):
#print "Encountered the beginning of a %s tag" % tag
if tag == "li":
if len(attrs) == 0:
pass
else:
for (variable, value) in attrs:
if variable == "data-cityid":
self.links.append(value)

if __name__ == "__main__":
html_code = """ <ul class="open-context"><li data-cityid="76" data-cityname="广州" class="open-context-item">广州</li><li data-cityid="77" data-cityname="深圳" class="open-context-item active">深圳</li><li data-cityid="52" data-cityname="北京" class="open-context-item">北京</li><li data-cityid="321" data-cityname="上海" class="open-context-item">上海</li><li data-cityid="180" data-cityname="武汉" class="open-context-item">武汉</li><li data-cityid="192" data-cityname="咸宁" class="open-context-item">咸宁</li><li data-cityid="220" data-cityname="南京" class="open-context-item">南京</li><li data-cityid="221" data-cityname="苏州" class="open-context-item">苏州</li><li data-cityid="222" data-cityname="无锡" class="open-context-item">无锡</li><li data-cityid="235" data-cityname="赣州" class="open-context-item">赣州</li><li data-cityid="244" data-cityname="沈阳" class="open-context-item">沈阳</li><li data-cityid="245" data-cityname="大连" class="open-context-item">大连</li><li data-cityid="284" data-cityname="青岛" class="open-context-item">青岛</li><li data-cityid="322" data-cityname="成都" class="open-context-item">成都</li><li data-cityid="343" data-cityname="天津" class="open-context-item">天津</li><li data-cityid="144" data-cityname="廊坊" class="open-context-item">廊坊</li><li data-cityid="111" data-cityname="贵阳" class="open-context-item">贵阳</li><li data-cityid="53" data-cityname="福州" class="open-context-item">福州</li><li data-cityid="60" data-cityname="厦门" class="open-context-item">厦门</li><li data-cityid="78" data-cityname="潮州" class="open-context-item">潮州</li><li data-cityid="79" data-cityname="东莞" class="open-context-item">东莞</li><li data-cityid="80" data-cityname="佛山" class="open-context-item">佛山</li><li data-cityid="82" data-cityname="惠州" class="open-context-item">惠州</li><li data-cityid="83" data-cityname="江门" class="open-context-item">江门</li><li data-cityid="86" data-cityname="梅州" class="open-context-item">梅州</li><li data-cityid="92" data-cityname="云浮" class="open-context-item">云浮</li><li data-cityid="95" data-cityname="中山" class="open-context-item">中山</li><li data-cityid="96" data-cityname="珠海" class="open-context-item">珠海</li><li data-cityid="97" data-cityname="南宁" class="open-context-item">南宁</li><li data-cityid="383" data-cityname="杭州" class="open-context-item">杭州</li></ul>"""
hp = MyHTMLParser()
hp.feed(html_code)
hp.close()
print(hp.links)

注：2.7和3.0以上import方法不一样，上述为2,7引用；3.0以上用from html.parser import HTMLParser

def handle_starttag(self, tag, attrs)根据实际需求修改此函数
