python - 正则表达式匹配“\xa0”的问题

Answer 1

Use strip() to remove leading and trailing spaces

from scrapy.selector import Selector

content = "<p>数量：100-200个&nbsp;&nbsp;&nbsp;&nbsp;</p>"
strings = Selector(text=content).xpath('//p/text()').re_first(u'数量：(.+)\s$').strip()
print(strings)
print(len(strings))
"""
100-200个
8
"""
