我正在使用 Python 和 lxml,但遇到错误
我的代码
>>>import urllib
>>>from lxml import html
>>>response = urllib.urlopen('http://www.edmunds.com/dealerships/Texas/Grapevine/GrapevineFordLincoln_1/fullservice-505318162.html').read()
>>>dom = html.fromstring(response)
>>>dom.xpath("//div[@class='description item vcard']")[0].xpath(".//p[@class='service-review-paragraph loose-spacing']")[0].text_content()

UnicodeDecodeError: 'utf8' codec can't decode byte 0x93 in position 477: invalid start byte
问题是出现在我正在获取的 div 中的特殊字符。如何在不丢失任何数据的情况下对文本进行编码/解码?
最佳答案
解析器假设这是一个 utf-8 文件,但它不是。最简单的做法是首先通过了解页面的编码将其转换为 unicode
>>> url = urllib.urlopen('http://www.edmunds.com/dealerships/Texas/Grapevine/GrapevineFordLincoln_1/fullservice-505318162.html')
>>> url.headers.get('content-type')
'text/html; charset=ISO-8859-1'
>>> response = url.read()
#let's convert to unicode first
>>> response_unicode = codecs.decode(response, 'ISO-8859-1')
>>> dom = html.fromstring(response_unicode)
#and now...
>>> dom.xpath("//div[@class='description item vcard']")[0].xpath(".//p[@class='service-review-paragraph loose-spacing']")[0].text_content()
