删除 scrapy xpath 中的特殊字符

Question

Cannot seem to accomplish after many hours. I am trying to edit a script.

Price from scrapy = $123,456 I need 123456 instead.

I have tried this but get attribute errors and more.

price_txt = response.xpath(".//dt[contains(text(), 'List Price')]/following-sibling::dd/text()").extract_first()


price = price_txt.translate(str.maketrans('', '', '.,$()'))

Answer 1

Use.replace()

price_txt = response.xpath(".//dt[contains(text(), 'List Price')]/following-sibling::dd/text()").extract_first()


price = price_txt.replace('$', '').replace(',', '')

Answer 2

Using Regex.

Ex:

import re

price_txt = "$123,456"
print(re.sub(r"[^\d]", "", price_txt))

---

Or str.isdigit

Ex:

print("".join(i for i in price_txt if i.isdigit()))

Output:

123456
123456
