Python 如何分析这些差距？

请帮助从易趣页面获取价格

在下面的脚本中，我从两个特定页面获取价格

import pprint
import requests
import lxml.etree
import lxml.html
import lxml.cssselect
import re


def get_doc(url):
    try:
        req = requests.get(url)
    except Exception:
        print('Error open. __', Exception)
    else:
        html = req.text
        doc = lxml.html.document_fromstring(html)
        return doc


for url in ['http://www.ebay.com/itm/DW-PDP-Concept-Pearlescent-White-Maple-Drumset-/121271668104?pt=US_Drums&hash=item1c3c5acd88', 'http://www.ebay.com/itm/LOT-OF-20-DRUM-SET-TUNING-KEYS-DW-TAMA-PEARL-SABIAN-and-OTHER-UNIQUE-KEYS-/291092068092?pt=US_Drums&hash=item43c67076fc']:
    doc = get_doc(url)
    title = doc.xpath('//h1[@id="itemTitle"]/text()')
    priceUSD = doc.xpath('//span[@itemprop="price"]/text()')
    print(title, priceUSD)

问题是第一页的价格有一个空格（&_n_b_s_p_；）。因此获取错误的xpath值文本（）。情况如下：

['DW/PDP概念珠光白色枫木圆桶]['US$1\xa0200,00'] [20个鼓组调音键！DW！塔玛！珀尔！萨比安！和其他 唯一的钥匙！！']['US$6,05']

p、 美国。

它的价格不正确：“US$1\xa0200,00”

替换

\xa0

：

priceUSD = [t.replace('\xa0', '') for t in
            doc.xpath('//span[@itemprop="price"]/text()')]

顺便说一句，我没有修改就得到了以下输出：

['DW/PDP Concept Pearlescent White Maple Drumset'] ['US $1,200.00']
['LOT OF 20 DRUM SET TUNING KEYS! DW! TAMA! PEARL! SABIAN! and OTHER UNIQUE KEYS!!'] ['US $6.05']

“//h1[@id=“itemtTitle”]/text（）”=>“//span[@itemprop=“price”]/text（）”@Sergey，你说得对。我从本地副本复制了错误的行。谢谢
