Question

我怎样才能做一个＆＃39;或＆＃39;在正则表达式。我读到我需要简单地将各种表达式放入括号中，但是当我尝试在＆Total;＆＃39; Total：＆＃39;之后获得任何输出时，以下findall不起作用。或者＆＃39;价格为1晚@＆＃39;。

p = re.findall(r'(Total: (.*))(Price for 1 night: (.*))',s)

提供更多背景信息：

prices1=[]

soup = bs(content, 'lxml')
s=soup.prettify()
p = re.findall(r'(Total: (.*))|(Price for 1 night: (.*))',s)
for x in p:
    if '£' in x:
        num=int(x.replace('£',''))
        prices1.append(num)

示例值：

<strong class="price scarcity_color sr_gs_rackrate_price
 anim_rack_rate  
" title="Price for 1 night £69">
<b>
<span class="sr_gs_rackrate_total">Total: </span>
£69
</b>
</strong>
<td class="totalPrice" colspan="3">
<div data-component="track" data-hash="OLNYSRfCbdWGffSRe" data-stage="1" data-track="view"></div>
Total: £145
</td>

Answer 1

首先，您应该清理输入，删除每个带有替换的HTML标记以及此正则表达式</?[^>]*>。

然后你会有Total: £69 Total: £145之类的东西。由于您不希望与实际价格匹配£69 Total: £145，因此您必须将.更改为[^\s]（除了空白之外的任何内容）。

然后您只需在条件之间添加|：

Total: ([^\s]*)|Price for 1 night: ([^\s]*)
