[FIXED] I need to extract id from th class text

Issue

I have the HTML code below:

<div class="col-12 col-sm-6 col-md-6 col-xl-4 product type-product post-31121 status-publish first instock product_cat-tyres has-post-thumbnail purchasable product-type-simple">
<div class="col-12 col-sm-6 col-md-6 col-xl-4 product type-product post-31301 status-publish instock product_cat-tyres has-post-thumbnail purchasable product-type-simple">
<div class="col-12 col-sm-6 col-md-6 col-xl-4 product type-product post-28416 status-publish last instock product_cat-tyres has-post-thumbnail purchasable product-type-simple">

I need to extract the Id of each product presented in the class description using beatiful soup (31121/ 31301/ 28416 are the ids) how can i do that ?

Solution

Iterate over your selection extract class attribute, iterate over its classes and pick class starts with post-:

[c.split('-')[-1] for e in soup.select('div.type-product') for c in e['class'] if c.startswith('post-')]

or

[c.split('-')[-1] for e in soup.select('div[class*="post-"]') for c in e['class'] if c.startswith('post-')]

Example

html = '''
<div class="col-12 col-sm-6 col-md-6 col-xl-4 product type-product post-31121 status-publish first instock product_cat-tyres has-post-thumbnail purchasable product-type-simple">
<div class="col-12 col-sm-6 col-md-6 col-xl-4 product type-product post-31301 status-publish instock product_cat-tyres has-post-thumbnail purchasable product-type-simple">
<div class="col-12 col-sm-6 col-md-6 col-xl-4 product type-product post-28416 status-publish last instock product_cat-tyres has-post-thumbnail purchasable product-type-simple">
'''

soup = BeautifulSoup(html)

[c.split('-')[-1] for e in soup.select('div.type-product') for c in e['class'] if c.startswith('post-')]

output

['31121', '31301', '28416']
