我試圖在with下的標簽中獲取image-file屬性（相對鏈接）中的鏈接（我不想要鏈接）。imgdivid previewImagessrc這是示例 HTML：<div id="previewImages"> <div class="thumb"> <a><img src="https://example.com/s/15.jpg" image-file="/image/15.jpg" /></a> </div> <div class="thumb"> <a><img src="https://example.com/s/2.jpg" image-file="/image/2.jpg" /> </a> </div> <div class="thumb"> <a><img src="https://example.com/s/0.jpg" image-file="/image/0.jpg" /> </a> </div> <div class="thumb"> <a><img src="https://example.com/s/3.jpg" image-file="/image/3.jpg" /> </a> </div> <div class="thumb"> <a><img src="https://example.com/s/4.jpg" image-file="/image/4.jpg" /> </a> </div></div>我嘗試了以下操作，但它只給了我第一個鏈接，而不是全部：import sysimport urllib2from bs4 import BeautifulSoupquote_page = sys.argv[1] # this should be the first argument on the command linepage = urllib2.urlopen(quote_page)soup = BeautifulSoup(page, 'html.parser')images_box = soup.find('div', attrs={'id': 'previewImages'})if images_box.find('img'): imagesurl = images_box.find('img').get('image-file')print imagesurl如何獲取image-fileattritube 中所有img標簽的鏈接divwith class previewImages？

利用 .findAll
前任：
from bs4 import BeautifulSoup
html = """<div id="previewImages">
<div class="thumb"> <a><img src="https://example.com/s/15.jpg" image-file="/image/15.jpg" /></a> </div>
<div class="thumb"> <a><img src="https://example.com/s/2.jpg" image-file="/image/2.jpg" /> </a> </div>
<div class="thumb"> <a><img src="https://example.com/s/0.jpg" image-file="/image/0.jpg" /> </a> </div>
<div class="thumb"> <a><img src="https://example.com/s/3.jpg" image-file="/image/3.jpg" /> </a> </div>
<div class="thumb"> <a><img src="https://example.com/s/4.jpg" image-file="/image/4.jpg" /> </a> </div>
</div>"""
soup = BeautifulSoup(html, "html.parser")
images_box = soup.find('div', attrs={'id': 'previewImages'})
for link in images_box.findAll("img"):
print link.get('image-file')
輸出：
/image/15.jpg
/image/2.jpg
/image/0.jpg
/image/3.jpg
/image/4.jpg

我認為將 id 與傳遞給的屬性選擇器一起使用會更快 select
from bs4 import BeautifulSoup as bs
html = '''
<div id="previewImages">
<div class="thumb"> <a><img src="https://example.com/s/15.jpg" image-file="/image/15.jpg" /></a> </div>
<div class="thumb"> <a><img src="https://example.com/s/2.jpg" image-file="/image/2.jpg" /> </a> </div>
<div class="thumb"> <a><img src="https://example.com/s/0.jpg" image-file="/image/0.jpg" /> </a> </div>
<div class="thumb"> <a><img src="https://example.com/s/3.jpg" image-file="/image/3.jpg" /> </a> </div>
<div class="thumb"> <a><img src="https://example.com/s/4.jpg" image-file="/image/4.jpg" /> </a> </div>
</div>
'''
soup = bs(html, 'lxml')
links = [item['image-file'] for item in soup.select('#previewImages [image-file]')]
print(links)

如果我們對 lxml 執行相同的場景，則加起來，
import lxml.html
tree = lxml.html.fromstring(sample)
images = tree.xpath("//img/@image-file")
print(images)
輸出 ['/image/15.jpg', '/image/2.jpg', '/image/0.jpg', '/image/3.jpg', '/image/4.jpg']
