、どのようにhrefタグの前www.example.comを追加し、すべての<a href="" title="">抽出するために、正規表現や美しいスープを使用して：

www.example.com/loads/data/usersindex.cfm?event=overview.subprocess&ApplNo=114223 | title= | Click to view LEMONS (LEMONS) | POQ #114223 | BOX;67 PZ | PRESENTATION | FRUIT COMPANY 1 | LEMONS (LEMONS)

for a in soup.tbody.findAll('a', href=True): 
    r = re.compile('(?<=href=").*?(?=")') 
    r.findall(str(a) 

そして：私がしようとした

for a in soup.tbody.findAll('a', href=True): 
    print (a.find('a')['href']) 
    print (a.find('a')['title']) 

しかし、タイトルと階層をどのように再配置するかはわかりません。 odradekの答えに基づいて UPDATE

、私はこれを試してみました：

soup = BeautifulSoup(open('file.htm'), 'lxml') 
for a in soup.tbody.findAll('a', href=True): 
    html = a 
    PREFIX = 'www.example.com' 
    template = '{prefix}{url} | {title}'.format 
    links = [template(prefix=PREFIX, url=e['href'], title=e['title']) for e in html.find_all('a', href=True)] 
    print(links) 

は、しかし、私が得た：

Answer 1

あなたの代わりに、このために複雑な正規表現のBeautifulSoup解析メソッドを使用することができます。

# this is the url you want to add at the beginning 
PREFIX = 'www.example.com' 

# the template of your desired output 
template = '{prefix}{url} | {title}'.format 

# the resulting list, please note that "html" variable is 
# the given source code. 
links = [template(prefix=PREFIX, url=e.get('href'), title=e.get('title')) 
     for e in html.find_all('a', href=True)] 

あなたのリストの2個のaタグに対して実行したとき：あなたの更新に基づいて

$ python get_all_a.py 
www.example.com/loads/data/usersindex.cfm?event=overview.subprocess&ApplNo=117511 | Click to view GRAPES (GREEN GRAPES ; AUS) | POQ #117511 | BOX;67 PZ | PRESENTATION | FRUIT COMPANY 11

、あなたではなく、forループその内のコードのこの部分を置くべきではありません。

html = BeautifulSoup(open('file.htm'), 'html.parser') 

PREFIX = 'www.example.com' 

template = '{prefix}{url} | {title}'.format 

# inside this list comprehension is your for loop implied 
links = [template(prefix=PREFIX, url=e.get('href'), title=e.get('title')) 
     for e in html.find_all('a', href=True)] 

Answer 2

はこれが仕事ではありません正規表現のために。

from lxml import etree 

tree = etree.fromstring(html) 
for element in tree.xpath('//a'): 
    print('www.example.com' + element.get('href')) 
    print('title: ' + element.get('title'))
