How to get all text between two specified tags using BeautifulSoup?

html = """
...
<tt class="descname">all</tt>
<big>(</big>
<em>iterable</em>
<big>)</big>
<a class="headerlink" href="#all" title="Permalink to this definition"></a>
...
"""

I want to get all the text between the bigupto start tag before the tag first appears a. This means that if I take this example, then I should get (iterable)as a string.

I would avoid nextSibling, since from your question you want to include everything until the next <a>, regardless of whether it is in a sibling, parent or child.

, , node, <a>, , . , , HTML , - :

from bs4 import BeautifulSoup
#by taking the `html` variable from the question.
html = BeautifulSoup(html)
firstBigTag = html.find_all('big')[0]
nextATag = firstBigTag.find_next('a')
def loopUntilA(text, firstElement):
    text += firstElement.string
    if (firstElement.next.next == nextATag):             
        return text
    else:
        #Using double next to skip the string nodes themselves
        return loopUntilA(text, firstElement.next.next)
targetString = loopUntilA('', firstBigTag)
print targetString

.

from BeautifulSoup import BeautifulSoup as bs
from itertools import takewhile, chain

def get_text(html, from_tag, until_tag):
    soup = bs(html)
    for big in soup(from_tag):
        until = big.findNext(until_tag)
        strings = (node for node in big.nextSiblingGenerator() if getattr(node, 'text', '').strip())
        selected = takewhile(lambda node: node != until, strings)
        try:
            yield ''.join(getattr(node, 'text', '') for node in chain([big, next(selected)], selected))
        except StopIteration as e:
            pass

for text in get_text(html, 'big', 'a'):
    print text
