Answer 1

您可以使用Python的字符串函数来提取它。

清理后的字符串将如下所示“NH-16 in Andhra Pradesh Stretch :”

我只是使用 .index() 查找“in”的索引(6)和“Stretch”的索引(25)，然后使用 获取索引 6 到 25 的文本text[onset + 2:offset] - 这是 Python 版本的子字符串。如果您需要澄清，请告诉我。

text = search1[1].get_text()
onset = text.index('in')
offset = text.index('Stretch')
name = str(text[onset + 2:offset]).strip(' ')
print name
