Using Python and Beautifulsoup we can find any HTML element by partial or exact text value using find / find_all method by passing regular expressions object to the text parameter:
python
import re
import bs4
soup = bs4.BeautifulSoup('<a>Twitter link</a>')
# case sensitive:
soup.find("a", text=re.compile("Twitter")) # will find 1st ocurrance
soup.find_all("a", text=re.compile("Twitter")) # will find all ocurrances
# case insensitive:
soup.find("a", text=re.compile("twitter", re.I))
soup.find_all("a", text=re.compile("twitter", re.I))
