Step 2 In getfirstparagraph() we invoke re.match. The pattern matches the start and the end of the string with metacharacters.
Step 3 We check the returned match value, and then access the first group (which is text from the first parenthesis grouping).
# Step 2: call re.match.# Capture the characters within the p tags.# Match the start and end of the html string.
m = re.match(r"^.*<p>\s*(.+?)\s*</p>.*$", html)
# Step 3: return first group item if groups exists.
return ""# Step 1: specify html string and call getfirstparagraph method.
html = r"<html><title>...</title><body><p>Result.</p></body></html>"
Some notes. Trying to access text from within HTML using Python regular expressions may not be ideal, but it usually works. There can be problems with comments, or mixed-case HTML tags.
So Be careful not to apply this style of code to all HTML documents, just a known set of them where it matches correctly.
Summary. HTML is everyone in the modern world, and Python is often used to extract text from external documents. With this logic, we can fetch at least some paragraph text.
