.handle_comment(data)
This method is called when a comment is encountered (e.g. <!--comment-->).
The data argument is the content inside the comment tag:
from HTMLParser import HTMLParser
class MyHTMLParser(HTMLParser):
def handle_comment(self, data):
print "Comment :", data.handle_data(data)
This method is called to process arbitrary data (e.g. text nodes and the content of <script>...</script> and <style>...</style>).
The data argument is the text content of HTML.
from HTMLParser import HTMLParser
class MyHTMLParser(HTMLParser):
def handle_data(self, data):
print "Data :", dataTask
You are given an HTML code snippet of lines.
Your task is to print the single-line comments, multi-line comments and the data.
Print the result in the following format:
>>> Single-line Comment
Comment
>>> Data
My Data
>>> Multi-line Comment
Comment_multiline[0]
Comment_multiline[1]
>>> Data
My Data
>>> Single-line Comment: Note: Do not print data if data == '\n'.
Input Format
The first line contains integer , the number of lines in the HTML code snippet.
The next lines contains HTML code.
Constraints
Output Format
Print the single-line comments, multi-line comments and the data in order of their occurrence from top to bottom in the snippet.
Format the answers as explained in the problem statement.
Sample Input
4
<!--[if IE 9]>IE9-specific content
<![endif]-->
<div> Welcome to HackerRank</div>
<!--[if IE 9]>IE9-specific content<![endif]-->Sample Output
>>> Multi-line Comment
[if IE 9]>IE9-specific content
<![endif]
>>> Data
Welcome to HackerRank
>>> Single-line Comment
[if IE 9]>IE9-specific content<![endif]Solution in python3#
Approach 1.
from html.parser import HTMLParser
class MyHTMLParser(HTMLParser):
def handle_comment(self, data):
prefix = '\n' in data and 'Multi-line Comment' or 'Single-line Comment'
print('>>> {0}\n{1}'.format(prefix, data))
def handle_data(self, data):
if data is not '\n':
print('>>> Data\n{0}'.format(data))
html = ""
for i in range(int(input())):
html += input().rstrip()
html += '\n'
parser = MyHTMLParser()
parser.feed(html)
parser.close()Approach 2.
from html.parser import HTMLParser
html = ""
class MyHTMLParser(HTMLParser):
def handle_comment(self,data):
if('\n' in data):
print(">>> Multi-line Comment")
else:
print(">>> Single-line Comment")
print(data)
def handle_data(self,data):
if(data != '\n'):
print(">>> Data")
print(data)
for i in range(int(input())):
html += input().rstrip()
html += '\n'
#print(html)
parser = MyHTMLParser()
parser.feed(html)
parser.close()Approach 3.
from html.parser import HTMLParser
class MyHTMLParser(HTMLParser):
def handle_comment(self, data):
if data.count('\n') == 0:
print('>>> Single-line Comment')
else:
print('>>> Multi-line Comment')
print(data)
def handle_data(self, data):
if data.strip() != '':
print('>>> Data')
print(data)
html = ""
for i in range(int(input())):
html += input().rstrip()
html += '\n'
parser = MyHTMLParser()
parser.feed(html)
