Extract data using HTMLParser

Question

<tr>
  <td style="color: #0000FF;text-align: center"><p>Sam<br/>John<br/></p></td>
</tr>

I am using the python HTMLParser module to extract the values Sam and John from the below html snippet, but the handle_data function is capturing only Sam and not John.

How I can get both Sam and John?

Thanks for your reply. Preferably, because I have completed parsing most of the html document and only this part is remaining. — Vinay

Could you provide a very minimal example depicting your issue ? This would help to fix what might be wrong in your code. — Sylvain Leroux

You can have an instance-level variable that would have True/False values. Set it to True if p tag started, False if p tag ended. When the value is True, get the data in the handle_data() method:

from HTMLParser import HTMLParser

data = """
<tr>
  <td style="color: #0000FF;text-align: center"><p>Sam<br/>John<br/></p></td>
</tr>
"""

class Parser(HTMLParser):
    def __init__(self):
        HTMLParser.__init__(self)
        self.recording = False

    def handle_starttag(self, tag, attrs):
        if tag == 'p':
            self.recording = True

    def handle_endtag(self, tag):
        if tag == 'p':
            self.recording = False

    def handle_data(self, data):
        if self.recording:
            print data

parser = Parser()
parser.feed(data)

Prints:

Sam
John
