How I can do the following block of code from perl to python?

while ($content2 =~ m{services</B></TD>\s<TD>\s<TABLE>\s<TR>(.*?)</TABLE>}gs) {
  my $service=$1
  print " service : $1\n";
}

The full code have more regex outputs than that, but with that example I’m able to proceed with the conversion.

    If i’m reading your regex right, you have a table with a single row (and no data cell) inside a table-data cell. What kind of abomination are you cooking up here?

    In python you’d use lxml for this. It’s a real parser, so it won’t fail when whitespace or casing or other unrelated structure of the document changes. It’s not a part of the standard library, but it’s one of (if not /the/) most-installed libraries on pypi.

    abominable_html = '''
<html>
<table><tr><td>services</B></TD>
    <TD>
        <TABLE> <TR>Interesting stuff!</TABLE>
'''

from lxml.html import fromstring
doc = fromstring(abominable_html)

# These are equivalent, for demonstration purposes.
print doc.xpath('//table/tr/td/table/tr/text()')[0]
print doc.xpath('//table//table/tr')[0].text

    As you can see, it deals with questionable html admirably.

    If you need match the “services” text, you can add a condition like so:

    print doc.xpath('//table[./tr/td="services"]//table/tr')[0].text

    Here are some good xpath references:
