How to extract contents of inner text of html tag?

[Golam Md. Shibly]

Hi,

###in.txt
<kbd class="command">
cp -v --remove-destination /usr/share/zoneinfo/
<em class="replaceable"><code><xxx></code></em>
\
/etc/localtime
</kbd>

import sys
import unicodedata
from bs4 import BeautifulSoup

file_name="in.txt"
html_doc=open(file_name,'r')
soup=BeautifulSoup(html_doc)
#print soup.prettify().encode('utf-8')
#file_to_write.writelines( soup.prettify().encode() )

all_kbd=soup.find_all('kbd')

for line in all_kbd:
if line.string == None:
extract_code=line.code.extract().string
#store_code=line.code.decompose()
for inside_line in line:
if "<<" not in inside_line and "EOF" not in inside_line:
if len(inside_line)>0:
print inside_line
print extract_code

expected output:
cp -v --remove-destination /usr/share/zoneinfo/<xxx>\
/etc/localtime


Got output:
cp -v --remove-destination /usr/share/zoneinfo/

None

\
/etc/localtime

None
