comparing domain name in two text files and print in to third one

[srinu_1]

hi,

please help me to solve the error for:

text1.txt:
line1 <data>
line2 <items>
line3 <match name="item1" rhs="domain.com"></match>
line4 <match name="item2" rhs="domainn.com"></match>
line5 <match name="item2" rhs="1010data.com"></match>
line6 </items>
line7 </data>

text2.txt:
line1 djshjsdf
line2 sdfngjfg

check domain.com,domain.com,1010data.com in text2.com, if not there print domain.com,domain.com,1010data.com in to the 3rd text file(text3.txt)

import re
with open('C:\\Users\\Desktop\\m\\test1.txt', 'r') as f_in:
    with open('C:\\Users\\Desktop\\m\\test_compare.txt', 'r') as f_compare:
        with open('C:\\Users\\Desktop\\m\\result.txt', 'w') as f_out:
            d1 = f_in.read()
            d2 = f_compare.read()
            for match in re.finditer(r'rhs="(.*)"', d1):
                    if match not in d2:                         
                            f_out.write('{}\n'.format(match.group(1)))

while running the above code, it throws an error

Traceback (most recent call last):
  File "C:\Python27\comparetwofiles\src\compare\notepadtest.py", line 11, in <module>
    if match not in d2:                         
TypeError: 'in <string>' requires string as left operand, not _sre.SRE_Match

can anyone help me to fix the above error.....

I'm not sure how you're supposedto use re.finditer but not this way. The elements of the returned list are match objects, not strings. I suggest you use findall instead. If I do this:

 lst1=re.findall(r'rhs="(.*)"',d1)

I get this:

['domain.com', 'domainn.com', '1010data.com']

You first post.

You have postet more info about the task,but it still not as clear as it should be.
You can try this.

import re

with open('1.txt') as f1,open('2.txt') as f2,open('result.txt', 'w') as f_out:
    f1 = re.findall(r'rhs="(.*)"', f1.read())
    f2 = re.findall(r'rhs="(.*)"', f2.read())
    diff = [i for i in f1 if i not in f2]
    #print diff
    f_out.write(','.join(diff))
