I would like to find exact match for items from tuple. Why does my code return True for all lines? I want it to return false. Any ideas? What am I doing wrong?



test1.xml - 
<field1ff>1</field1ff>
<field1ff>1</field1ff>
<field2ff>1</field2ff>
<field2ff>1</field2ff>




fields_to_find = {"<field1>","<field2>"}

file = open("test1.xml", "r")
for line in file.readlines():
if (s in line for s in fields_to_find):
print("true")

    XML is a structured format and should not be processed like that for line in file.readlines():. Use a proper xml/html markup parser

You are passing a generator object to your if statement, for which the boolean evaluation is True:



bool((s in line for s in fields_to_find))


Returns:



True


Instead, IIUC you can use any() and pass your generator:



any(s in line for s in fields_to_find)


Returns:



False
