If a string and the HTML::Entities-decoded result of the string are the same, it is no HTML entity.

    #!/usr/bin/perl; use HTML::Entities; $to_decode = "TEST&TEST;A&E&an HTML--- string - <© T +VS>"; $encoded = encode_entities($to_decode); print "Encoded data --> $encoded\n\n\n";
    The output is Encoded data --> TEST&TEST;A&E&an HTML--- string - <© TVS> Here all the & is replaced with &. If it is a HTML entity it should not encode the string for ex:   Here it displays as   it should be   only

      I don't understand what your reply has to do with the original question of finding out whether a string is an HTML entity and my reply on how to detect whether a string is an HTML entity.

        For example : If the string contain $a= &foo foo When I encode it using the function encode_entities($a); The   should not be encoded. So the final output after encoding should be &foo foo Now the output is &foo foo. So I wanted to check it the string is HTML entity?
