Um. I did that;

Sorry but you didn't. You posted some data and a pattern you say you want to match the data but it doesn't match -- great, now show your code that uses the pattern with this data that fails to match

it works "perfectly" as expected

Compiling REx "\<\/div\>\n\<\/body\>"
Final program:
   1: EXACT <</div>\n</body>> (6)
   6: END (0)
anchored "</div>%n</body>" at 0 (checking anchored isall) minlen 14
Guessing start of match in sv for REx "\<\/div\>\n\<\/body\>" against 
+"</div>%n</body>"
Found anchored substr "</div>%n</body>" at offset 0...
Guessed: match at offset 0
Freeing REx: "\<\/div\>\n\<\/body\>"
