	Hello all,

should not 
	        consider that line. It should just print the content of
that line 
	        and continue parsing the next line. How to do this

If "TE_" really can appear anywhere on a physical line, there's no way
to do this with ANTLR or similar tools. You'd have to write a simple
preprocessor that just reads the file a line at a time, searches the
line
for "TE_", and throws the line away if it's found.

Or, just use:
$ grep -v "TE_" myfile
