Actually I'm parsing a file with parseFile().

But the string consists of 3 line and for the second line I created
a parser with LineStart() and LineEnd(). That's why I'm using 
LineStart() to get the beginning of the second line. Is this wrong?

What puzzles me is that the parser yields the correct results, as long
as no actions are attached to it. At least it's the result I expected.
But after adding setParseAction() it is no longer working.


Maybe I should explain my original case: I try to parse a file which has
/one/ particular line containing a few numbers separated by spaces. I do
not know how many numbers there are in this line. I just know that they
are in this particular line. Thus I need to take care about linebreak
in this line. For the rest of the file (before and after this line) I
do not need to (and don't want to) take care about linebreaks.
