I have this regex to look at an Apache log.
There are modules to help with that task on CPAN.
m/^(\S+) \S+ \S+ \[(\d{2})\/(\S+)\/(\d{4}):.+\] "(\w+) (\S+)
([^"]+)" (\d{3}) (\d+|-) ".+"$/;
Would like to set it out in a bit more readable form a la Perl Cook Book and
others
eg
m/
^(\S+) # Comment
\S+ # Comment
\S+ # Comment
etc,
but "they don't work" and I suspect it is something to do with the spaces
between the elements. I have even tried specifying spaces with \s
The key is to use the /x modifier on the end of the regex to allow this
type of formatting. You then, according to perldoc perlretut, can either
backslash "real" spaces or put them in a character class. See,
perldoc perlretut
for more.
Can someone give me a pointer as to how to go about this.
