This is my first post to SoPW, though I've had solid success using the CB.
I work with lots of text files and have had problems with the perl mods ie Text::CSV_XS etc... do not allow for embedded non-escaped text qualifiers or field seperators. So this is an attempt to retrieve the text qualifier and field seperator from a text file containing a header.
$foo = qq{^snafu^|^foobar^\n};
$foo =~ m/\A(\W) # \A instead of ^ and match first non-word
[^\1]+ # Match everything that isn't in \1
\1(\W) # Match non-word following the 2nd \1
/xms;
$text_qual = $1;
$field_sep = $2;
The regular expression is setting the second match to newline instead of pipe as it should.
It appears as if
[^\1]+ is being interpreted as
.+ for some reason?
Obviously in this case I could use
$foo =~ m/\A(\W) # \A instead of ^ and match first non-word
\w+\1 # Match any word char until the next \1
(\W) # Match following non-word
/xms;
But this only works for this limited case where the first field contains no symbols. Any suggestions would be greatly appreciated.
