在新行上不拆分(’n’)

为什么这个字符串不在每个“ n”上分开? (RUBY) 

"ADVERTISING [7310]\n\t\tIRS NUMBER:\t\t\t\t061340408\n\t\tSTATE OF INCORPORATION:\t\t\tDE\n\t\tFISCAL YEAR END:\t\t\t0331\n\n\tFILING VALUES:\n\t\tFORM TYPE:\t\t10-Q\n\t\tSEC ACT:\t\t1934 Act\n\t".split('\n')
>> ["ADVERTISING [7310]\n\t\tIRS NUMBER:\t\t\t\t061340408\n\t\tSTATE OF INCORPORATION:\t\t\tDE\n\t\tFISCAL YEAR END:\t\t\t0331\n\n\tFILING VALUES:\n\t\tFORM TYPE:\t\t10-Q\n\t\tSEC ACT:\t\t1934 Act\n\t"]

You need .split("\n"). String interpolation is needed to properly interpret the new line, and double quotes are one way to do that.

You can't use single quotes for this:

"ADVERTISING [7310]\n\t\tIRS NUMBER:\t\t\t\t061340408\n\t\tSTATE OF INCORPORATION:\t\t\tDE\n\t\tFISCAL YEAR END:\t\t\t0331\n\n\tFILING VALUES:\n\t\tFORM TYPE:\t\t10-Q\n\t\tSEC ACT:\t\t1934 Act\n\t".split("\n")

In Ruby single quotes around a string means that escape characters are not interpreted. Unlike in C, where single quotes denote a single character. In this case '\n' is actually equivalent to "\\n".

So if you want to split on \n you need to change your code to use double quotes.

.split("\n")

Ruby has the methods String#each_line and String#lines

returns an enum: http://www.ruby-doc.org/core-1.9.3/String.html#method-i-each_line

returns an array: http://www.ruby-doc.org/core-2.1.2/String.html#method-i-lines

I didn't test it against your scenario but I bet it will work better than manually choosing the newline chars.

Or a regular expression

.split(/\n/)
