按列而非按行读取文本

Java Read Text Column function similar to ReadLine()

I have a text file containing vector information by pin. It looks like this:

PHP Code:

xxxxxxxxxxxxxxxxxxxx 
pppppppppppppppppppp 
iiiiiiiiiiiiiiiiiiii 
nnnnnnnnnnnnnnnnnnnn 
12345689111111111122 
012345678901 
 
 
 
 
CountPatAdr 
(Main)(Main) 
101000000000000010XXXX 
201000000000000010XXXX 
301000000000000010XXXX 
401000000000000010XXXX 
501000000000000010XXXX 
601000000000000010XXXX 
701000000000000010XXXX 
801000000000000010XXXX 
901000000000000010XXXX 
1001000000000000010XXXX 
1101000000000000010XXXX 
1201000000000000010XXXX 
1301000000000000010XXXX 
1401000000000000010XXXX 
1501000000000000010XXXX 
1601000000000000010XXXX 
... 

I want to extract the information column by column. So I would like to be able to write or store each pin by line such as:
xpin1 11111...
xpin2 10000...
xpin3 10000...
Basically, what I am looking for is exactly the Java readLine() function described here:
http://java.sun.com/javase/6/docs/ap...redReader.html
but instead of reading a text file line-by-line. I want to read column by column. Anyone know of such a function or way to do this?

       要实现这个算法，需要进行集合成员的拼接和转换。java做这种集合式的运算不难，但代码繁琐比较麻烦；使用 R 或 python 都比较容易，但没法被 java 主程序集成。用 SPL 也容易完成，并且可以被 java 主程序调用 (参考Java 如何调用 SPL 脚本)，代码如下：

	A
1	=file("source.txt").read@n()
2	=A1.to(2,6)
3	=A1.to(14,)
4	=A2.regex("(.*) (.*)";a,b).(b)
5	=A4.new(mid(~,1,1),mid(~,2,1),mid(~,3,1),mid(~,4,1),mid(~,5,1),mid(~,6,1),mid(~,7,1),mid(~,8,1),mid(~,9,1),mid(~,10,1),mid(~,11,1),mid(~,12,1),mid(~,13,1),mid(~,14,1),mid(~,15,1),mid(~,16,1),mid(~,17,1),mid(~,18,1),mid(~,19,1),mid(~,20,1))
6	=A3.regex("(.*) (.*)";a,b).(b)
7	=A6.new(mid(~,1,1),mid(~,2,1),mid(~,3,1),mid(~,4,1),mid(~,5,1),mid(~,6,1),mid(~,7,1),mid(~,8,1),mid(~,9,1),mid(~,10,1),mid(~,11,1),mid(~,12,1),mid(~,13,1),mid(~,14,1),mid(~,15,1),mid(~,16,1),mid(~,17,1),mid(~,18,1),mid(~,19,1),mid(~,20,1))
8	=A5|A7
9	=A8.fno().(A8.field(~).concat())

A1：读取source.txt文件内容,将每一行返回成字符串。

A2：取序列第2-6行数据组成新序列。

A3：取14行之后的数据组成新序列。

A4：正则匹配出需要的数据。

A5：将A4拆分成二维表。

A6：正则匹配出需要的数据。

A7：将A6拆分成二维表。

A8：合并2个二维表。

A9：将每列合并成字符串。
