我有一个文件,其中包含以下类型的数据
A 1 2 3
B 2 2 2
c 2 4 5
d 4 5 6
从上面的文件中,我想执行类似的循环,
三次迭代,其中第一次迭代将具有A,B元素;第二次迭代将具有c个元素,第三次迭代将具有d。这样我的html表格就会变成
Week1 | week2 | week3
----------------------------
A 1 2 3 | c 2 4 5 | d 4 5 6
B 2 2 2
我在catch multiple empty lines in file in tcl中找到了这个,但是我没有得到我想要的。
答案 0 :(得分:1)
我建议使用数组:
# Counter
set week 1
# Create file channel
set file [open filename.txt r]
# Read file contents line by line and store the line in the varialbe called $line
while {[gets $file line] != -1} {
if {$line != ""} {
# if line not empty, add line to current array with counter $week
lappend Week($week) $line
} else {
# else, increment week number
incr week
}
}
# close file channel
close $file
# print Week array
parray Week
# Week(1) = {A 1 2 3} {B 2 2 2}
# Week(2) = {c 2 4 5}
# Week(3) = {d 4 5 6}
