Lua字符串模式

我正在尝试解析一个字符串，但我不熟悉模式匹配。

这是我的代码：

str = "One[0:0,0,0,0,0,0,0,0,0,0,0,0:1][0:1,0,1,0,0,0,1,1,1,0,0,0:0.5]/Two[0:0,0,0,0,0,0,0,0,0,0,0,0:1.5]/"

for i in string.gmatch(str, "[%a%s]*[%[%]%d:,]*/") do
print("sequence: "..i)
end

它应该打印：

One[0:0,0,0,0,0,0,0,0,0,0,0,0:1][0:1,0,1,0,0,0,1,1,1,0,0,0:0.5] Two[0:0,0,0,0,0,0,0,0,0,0,0,0:1.5]

但它打印：

sequence: 5]/ sequence: 5]/
