lua 字符串分隔，支持以单个字符或字符串进行分隔

local function explode ( _str, seperator)

local pos, arr = 0, {}

for st, sp in function() return string.find( _str, seperator, pos, true ) end do

table.insert(arr, string.sub(_str, pos, st-1 ))

pos = sp + 1

end

table.insert(arr, string.sub( _str, pos))

return arr

end

local ta2 = explode("hsee_,sdj_,ehi_,djsd","_,")

local newSt2 = table.concat(ta2,"\n")

print(newSt2)
