从文本中删除引号

Question

我正在尝试从以下字符串变量中删除引号：

* Example generated by -dataex-. To install: ssc install dataex
clear
input str46 mags
`"Automotive" News"""'                            
"Automobile"                                      
`""Aviation Week and Space Technology""'          
`"Technical Analysis "of Stocks "& Commodities"""'
`""Bloomberg""" Businessweek""'                   
end

但是，我得到一个错误：

replace mags = subinstr(mags, """, "", .)
too few quotes
r(132);

我的代码有什么问题？

Answer 1

您需要在subinstr()函数中使用 compound 双引号：

generate wanted = subinstr(mags, `"""', "", .)

list wanted
