Removing all caps words from string variable

[Alex Paige]

Hello, I am looking for help with syntax that will remove any all caps words from a string variable "about" but does not remove a word if just one letter is capitalized. For example, in the sentence, "I NEED help" the word "NEED" would be removed but "I" would not. Can anyone help with this?

I is usually capitalized and is one word. You may want to enforce the restriction that the to be removed word is at least 2 characters long.

* Example generated by -dataex-. To install: ssc install dataex
clear
input str11 text
"I need help"
"I NEED help"
"I Need Help"
"I NEEd hELP"
end

gen wanted= trim(itrim(ustrregexra(" "+text+ " ", "\s[A-Z]{1}[A-Z]+\s", " ")))

     +---------------------------+
     |        text        wanted |
     |---------------------------|
  1. | I need help   I need help |
  2. | I NEED help        I help |
  3. | I Need Help   I Need Help |
  4. | I NEEd hELP   I NEEd hELP |
     +---------------------------+
