Title: Removing all HTML tags from a string.
Question: I was developing a web application, where I received strings from a HTML form. There was a problem: if the user entered any HTML tags, the resulting web page could be not what I wanted it to be.
I had no time and lust to put an array of all HTML tags in my application... so I tryed to do that only seeking for ""... it works!
Answer:
That's the simply solution to the problem presented:
Function RemoveHTMLTags( FromWhere : String ) : String;
Var
IdX : Integer;
IdY : Integer;
ForceExit : Boolean;
Begin
Result := FromWhere;
ForceExit := False;
Repeat
IdX := Pos( ' IdY := Pos( '', Result );
If ( ( IdX 0 ) And ( IdY IdX ) ) Then Begin
Result := Copy( Result, 1, ( IdX - 1 ) ) + Copy( Result, ( IdY + 1 ), MaxInt );
End Else Begin
ForceExit := True;
End;
Until ( ( IdX = 0 ) Or ( IdY = 0 ) Or ( ForceExit ) );
End;
Other solutions are wellcome!
