Flash as code tip: function to remove annotations

function | The trick function is as follows:
Remove notes and trailing spaces, www.fanflash.cn
Private Function DeleteComment (dt:string): string{
var mark:string= "'"
var newstr:string;

Remove annotations
var markid:number=dt.lastindexof (mark,dt.length);
if (markid==-1) {
NEWSTR=DT; No comment
}else{
Newstr=dt.slice (0,markid); Have comments
}

Remove spaces
var len:number=newstr.length;
var Deleteid:number=len//position with no white space characters
for (Var i=len-1;i>=0;i--) {
if (Newstr.charat (i)!= "") {
Deleteid=i;
Break Jump out of the loop
}
}
Return Newstr.slice (0,deleteid+1);
Example
For example, the name of a STRING,STR is AA:
----------------------------------------------------------------------------------
http://localhost/videoboard/saveimage/' Save the address of the picture folder
http://localhost/videobard/aspx/' script file file parity address
------------------------------------------------------------------------------------
You can use the above function in this way:
Private Function Analyzestext (dt:string) {
var txtarr:array=dt.split ("\ n");
var len:number=txtarr.length
for (Var i=0;i<len;i++) {
Trace (This.deletecomment (txtarr[i]));
}

And then execute this. Analyzestext (AA), you can output each line of the corresponding no comment no trailing space of STR

What is this function for?
I am writing a program configuration file, with XML too cumbersome, data redundancy is too large, the simplest is the configuration of the variable written in a row, but also afraid that others can not understand the meaning of this row variable, so add a comment after the variable, but to the program inside the annotation must be removed, so there is the above function.
