Flash _url text file

I have text file named _url
It is working properly as follows:

url1=http://www.MyWebSite.com/text/page1.html

I want to add the following but don't know the correct way for this text file:

url1=http://www.MywebSite.com/text/page1.html target="_blank" rel="nofollow"

I know how to do this in HTML but not in this text directory file.

url1 is coded in a flash file but I only see movie clip. Do see a way in modifying it here. I am using flash 8.

This is what I found in flash:
on (rollOver) {
gotoAndPlay("s1");
}
on (rollOut, releaseOutside) {
gotoAndPlay("s2");
}
on (release) {
if(_root.url1==""|| _root.url1== undefined){
getURL("javascript:alert('NO URL1!')")
}
else{
getURL(_root.url1,"_self")
}
}
