Thanks for your help. Anyway I just found the documentation to the automation and scripting docs at the top of the respective forum's webpage.

I used your suggestion and can now iterate the NSArray. But the NSArray contains items of NSRange. I don't know how to access each item's properties. I currently have this code set matchRanges to (urlRegex's matchesInString:(theText) options:(0) range:({0, theText's |length|()}))'s valueForKey:("range") set matchRangesCount to count of matchRanges repeat with idx from 1 to matchRangesCount set element to (matchRanges's objectAtIndex:idx) set position to element's location set theSize to element's length end repeatBut the element's location and element's length properties cannot be accessed this way. What is the proper way to access the structs members ? Thanks, Regards

my mistake. I had an error in the use of shell variables
