Filtering an XMLListCollection using the filterFunction property and regular expressions

Filtering an XMLListCollection using the filterFunction property and regular expressions: "
Here is another handy little tip that you see all over the web, how do I filter a data grid (or other list-based control) based on a user’s input? Or more specificially, how to I limit the items that show in a list based on what a user types.

Since I already created a simple XML document of Countries/States, I thought I’d create a basic form that lets a user type in the first few characters of a state name and have the DataGrid filter its results. You’ll also notice that I had to do some not-so-tricky E4X filtering to extract only the American state names.

Full code after the jump.
