The following code is a brief example of sorting a Flex XMLListCollection using the Sort and SortField classes, and the XMLListCollection.sort property. We also look at filtering the XMLCollection using a custom filter function.

It looks like I forgot to post this and I’ve had this as a draft for a week. I was looking at creating a regular expression for validating a UPS tracking number and/or InfoNotice number and decided to do a quick RegExp for validating a Canadian postal code instead. Fear not, my 3 loyal readers, I’ll post the other regular expressions later on.

Another example of something I’ve seen lately on the Internet, so I thought I’d build it in Flex. This time I usea TitleWindow to display the status message of a login form. You can close the message by clicking the X button in the upper-right corner of the title window.
Note that there is no correct login. It will display the error message every time. In a future example I’ll try and add some fancy fade in/out effects or resize effects on the error message to give it that proper “Web 2.0 feel”.

This is always a neat trick that I seem to always forget about, so I thought I’d post it here. When working with Regular Expressions, the RegExp class supports named groups. So instead of having to go through the RegExp result and access it like an array ([1], [2] .. [n]), you can use named results. Long story short, it can make working with the results a bit more intuitive. I made a simple example below which parses the user’s Flash Player version and displays the operating system/platform, major revision, minor revision, build number and internal build number.

Just a quick example I threw together last night which loads the Kuler RSS feed and displays some items in a DataGrid along with their rating and theme image (using the Flex Image control as a custom item renderer).
