I’m a Flash Developer, and I parse XML all the time. Your a Flash Developer, and you potentially parse XML all the time.
I’m not sure how you handle schema’s, but typically I’m making up the XML format as I go, and since the structure isn’t memorized, I’ll typically either open it up on Dreamweaver or Notepad, start coding my parser in Flash, and toggle back and forth when I need to refresh my memory on what the XML I’m parsing looks like.
For smaller chunks, I can just paste an example in my code, and refer to it that way.
…both ways suck. So, I created this panel that allows you to load text into it. I then can load my XML file into it, dock the panel, and refer to it while I’m coding. You can load any text file, but typically one would use it for XML files.
I hope this helps your productivity, too!
