I enjoy using XSLT only for changing the tree structure of XML documents. I find it cumbersome to do anything related to text processing and relegate that to a custom script that I may run before or after applying an XSLT to an XML document.
XSLT 2.0 included a lot more string functions, but I think it's not a good... |

The box model is usually the culprit. Basically what this means is that any div you are trying to position and use unsupported CSS with will cause this problem.

StringBuilder is preferable *IF* you are doing multiple loops, or forks in your code pass... however, for PURE performance, if you can get away with a *SINGLE* string declaration, then that is much more performant.

Python doesn't force you on using "self". You can give it whatever name you want. You just have to remember that the first argument in a method definition header is a reference to the object. |
I think you can just drag them into the library of your main swf and make references to them. At least the other SWFs you can, not sure about the CSS and XML. |
In an application I worked on, the Last name field was considered reliable.

Well, in practice it is rarely an issue. Usually the different team members are working on different areas of the code, so there is no conflict.

Order of DOM NodeList returned by getChildNodes() |

The DOM method `getChildNodes()` returns a `NodeList` of the children of the current `Node`. Whilst a `NodeList` is ordered, is the list guaranteed to be in document order?

I'd love to tell you that this is guaranteed (as I believe it is) but the [Document Object Model specification][1] itself seems ambiguous in this case. I'm pretty sure that it's always document-order, though.
