Problem with XML attributes in AS3.0

Table of contents for flex-tips
- Problem with XML attributes in AS3.0
- Unable to export SWC oem
- Numeric sorting of Flex DataGridColumn
I’ve found today some small problem with setting XML attribute for my current application. I’m generating HTML source code via XML, because both are tags languages and I have found this nice problem. Imagine you have DIV tag with class attribute set like this:
<div class="myClass">test</div>
So in ActionScript 3 you can create it via XML in this way
var divXML:XML = <div>test</test>; divXML.@class = "myClass";
All seems ok and trivial, but Flex Builder has problem to compile second line. It seems that @class is reserved word, because I can change to other attribute name and it works. But luckily there are different ways how to set XML attribute for XML node. I’ve fixed it in this way
var divXML:XML = <div>test</test>; divXML.@["class"] = "myClass";
What is your preffered way to set XML attributes?

I like setting attributes inline. If the XML block to to be made into a child, I’ll use appendChild on the parent XML.
var className:String = “myClass”;
var divXML:XML = <div class={className}>test</div>;

surely, this would break in XML also for example
<xtag class=”blergh”>
</xtag>
not just HTML?
because they are both the same. sorry, its just I got the picture from your post that this only breaks in HTML and Flex not XML and Flex.

Oh, sorry, my preffered way is the second using the array/string notation

Btw. Empty tag is another issue I’m experiencing when generating HTML from XML in AS3.0. I will create new post about this, but in short term. If you have empty div and it is written in way
You can see example in this comment, all after <STRONG/> is bolded, which is really awkward…

I think the problem with closed tags like <strong/> instead of <strong></strong> is that xml doesn’t support that so trying to do in xml just breaks it. I think the solution would be to find the source of the XML class, and edit to support the full HTML spec.

dont you think that the simple fact that your html is screwed up,
test looks nicer than test, dont you think ?
