This is particularly for Harbs and Yishay, as I think you are both (or both
have been) using XML quite a bit. I have quite a few fixes coming. All
with tests that match on swf and js.
I am currently working to demonstrate proof of concept to a prospective
client for migration of a Flex app. The app makes extensive use of e4x and
uses a bunch of features that I expect had not received attention
previously, because they were originally either not working with the
codebase I am porting, or i think some even caused errors in the javascript
output.
So I have spent the last several days almost full time figuring things out
and working on fixes, between the compiler and emulation classes.
All the previous XML tests continue to pass, but I have many more unit
tests and fixes lined up for the following:
namespace directives
default xml namespace
use namespace (multiple)
a number of fixes for xml filtering, including:
-'this' resolves correctly in filters that include external references from
the fitler expression to the 'this' scope
-handles alternate ordering of comparisons between XML 'getters' and
literals
e.g. something.(name() = "cat") or something.("cat" = name()) (these are
the same)
-it (will) now handle XML e4x references in nested function calls inside
the filter, e.g. things like:
e.g.
var people:XML = <people>
<person>
<name>Bob</name>
<age>32</age>
</person>
<person>
<name>Joe</name>
<age>46</age>
</person>
</people>;
var findJoeByAge:Function = function (i:int):Boolean {
return i > 40;
};
people.person.(findJoeByAge(parseInt(age))).name
I have lots more granular tests in QName, Namespace, and XML with tuning to
improve reliability.
toXMLString XML node output also matches flash more correctly in what I
have coming.
One thing that I am trying to figure out, which I would appreciate input on
if someone has an answer:
For the example:
var feed:XML = new XML(
'<feed xmlns:atom="http://www.w3.org/2005/Atom";
xmlns:m="nothing">\n' +
' <link rel="no_namespace"
href="blah/12321/domain/"/>\n' +
'</feed>\n');
var atomSpace:Namespace = new Namespace('http://www.w3.org/2005/Atom');
Can anyone explain why this (in SWF, as a reference implementation):
trace(feed.atomSpace::link.length())
trace(feed.atomSpace::link.toXMLString())
//output:
0
{empty string}
is different to:
trace(feed.child(new QName(atomSpace,'link')).length())
trace(feed.child(new QName(atomSpace,'link')).toXMLString())
//output:
1
<link rel="no_namespace" href="blah/12321/domain/" xmlns:atom="
http://www.w3.org/2005/Atom"; xmlns:m="nothing"/>
I had assumed the above cases would be the same, but the second one is
behaving as if it has the default namespace included with the specified
namespace in the QName matching (it does correctly match the namespace
specifically as well -with e.g. <atom:link nodes where the prefix atom is
bound to the uri, but also seems to include link nodes with the default
namespace, whether or not it is declared). I can accommodate this
difference to make them behave the same, I just would like to understand
the basis for the actual rules if anyone knows....
I should be in a position to push the updates this coming weekend I think.
