나는 왜 입장에 액세스 할 수 없는지 알아 내려고 몇 시간 동안 책상에서 머리를 두드려 왔습니다. 가능한 모든 방법을 시도해 보았지만 실패했습니다.
그러나 xml.children을 사용하여 모든 노드를 살펴보면 저자 노드가 나타납니다.
저자 노드가 원자 네임 스페이스와는 별개로 표시되지만 다른 네임 스페이스와 같은 네임 스페이스가 없습니다.

해결책
이 시도 ...
public function Gdata()
{
var atom:Namespace = new Namespace("http://www.w3.org/2005/Atom");
var media:Namespace = new Namespace("http://search.yahoo.com/mrss/");
var gd:Namespace = new Namespace("http://schemas.google.com/g/2005");
var yt:Namespace = new Namespace("http://gdata.youtube.com/schemas/2007");
default xml namespace = atom; // IMPORTANT
trace("0",xml.children()[22]);
trace("1",xml.inScopeNamespaces());
trace("2",xml..media::group);
trace("3",xml..yt::statistics.@favoriteCount);
trace("4",xml..yt::duration.@seconds);
trace("5",xml..author ); // why?????????
trace("6",xml.author ); // why?????????
var x:int = 0;
for each (var i in xml.children())
{
if(i.localName() == 'author')
{
trace("author", i);
}
}
}
다른 팁
네임 스페이스를 완전히 제거 할 수도 있습니다 ... 여기에 내가 찾은 최상의 솔루션이 있습니다 (네임 스페이스 세부 정보를 속성으로 바꿉니다).
public function removeNS(data:XML):XML {
var myXML;
try {
var modified:String = data.toString().replace("xmlns=", "xmlns:default=");
var pattern:RegExp = new RegExp(":(?!/)", "gi");
var transmuted:String = modified.replace(pattern, "_");
myXML = new XML(transmuted);
} catch (e:Error) {
myXML = data;
}
return myXML;
}
MXML 파일 어딘가에 다음 코드 스 니펫이 필요합니다 (XML 문서로 작업하기 전에)
