What really worries me is that apparently if i use XMLList for parsing
the doc (i have to, as i need the PI) i can't access the default
namespace via namespaceDeclarations().
XML.ignoreProcessingInstructions = false;
var a:XMLList = XMLList(
'<?xml-stylesheet href="my.css" type="text/css"?>' +
'<root xmlns="http://example.com/"; />');
trace(a.toXMLString());
// <?xml-stylesheet href="my.css" type="text/css"?>
// <aaa:root xmlns:aaa="http://example.com/"/>
trace(XML(a[1]).namespace());
// http://example.com/ (correct)
trace(XML(a[1]).namespaceDeclarations().length);
// 0 (wrong. this should be 1)
If i explicitly give my root element a prefix, like so:
XML.ignoreProcessingInstructions = false;
var a:XMLList = XMLList(
'<?xml-stylesheet href="my.css" type="text/css"?>' +
'<xyz:root xmlns:xyz="http://example.com/"; />');
Everything is fine:
trace(a.toXMLString());
// <?xml-stylesheet href="my.css" type="text/css"?>
// <xyz:root xmlns:xyz="http://example.com/"/>
trace(XML(a[1]).namespace());
// http://example.com/ (correct)
trace(XML(a[1]).namespaceDeclarations().length);
// 1 (correct)
As soon as a default namespace declaration is involved, it is ignored by
namespaceDeclarations(). That's also probably why toXMLString() invents
a prefix in that case (same for xml:id attributes, because there is no
declaration for the xml prefix, as it is implicitly defined).
Plus, all of this does not happen when i parse with XML() rather than
XMLList(). But then i can't access the PI.
Afaik this is a bug.
Cheers,
Claus.
