问题
I have the following XML document:
<tt xmlns="http://www.w3.org/ns/ttml" xmlns:tts="http://www.w3.org/ns/ttml#styling" xml:lang="en">
<head></head>
<body>
<div xml:lang="it">
<p begin="00:00:00" end="00:00:02" style="violet">first</p>
</div>
</body>
</tt>
I load the contents into my flash object using AS3 successfully. But how do print/trace the value of the attribute in <div xml:lang="it">? When I try the code:
trace(myxml.children()[1].children()[0].@xml:lang);
The compiler complains about the syntax error presented by the colon.
回答1:
In your xml there is no 'xml' namespace. Probably you missed it. Should be something like this:
<tt xmlns:xml="http://blabla.com" ... xml:lang="en">
Then you need to declare Namespace instance for accessing xml attributes, tags for that namespace:
var ns:Namespace = new Namespace("xml","http://blabla.com") ;
Then you can use this code to access attribute:
trace(myxml.children()[1].children()[0].@ns::lang);
回答2:
Perhaps use:
.attribute('xml:lang') instead of .@xml:lang

回答3:
Use ::.
.@xml::lang
