Thanks Gerry and Deepanjan...
I found a solution, but I'm completely puzzled why it worked and the obvious
E4X statement you both suggested didn't work. I seem to be getting unreliable
results. Maybe it's some logic about the statements I am missing. I don't
understand why it all can't be done in one statement, I get null for that.

<asset title="Document 1" fileName="a.mpg"/>
<asset title="Document 2" fileName="b.mpg"/>
</topic>
//doesn't work for me
topic..asset.(hasOwnProperty("@title") && attribute("title") ==
wording)....@filename<mailto:....@filename>
// unreliable. Sometimes it works, sometimes it doesn't. Is it a bug? I'm not
seeing things. :)
var d:XMLList = thisTopic..*.(hasOwnProperty("@title") && @title == wording);
// doesn't work...why?
var assets:XMLList = topic..asset.(hasOwnProperty("@title") &&
attribute("title") == wording);

Deepanjan...this solution worked too.
Did you try this:
var topic:XML = topicData[0]; // gets the below xml, came from an xmllist
var wording:String = "Presentation";
var assets:XMLList = topicData[0]..asset;
trace(assets.(@title == wording));
I have an E4X statement that breaks when I add a filter to it to get a specific
node. I keep getting null when I include hasOwnProperty() to the statement.
// I want to get "giraffe.ppt" or <asset title="Presentation"
fileName="giraffe.ppt"/>
var topic:XML = topicData[0]; // gets the below xml, came from an xmllist
var wording:String = "Presentation";
// I get an xmllist for this:
var assets:XMLList = topicData[0]..asset;
// but I keep getting null returned for these:
var assets:XMLList = topicData[0]..asset.(hasOwnProperty("@title"));
var assets:XMLList = topic..asset.(hasOwnProperty("@title") &&
attribute("title") == wording)....@filename;
Why does the statement break with the E4X filter?
