Xml search for specific node/attribute

Question

Hi,
I load an xml in as3 and need to find and output (as an
XMLList) a specific node with a specific attribute (example:
<xs:element name="abcd"> ), or at least find out its path
(after, I would know what to do to get the XMLList). I looked at
the XPath classes for Actionscript but the documentation is very
poor and I did not see any method doing this. Could someone help me
please? If no method exists, how can I loop through all the xml and
test each node to see if it is the proper node I am looking for?
thanks so much in advance for your help

You could do it this way, using the descendant accessor:
var xml:XML =
<data xmlns:xs="
http://www.w3.org/2001/XMLSchema">
<xs:element name="abcd">
<tagA>hjfhsldf</tagA>
<tagB>dummy stuff</tagB>
</xs:element>
<xs:sequence>
<xs:element name="dd">
<tagA>words</tagA>
<tagB>dummy stuff too</tagB>
</xs:element>
</xs:sequence>
</data>;
var xs:Namespace = xml.namespaceDeclarations()[0];
var nodelist:XMLList = xml..xs::element.(@name=="dd");
trace(nodelist)
If you need generic code that accounts for no namespaces, you
can use
something like this:
var xs:Namespace = xml.namespaceDeclarations()[0];
var nodelist:XMLList =
(xs == null || xs == undefined)
? xml..element.(@name=="dd");
: xml..xs::element.(@name=="dd");
trace(nodelist)
