Accessing Atom XML entry by id?

Question

Hello,
I have a strange problem when trying to access atom feeds (or
any xml really).
I'm using a standard HttpService to grab an atom feed, then
i'm trying to access a particular node summary from its id with
this xml query:
myLabel.text=myFeed..entry.(id=="elementidhere").summary;
But it will not match any entry based on the id, yet it will
quite happily match against the title or any other node as such:
myLabel.text= myFeed..entry.(title=="Welcome").summary;
And will even output the id just to prove it exists:
myLabel.text= myFeed..entry.(title=="Welcome").id;
Is there something special about the id node so I cant do a
straightforward match against it- I'm using the atom namespace
which reports the id as a uri so do I need to handle it
differently. I've tried converting it to a string also, but this
then throws an error saying its null:
myLabel.text=myFeed..entry.(id.toString()=="tag:elementid").summary;
Any ideas?

Use this as your schema. It should work then.
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:complexType name="EntryClass">
<xsd:attribute name="ID" type="xsd:ID" use="required"/>
<xsd:attribute name="value" type="xsd:string" use="required"/>
</xsd:complexType>
<xsd:complexType name="MapClass">
<xsd:sequence>
<xsd:element maxOccurs="unbounded" minOccurs="1" name="entry" type="EntryClass"/>
</xsd:sequence>
</xsd:complexType>
<xsd:element name="map" value="MapClass"/>
