Traversing XML structures: Performance question

programming flash
1

Dear all,

I just want to ask you if these statements are equal from a performance perspective.

var myXML:XML=
<catalogue>
<groups>
<movie id=“0” name=“mc1” x=“0” y=“0” />
<movie id=“1” name=“mc2” x=“192” y=“0”/>
<movie id=“2” name=“mc3” x=“96” y=“0” />
<movie id=“3” name="mc3 x=“448” y=“0” />
</groups>
</catalogue>

Statement 1
myXML.groups[2];

Statement 2
myXML.groups.(@id ==2);

In my scenery, I got 1000 lines in the XML.
Sorry to ask, but I do not know how to measure them.

Thanks in advance
