Try as I may, I cannot seem to grab the value of the "Id" attribute in the nested apcmroperty element, where the "Name" attribute equals "sequenceNumber", on line 12. As you can see, there element of interest is buried in a nest of other elements with an identical name and namespace.Using PHP, I'm having a difficult time wrapping my head around how to grab that Id value.\[code\]<?xml version="1.0" encoding="utf-8" ?><feed xmlns="http://www.w3.org/2005/Atom" xmlns:apcm="http://ap.org/schemas/03/2005/apcm" xmlns:apnm="http://ap.org/schemas/03/2005/apnm" xmlns:georss="http://www.georss.org/georss"> <id>urnublicid:ap.org:30085</id><title type="xhtml"> <apxh:div xmlns:apxh="http://www.w3.org/1999/xhtml"> <apxh:span>AP New York State News - No Weather</apxh:span> </apxh:div></title><apcmroperty Name="FeedProperties"> <apcmroperty Name="Entitlement" Id="urnublicid:ap.orgroduct:30085" Value="http://stackoverflow.com/questions/10725355/AP New York State News - No Weather" /> <apcmroperty Name="FeedSequencing"> <apcmroperty Name="sequenceNumber" Id="169310964" /> <apcmroperty Name="minDateTime" Value="http://stackoverflow.com/questions/10725355/2012-05-22T18:04:18.913Z" /> </apcmroperty></apcmroperty><updated>2012-05-22T18:04:18.913Z</updated><author> <name>The Associated Press</name> <uri>http://www.ap.org</uri></author><rights>Copyright 2012 The Associated Press.
