Manipulate XML document and change content in Zend Framework

[olebiri]

I'm building an application on Zend Framework and now there is requirement to manipulate a xml file and change few content of it so that I could use the xml as a request file to get a response from other server. Now after a googling I've seen popularity of simplexml over others but I'm not sure which implementation would be better for Zend Framework. Any suggestions would be very helpful.My request XML file is like this:\[code\]<?xml version="1.0" encoding="UTF-8"?> <aa> <bb> <cc> <dd> <ee/> </dd> <ff> <Identification _FirstName="******" _LastName="*****" _Num="********"> <gg/> </Identification> </ff> </cc> </bb> </aa>\[/code\]Now, I need to be able to change the value of _FirstName, _LastName and Num. Which XML manipulation method should I use with Zend Framework for this and how?Thanks in advance.
