I'm trying to parse an XML file, I need to be able to pass a single parameter to a batch file "DEV2_BUSINESSAPPS_URL", if found I want the "https://energy.epipelines.com/businessapps/welcome.html" returned. Unfortunately it has to be a batch file.

Here is my XML file:
<Environment>
		<Variable>
			<Name>DEV2_BUSINESSAPPS_URL</Name>
			<Value><![CDATA[https://energy.epipelines.com/businessapps/welcome.html]]></Value>
		</Variable>
		<Variable>
			<Name>DEV3_BUSINESSAPPS_URL</Name>
			<Value><![CDATA[https://energy.epipelines.com/businessapps/welcome.html]]></Value>
		</Variable>
		<Variable>
			<Name>QA1_BUSINESSAPPS_URL</Name>
			<Value><![CDATA[https://qa1comapps.elm.com/businessapps]]></Value>
		</Variable>
		<Variable>
			<Name>Firefox</Name>
			<Value>Firefox.exe</Value>
		</Variable>
</Environment>

A batch (file) is a collection of directives for an interpreter. What interpreter do you have in mind? bash, csh, zsh, 4nt, cmd, ps?

In any scenario you will need an XML parser.
You could write code in your favourite language and run it in batch. Alternatively create a XSLT or Xquery and use an external tool like Saxon to run it.  

Here is an example in python. Python has executables on all platforms.
 
import  xml.etree.ElementTree as  xml

# you should pass is as a parameter
lookup='QA1_BUSINESSAPPS_URL'

# assuming the xml file is called env.xml
e = xml.parse('env.xml').getroot()

# the naive way, but it works
for variable in e.findall("Variable"):
	name=variable.find("Name").text
	value=variable.find("Value").text
	if name==lookup:
		print name, value

# use xpath to search		
for variable in e.findall("./*[Name='%s']" % (lookup) ):
	name=variable.find("Name").text
	value=variable.find("Value").text
	print name, value
