grep was born to extract things:

grep -Po 'name="\K[^"]*'

test with your data:

kent$  echo '<parameter name="PortMappingEnabled" access="readWrite" type="xsd:boolean"></parameter>
  <parameter name="PortMappingLeaseDuration" access="readWrite" activeNotify="canDeny" type="xsd:unsignedInt"></parameter>
  <parameter name="RemoteHost" access="readWrite"></parameter>
  <parameter name="ExternalPort" access="readWrite" type="xsd:unsignedInt"></parameter>
  <parameter name="ExternalPortEndRange" access="readWrite" type="xsd:unsignedInt"></parameter>
  <parameter name="InternalPort" access="readWrite" type="xsd:unsignedInt"></parameter>
  <parameter name="PortMappingProtocol" access="readWrite"></parameter>
  <parameter name="InternalClient" access="readWrite"></parameter>
  <parameter name="PortMappingDescription" access="readWrite"></parameter>
'|grep -Po 'name="\K[^"]*'
