Possibly, but might be easier to use something like python or perl, as 
then end result is going to be a channel change script I guess.
This python code might do the trick.


import  httplib,  urllib
import  re
  
conn=  httplib.HTTPConnection("http://xxx.xxx.xxx.xx  <http://xxx.xxx.xxx.xx/>:49153/SkyPlay2")
XML='*****XMLSTUFF Goes Here *****'
headers=  {  "SOAPACTION: urn:schemas-nds-com:service:SkyPlay:2#SetAVTransportURI",  "content-type: text/xml", "charset=utf-8"}
conn.request("POST",  params,  "",  headers)
conn.send(XML)
response=  conn.getresponse()
print  response.status,  response.reason
  
print  response.read()
conn.close()
