how to read data from the xml in pi

Hello Experts ,

I am having http to rfc asynchronous scenario . As scenario is asynchronous , third party is not able to understand whether all data  has come to pi or not . So we are thinking of writing a simple report(in se 38) in pi which will send a mail to third party people saying this are the order numbers which PI has received. For that we need to read data from the XMLs in sxmb_moni as order numbers are located inside xml . Can any one tell me how we can read xmls in abap language and use the data inside xml?

Regards ,
