XML in a .log file

I have a .log file that is update every 15 minutes on my server, from communication with some mobile units.

Some of the information is text and some xml.

How can I extract the xml, i have tried excel but returns errors, have tried parsing also returns errors.

The data returned looks similar to this for each unit returned every 15 minutes, so by end of day quite a lot of mixed text and xml.
