I'm not sure that this actually solves the stated problem though as I =
think I am right in saying that this is a fix that goes into get_file(). =
 Therefore if the datastructure can't describe =
"Before<tag>Middle</tag>End", then it's not going to be able to print =
it.

This fix will cope with usage of the object that make calls to =
set_content("address","Some text <B>that</B> contains some markup.").  =
But if the xml file that you read in already has "Some text <B>that</B> =
contains some markup." then the class is going to loose this structure =
in the parse.

Basically phpxml's internal datastructure is lossy.  You can't read to =
object and write back out to file and have two logically identical =
files.  Ideally it ought to be.

We need a more complete fix for this in the constructor or =
load_from_file function I think....
