The Document::write_*_formatted() methods turn off formatting in an
element that contains a child node of type TextNode, CdataNode, or
EntityReference, and recursively in all the element's child
elements. It's not libxml++'s fault. It's how the underlying libxml2
functions behave.
I have not found this behaviour documented anywhere. I had to check
libxml2's source code to understand what's going on. If you're
interested, look at
http://git.gnome.org/browse/libxml2/tree/xmlsave.c function
xmlNodeDumpOutputInternal() line 944. (The line number may change,
if the file is edited.) Obviously the behaviour is by design.
Probably we have to accept it. If you think it's worth the trouble,
you can file a libxml2 bug. At least it would be fine to have the
behaviour documented.
Of course you can get the output you want by adding text nodes with
all the linefeeds and spaces that you want, but it would be tedious.

Tested,
but the output is
not formatted
:
<example>
&xml; <example1>
text </ example1> <example2> text

instead of:

I think something is missing in xmlpp::Element. There is no way to
create an xmlpp::EntityReference or an
xmlpp::ProcessingInstructionNode. (They can be created when
you parse an xml file, but I can find no way to create an xml
file with those nodes without resorting to functions in the
underlying libxml2.)
In the attached small program I have added an
add_child_entity_reference() function. Then it's possible to
write the file you want. I recommend that you file a bug on
libxml++.
