I followed your tips Kiel,
I downloaded the code of libxml2 vers. 2.6.26, and I changed into the module xmlsave.c, the method xmlNodeDumpOutputInternal.
Tthe problem is related to the setting of the "format" parameter:
format = ctxt-> format;
if (format == 1)
{
tmp = cur-> children;
while (tmp! = NULL)
{
if ((tmp-> type == XML_TEXT_NODE) | |
(tmp-> type == XML_CDATA_SECTION_NODE))
{
-------->>>>>>>>>> / / (Tmp-> type == XML_ENTITY_REF_NODE)) {
ctxt-> format = 0;
break;
}
tmp = tmp-> next;
}
}
I commented out the line :
(Tmp-> type == XML_ENTITY_REF_NODE)
and I compiled the library and installed, it seems that now everything is OK ........
What do you think?

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.

<example>
&xml; <example1> text </ example1> <example2> text </ Example2> </ example>
instead of:

</ Example2>
</ example>

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++.

I'm using libxml + + library in C + +, and I have to write an xml file in which there is an inclusion of another xml file:

Can you help ?
