What I want is this:
<tree>
<objects>
<object id="12345678">
<AdditionalInfo>
<Owner>Mr. Heik</Owner>
<Health>37/100</Health>
</AdditionalInfo>
</object>
</objects>
</tree>
What I get is this:
<tree>
<objects>
<object id="12345678"/>
<AdditionalInfo>
<Owner>Mr. Heik</Owner>
<Health>37/100</Health>
</AdditionalInfo>
</objects>
</tree>
What I tried is this:
using boost::property_tree::ptree;
ptree pt;
boost::property_tree::ptree nodeObject;
nodeObject.put("object.<xmlattr>.id", 12345678);
boost::property_tree::ptree nodeInfo;
nodeInfo.put("Owner", "Mr. Heik");
nodeInfo.put("Health", "37/100");
// Put everything together
nodeObject.put_child("AdditionalInfo", nodeInfo);
pt.add_child("tree.objects", nodeObject);
write_xml("output.xml", pt);
I tried to get the desired result by using put/add/add_child/etc. but without success. Which boost-functions do I have to use?

This line :
nodeObject.put("object.<xmlattr>.id", 12345678);
Is adding a new child to the subpath "object" of the current node with the given attribute.
Just set your attribute on the Node:
nodeObject.put("<xmlattr>.id", 12345678);
And add the node directly to the correct path in your tree:
pt.add_child("tree.objects.object", nodeObject);
Final code :
ptree pt;
boost::property_tree::ptree nodeObject;
nodeObject.put("<xmlattr>.id", 12345678);
boost::property_tree::ptree nodeInfo;
nodeInfo.put("Owner", "Mr. Heik");
nodeInfo.put("Health", "37/100");
nodeObject.put_child("AdditionalInfo", nodeInfo);
pt.add_child("tree.objects.object", nodeObject);
write_xml("output.xml", pt);
Output :
<?xml version="1.0" encoding="utf-8"?>
<tree>
<objects>
<object id="12345678">
<AdditionalInfo>
<Owner>Mr. Heik</Owner>
<Health>37/100</Health>
</AdditionalInfo>
</object>
</objects>
</tree>
