But...the contents of the node1 element is everything between <node1> 
and </node1>, so that's what you would expect the dump routine to show.

You can write your own routine that just displays the element name and 
all of its attributes. That's not too hard.

Here is a method that I use to visit all of the attributes of an element 
and make a callback for each of them. Just ignore the callback related 
stuff and look at how it iterates over the attributes. For each of them, 
it extracts the name and value and puts them into the params structure 
that it passes to the callback. You could do a printf in the inner loop 
using pAttr->name and pChild->content, if that's all you're after.
        
//----------------------------------------------------------------------------
void
XmlLibraryAdapter::elementNodeAttributeVisitor (
     xmlNodePtr pNode,
     XmlLibraryAdapterAttributeVisitorCallback_T *pCallback,
     void *pPrivate) const
{
     xmlAttr *pAttr = NULL;
     XmlLibraryAdapterAttributeVisitorCallbackParams_T params;
     params.pPrivate = pPrivate;
     for (pAttr = pNode->properties; pAttr; pAttr = pAttr->next)
     {
         params.attributeName = (const char *)pAttr->name;
         if (pAttr->ns)
        {   // Attribute is in a namespace, so we need the name
             // string to contain the namespace prefix.
             assert (pAttr->ns->prefix);
             std::string attrName ((const char *)pAttr->ns->prefix);
             attrName += ":";
             attrName += (const char *)pAttr->name;
             params.attributeName = attrName.c_str();
         }
                
         xmlNode *pChild = pAttr->children;
         assert (pChild);
         params.attributeValue = (const char *)pChild->content;
                        
         (*pCallback) (&params);
     }
}
