Problem in appending node to document

[GoogleCodeExporter]

Hi,
I am trying to append node to document but fails.
I have created new document. Creating new node element. Appending one more node 
to this node and then appneding this parent node to document. For this I am 
using append_copy function but fails. Code i am using is as:

   doc.reset(doc);
   childNode = doc.append_copy(child.m_XmlNode);
   child.m_XmlNode = childNode;

Atfer calling reset function, it destroys the tree and replaces it with an 
empty one. If reset function is not called, no node is appended to document.
Please help me.

append_copy will always be able to append the node to the document, as long as 
child.m_XmlNode.type() returns something that's not node_document or node_null. 
Can you confirm the return value of child.m_XmlNode.type()?

Return value of child.m_XmlNode.type() is 2 i.e. node_document.

append_copy can not append the document as a child, since that would result in 
nested documents, which is not allowed.
If the expected type was indeed the document, then you can manually append all 
children like this:

for (pugi::xml_node c = child.m_XmlNode.first_child(); c; c = c.next_sibling())
    doc.append_copy(c);

If, however, you expected child.m_XmlNode to be an element instead of a 
document, you have to check your code to discover why it's not an element.

<node>
  <node1>
    <node2>
    </node2>
  </node1>
<node>
Using code given by you, can we append "node" along with all child nodes?
What about the reset()?

Yes, this code appends the node with all child nodes - note that append_copy 
appends the entire subtree. The reason the loop is necessary at all is to cope 
with document restriction.

doc.reset(doc) is equivalent to doc.reset() and should not be needed unless you 
do want to remove all nodes from the document before proceeding.

If I dont use doc.reset(doc), it is not appending the node. Any solution for 
this?

Normally doc.reset is not needed. I can't think of a case where it would be 
necessary for append_copy to work - can you provide a larger code example that 
exhibits the problem?

I want to create a node in document. And again append that same node in that 
document only. I am using append_child to create node and append_copy to append 
node.
