[xml] Use of the "&" character in the content of a Node

[Unai Astorquiza]

Hi,

I've a question about the "&" character.

  nodePtr = xmlNewNode(NULL, "node");
  if (nodePtr)
  {
    xmlNodeSetContent(nodePtr, "111&222");
  }

At this point, the content of the node has been set to "111"

If I put the ampersand as &, the resulting node content is "111&222"

Which is the correct way to put the content "111&222" in the node? I mean, to 
get the following result:

<node>111&222</node>

I want to be able to set it, and get it back later.

Do I have to create a new text node (xmlNewText) instead of using xmlNewNode? 

Thanks in advance for your help,

Unai Astorquiza
