        Be aware using the last libxml2 version. I've tried the example
below linking against 2.6.7 and, as espected, xmlNewText() has escaped
built-in entities.
        Within xmlNewTextChild()'s guts it uses xmlNewText(). :)
        
#include <stdio.h>
#include <libxml/tree.h>
#include <libxml/parser.h>

int
main (int argc, char **argv)
{
  xmlDocPtr doc;
  xmlNodePtr text_node, child_node, root_node;

  doc = xmlNewDoc ("1.0");
  root_node = xmlNewNode (NULL,"root");
  xmlDocSetRootElement (doc, root_node);

  child_node = xmlNewNode (NULL, "child");
  xmlAddChild (root_node, child_node);

  text_node = xmlNewText ("escaped & < >");
  xmlAddChild (child_node, text_node);
  xmlNewTextChild (root_node,NULL, "child","escaped & < >");

  xmlSaveFormatFileEnc ("-", doc, "UTF-8", 1);
  xmlFreeDoc (doc);
}
