Using xmlNodeSetContent() with text nodes and with element nodes i get a different behaviour.

With this fragment of C code

--- begin C code fragment ---

   nChild1 = xmlNewChild(nRoot, NULL, BAD_CAST "child1", NULL);
   nChild2 = xmlNewChild(nRoot, NULL, BAD_CAST "child2", NULL);
   nText2  = xmlNewText(NULL);

   xmlAddChild(nChild2, nText2);

   xmlNodeSetContent(nChild1, BAD_CAST "&");
   xmlNodeSetContent(nText2,  BAD_CAST "&");

--- end C code fragment ---


i obtain the following result


--- begin result ---

  <child1>&amp;</child1>
  <child2>&amp;amp;</child2>

--- end result ---

According to the documentation "content" (the second argument of xmlNodeSetContent()) "is supposed to be a piece of XML CDATA, so it allows entity references, but XML special chars need to be escaped first"

I suppose the correct behaviour is with element nodes.

Doubt: is correct to use xmlNodeSetContent() with text nodes?
