Re: Re: [xml] child nodes disappear after call to xmlNodeSetContent()

danilo,


thanks a lot for your reply, this put me on the right track!


i changed the calls to xmlSetNodeContent on the element-nodes to



      xmlNodePtr textNode1 = xmlNewText(BAD_CAST "content");
      xmlAddChild(node_c, textNode1);

      xmlNodePtr textNode2 = xmlNewText(BAD_CAST "a's content");
      xmlAddChild(node_a, textNode2);


and now it behaves correctly!


assuming i have a class which wraps an xmlNodePtr, i could automatically
create an aditional empty textnode for every element node. if i want set or
change the content, i call xmlSetNodeContent on the underlying textnode and
it should work. am i right in this point?


best wishes


markus
