Re: [xml] xmlNewTextWriterTree, writerTree

[David Wimsey <dwimsey rtsz com>]

You are creating two root elements, which is not valid XML.  You'll need 
to do something like:

The resulting XML file will look something like:

void
testXmlwriterTree(const char *file)
{
   xmlTextWriterPtr writer;
   xmlDocPtr doc;
   xmlNodePtr node;

   // tested on the version 2.6.26
   doc = xmlNewDoc(BAD_CAST XML_DEFAULT_VERSION);
   node = xmlNewDocNode(doc, NULL, BAD_CAST "Alivemessage", NULL);

   xmlDocSetRootElement(doc, node);

   writer = xmlNewTextWriterTree(doc, node, 0);

   xmlTextWriterStartDocument(writer, NULL, MY_ENCODING, NULL);

   xmlTextWriterStartElement(writer, BAD_CASE "DocumentRoot"); // Starts a toplevel element named Document 
root

   xmlTextWriterStartElement(writer, BAD_CAST "HEADER");      // this goes inside DocumentRoot
   xmlTextWriterEndElement(writer);

   xmlTextWriterStartElement(writer, BAD_CAST "ENTRIES");     // this goes inside DocumentRoot, but after 
HEADER
   xmlTextWriterEndElement(writer);

   xmlTextWriterEndElement(writer);     // ends DocumentRoot

   xmlTextWriterEndDocument(writer);

   xmlFreeTextWriter(writer);

   xmlSaveFileEnc(file, doc, MY_ENCODING);

   xmlFreeDoc(doc);
}

The resulting XML file will look something like:

<?xml version="1.0" encoding="utf-8" ?><DocumentRoot><HEADER/><ENTRIES/></DocumentRoot>
