The above didn't seem to work (with version 1.8.6). I think I have it
working by doing the following:
xmlDocPtr doc = xmlNewDoc((xmlChar*)"1.0");
xmlDtdPtr dtd = xmlParseDTD(NULL, filename_of_dtd);
dtd->name = xmlStrDup((xmlChar*)"root_name");
doc->intSubset = dtd;
doc->children = (xmlNodePtr)dtd;
dtd->doc = doc;
xmlNodePtr root = dtd->next = xmlNewDocNode(doc, NULL, (xmlChar*)"root_name",
NULL);
... Fill in the rest of the nodes off of the root node.
Does this look correct, or am I doing something stupid....
Thanks, Greg
