我的源程序是这样的
#include<libxml/parser.h>//使用libxml库
#include<libxml/tree.h>
int main(int argc, char** argv)
{
      xmlDocPtr doc = NULL;    /* document pointer */
      xmlNodePtr root_node = NULL, node = NULL, node1 = NULL;/* node pointers */
// Creates a new document, a node and set it as a root node
      doc = xmlNewDoc(BAD_CAST "1.0"

;
root_node = xmlNewNode(NULL, BAD_CAST "root"

;
      xmlDocSetRootElement(doc, root_node);
      //creates a new node, which is "attached" as child node of root_node node.
      xmlNewChild(root_node, NULL, BAD_CAST "node1",BAD_CAST "content of node1"

;
// xmlNewProp() creates attributes, which is "attached" to an node.
node=xmlNewChild(root_node, NULL, BAD_CAST "node3", BAD_CAST"node has attributes"

;
xmlNewProp(node, BAD_CAST "attribute", BAD_CAST "yes"

;
//Here goes another way to create nodes.
node = xmlNewNode(NULL, BAD_CAST "node4"

;
node1 = xmlNewText(BAD_CAST"other way to create content"

;
      xmlAddChild(node, node1);
      xmlAddChild(root_node, node);
      //Dumping document to stdio or file
      xmlSaveFormatFileEnc(argc > 1 ? argv[1] : "-", doc, "UTF-8", 1);
      /*free the document */
      xmlFreeDoc(doc);
      xmlCleanupParser();
      xmlMemoryDump();//debug memory for regression tests
      return(0);
}
