24. " key: " <<iter->first<<
26. Xmlnewtextchild (Root, NULL, Bad_cast (*iter). First.c_str (), Bad_cast (*iter). SECOND.C_STR ());
28. }
32. //save XML   
36. int  nrel = xmlsavefile (Filename.c_str (), doc);   
40. if   (nrel != -1)   
44. " Create a xml: " <<NREL<< " bytes " <<ENDL;&NBSP;&NBSP;
46. //debuglog (" create a xml %d bytes\n ", NRel); &NBSP;&NBSP;
48. }
