* Moved XML_CHILD_HASH to variable instead of constant. * Moved XML_CHILD_HASH to variable instead of constant.
* Added yang to XML API * Changed XML creation and parse API for more coherency and closer YANG/XML integration. A new yang spec parameter has been added (default NULL) and functions have been removed and renamed. You may need to change the XML calls as follows.
* xml_new(name, parent) --> xml_new(name, xn_parent, yspec)
* xml_new(char *name, cxobj *xn_parent) --> xml_new(char *name, cxobj *xn_parent, void *spec) * xml_new_spec(name, parent, spec) --> xml_new(name, parent, spec)
* xml_new_spec(char *name, cxobj *xn_parent, void *spec) --> xml_new(char *name, cxobj *xn_parent, void *spec) * clicon_xml_parse_file(fd, &xt, endtag) --> xml_parse_file(fd, endtag, yspec, &xt)
* clicon_xml_parse_string --> clicon_xml_parse_str * clicon_xml_parse_string(&str, &xt) --> xml_parse_string(str, yspec, &xt)
