BonoboUINode* bonobo_property_bag_xml_encode_any (BonoboUINode *opt_parent, const |
This API is really super simple. It is designed in conjuction with the BonoboUINode API to allow you to serialize a BonoboArg ( in fact a CORBA_any ) to an XML format, and obviously the converse.
Here is a code sample to produce an XML string from a CORBA_any or BonoboArg:
Example 1. Converting Any to XML
char *
convert_arg_to_xml (BonoboArg *bonobo_arg)
{
CORBA_Environment ev;
BonoboUINode *node;
char *value;
CORBA_exception_init (&ev);
node = bonobo_property_bag_xml_encode_any (NULL, bonobo_arg, &ev);
if (!node)
return NULL;
value = bonobo_property_bag_xml_decode_any (node, &ev);
bonobo_ui_node_free (node);
CORBA_exception_free (&ev);
return value;
}

Here is the converse sample to produce a BonoboArg from an XML string:
Example 2. Converting XML to an Any
BonoboArg *
convert_xml_to_arg (const char *xml)
{
CORBA_Environment ev;
BonoboUINode *node;
BonoboArg *value;
CORBA_exception_init (&ev);
node = bonobo_ui_node_from_string (xml);
if (!node)
return NULL;
value = bonobo_property_bag_xml_decode_any (node, &ev);
bonobo_ui_node_free (node);
CORBA_exception_free (&ev);
return value;
}

BonoboUINode* bonobo_property_bag_xml_encode_any (BonoboUINode *opt_parent, const |
This routine encodes any into an XML tree using the BonoboUINode XML abstraction. ev is used for flagging any non-fatal exceptions during the process. On exception NULL will be returned. opt_parent should be NULL, and is used internally for recursive tree construction.
Both type and content data are dumped in a non-standard, but trivial format.
| opt_parent : | optional parent, should be NULL |
| any : | the Any to serialize |
| ev : | a corba exception environment |
| Returns : | the XML tree representing the Any |
|
This routine is the converse of bonobo_property_bag_xml_encode_any. It hydrates a serialized CORBA_any.
| node : | the parsed XML representation of an any |
| ev : | a corba exception environment |
| Returns : | the CORBA_any or NULL on error |
