… exist. Element existence is verified by a NULL pointer.
-
Hierarchical element access methods have been added to GXml and GXmlNode.Using a string in the format "params > param[1] > value > struct" one can in a single method call walk down the hierarchy of an XML document to access an element. The squared brackets allow specifying an element index in case that multiple elements with the same name exist. If squared brackets are omitted, an index of 0 is assumed. If the indicated element does not exist, the method returns a pointer to NULL.
-
The coding and design conventions (CDC) document was also updated.
-
Delete statements have been added to the remove() method(s) so that the elements are properly deleted before the pointers are erased.

Add GChatter argument to print() method. The print() method now takes an argument of type GChatter to control the chattiness of the output in a homogenous manner. Pass NORMAL chatter level in __str__ method. Add chatter argument to print() methods. Use GLog::chatter() method to control the chattiness of the log stream operator. Add chatter() methods and provide member access through const references. Add chatter() methods, provide member access through const references, and declare one liners as inline methods. The chatter() methods control the new m_chatter attribute that is used to control the chattiness of the object's print() methods. name() and version() methods return const references. logFileOpen() method now sets the chattiness from the applications's chatter parameter, and name() and version() methods now return a const reference.

The class now derives from GContainer and implements all container class interfaces. Nodes are now passed by reference and cloned internally. This gives full and save memory management to the XML classes.
-
The use of the new GUrl class insread of the FILE type allows now for transparent input and output of an XML document in different URL types. So far only the file type URL exists (GUrlFile), but this can now easily be expanded to support piping into a string or direct http transfer. The latter is particularily useful for XML-RPC implementation.
-
The class is now derived from the GBase class. A print method without argument has been introduced to comply to the GBase standard. The ostream and GLog friends have been removed as printing is now handled by functions operating on GBase.
