[GB.XML] OPT : A few compilation optimizations in headers inclusions. OPT : Use of separated internal classes of gambas objects. This might prevent from a lot of problems. OPT : Strings are not stored as wchar_t* anymore, but as simple char*, and are converted only when necessary (like UTF8 characters verification). OPT : Does not use STL classes anymore. They are too slow. Uses now handmade classes. OPT : Nodes are now internally linked to their brothers, so it makes find them really fasters, and allows no longer use of external linked list. OPT : When creating new nodes, linked Gambas objects are created only when necessary, so it makes internals instanciations very faster (such as the parser). OPT : Handmade string/memory classes and functions are now separated from the main.cpp component file. OPT : Use specialized memory management functions (like memcpy, memchr ...) into the parser. They are really faster than C loops, and speeds up the parser for documents that have a lot of plain text. OPT : Internally, the stream parser (XmlReader) takes only one char, not a unuseful wole string object. OPT : Does not updates debugging data when parsing a file. They will be generated only if an error is raised (not implemented yet). It will allow a speedier parser and more precise informations. BUG : When loading a document from a file, now correctly releases the file data. BUG : Solved a few XmlReader uninitialized variables, that could make the stream parser crash or returns strange results. git-svn-id: svn://localhost/gambas/trunk@4737 867c0c6c-44f3-4631-809d-bfa615b0a4ec

[GB.XML] * NEW : Added a new property "State" to XmlExplorer and XmlReader, that allows to know the reader state, without knowing Read() return value. * NEW : When enumerating XmlReader.Node.Attributes, XmlReader.Node represents the current attribute. * NEW : Added an new method Open() that loads an HtmlDocument from a file and defines it as the document to read. * NEW : The Attributes property has now moved from XmlElement to XmlNode. XmlNode.Attributes returns Null if the node isn't an element. * NEW : Then enumeration of XmlNode.Attributes now returns an .XmlElementAttribute instead of a string. * NEW : The XmlNode.Attribute constant is not obsolete anymore. * NEW : Two consecutives whitespaces are now ignored (only one is preserved). * NEW : When parsing a file, line-breaks and tabulations are replaced by spaces. * BUG : XmlExplorer flags are now correctly initialized. * BUG : Added an Eof property on XmlExplorer, that was missing. * BUG : Calling XmlExplorer.Read() after Eof just returns XmlReaderNodeType.Eof, not more. * BUG : Calling XmlNode.Next() when the node hasn't got any brother after him doesn't crash anymore, it just returns Null. * BUG : Calling XmlElement.NextSibling() when the node hasn't got any element brother after him doesn't crash anymore, it just returns Null. * BUG : By default, XmlReader correctly stops when reading the end of an element. * BUG : XmlExplorer now correctly initializes and releases itself. * BUG : XmlExplorer now correctly supports its read flags. * OPT : Solved a memory leak when releasing a XmlReader. * OPT : When setting text content to a XmlNode, the string is not duplicated anymore. * OPT : When testing if characters are whitespaces or names characters while parsing texts, puts the temporary variable into registers instead of memory. git-svn-id: svn://localhost/gambas/trunk@4669 867c0c6c-44f3-4631-809d-bfa615b0a4ec
