-Source, Legals ("Licence")
---------------------------
-The official site to get this parser is http://www.destructor.de/
-
-Usage and Distribution of this Source Code is ruled by the
-"Destructor.de Source code Licence" (DSL) which comes with this file or
-can be downloaded at http://www.destructor.de/
-
-IN SHORT: Usage and distribution of this source code is free.
- You use it completely on your own risk.
-
-Postcardware
-------------
-If you like this code, please send a postcard of your city to my above address.
-===============================================================================================
-!!! All parts of this code which are not finished or not conforming exactly to
- the XmlSpec are marked with three exclamation marks
-
--!- Parts where the parser may be able to detect errors in the document's syntax are
- marked with the dash-exlamation mark-dash sequence.
-===============================================================================================
-Terminology:
-------------
-- Start: Start of a buffer part
-- Final: End (last character) of a buffer part
-- DTD: Document Type Definition
-- DTDc: Document Type Declaration
-- XMLSpec: The current W3C XML Recommendation (version 1.0 as of 1998-02-10), Chapter No.
-- Cur*: Fields concerning the "Current" part passed back by the "Scan" method
-===============================================================================================
-Scanning the XML document
--------------------------
-- Create TXmlParser Instance MyXml := TXmlParser.Create;
-- Load XML Document MyXml.LoadFromFile (Filename);
-- Start Scanning MyXml.StartScan;
-- Scan Loop WHILE MyXml.Scan DO
-- Test for Part Type CASE MyXml.CurPartType OF
-- Handle Parts ... : ;;;
-- Handle Parts ... : ;;;
-- Handle Parts ... : ;;;
- END;
-- Destroy MyXml.Free;
-===============================================================================================
-Loading the XML document
-------------------------
-You can load the XML document from a file with the "LoadFromFile" method.
-It is beyond the scope of this parser to perform HTTP or FTP accesses. If you want your
-application to handle such requests (URLs), you can load the XML via HTTP or FTP or whatever
-protocol and hand over the data buffer using the "LoadFromBuffer" or "SetBuffer" method.
-"LoadFromBuffer" loads the internal buffer of TXmlParser with the given null-terminated
-string, thereby creating a copy of that buffer.
-"SetBuffer" just takes the pointer to another buffer, which means that the given
-buffer pointer must be valid while the document is accessed via TXmlParser.
-===============================================================================================
-Encodings:
-----------
-This XML parser kind of "understands" the following encodings:
-- UTF-8
-- ISO-8859-1
-- Windows-1252
-
-Any flavor of multi-byte characters (and this includes UTF-16) is not supported. Sorry.
-
-Every string which has to be passed to the application passes the virtual method
-"TranslateEncoding" which translates the string from the current encoding (stored in
-"CurEncoding") into the encoding the application wishes to receive.
-The "TranslateEncoding" method that is built into TXmlParser assumes that the application
-wants to receive Windows ANSI (Windows-1252, about the same as ISO-8859-1) and is able
-to convert UTF-8 and ISO-8859-1 encodings.
-For other source and target encodings, you will have to override "TranslateEncoding".
-===============================================================================================
-Buffer Handling
----------------
-- The document must be loaded completely into a piece of RAM
-- All character positions are referenced by PChar pointers
-- The TXmlParser instance can either "own" the buffer itself (then, FBufferSize is > 0)
- or reference the buffer of another instance or object (then, FBuffersize is 0 and
- FBuffer is not NIL)
-- The Property DocBuffer passes back a pointer to the first byte of the document. If there
- is no document stored (FBuffer is NIL), the DocBuffer returns a pointer to a NULL character.
-===============================================================================================
-Whitespace Handling
--------------------
-The TXmlParser property "PackSpaces" determines how Whitespace is returned in Text Content:
-While PackSpaces is true, all leading and trailing whitespace characters are trimmed of, all
-Whitespace is converted to Space #x20 characters and contiguous Whitespace characters are
-compressed to one.
-If the "Scan" method reports a ptContent part, the application can get the original text
-with all whitespace characters by extracting the characters from "CurStart" to "CurFinal".
-If the application detects an xml:space attribute, it can set "PackSpaces" accordingly or
-use CurStart/CurFinal.
-Please note that TXmlParser does _not_ normalize Line Breaks to single LineFeed characters
-as the XmlSpec requires (XmlSpec 2.11).
-The xml:space attribute is not handled by TXmlParser. This is on behalf of the application.
-===============================================================================================
-Non-XML-Conforming
-------------------
-TXmlParser does not conform 100 % exactly to the XmlSpec:
-- UTF-16 is not supported (XmlSpec 2.2)
- (Workaround: Convert UTF-16 to UTF-8 and hand the buffer over to TXmlParser)
-- As the parser only works with single byte strings, all Unicode characters > 255
- can currently not be handled correctly.
-- Line breaks are not normalized to single Linefeed #x0A characters (XmlSpec 2.11)
- (Workaround: The Application can access the text contents on its own [CurStart, CurFinal],
- thereby applying every normalization it wishes to)
-- The attribute value normalization does not work exactly as defined in the
- Second Edition of the XML 1.0 specification.
-- See also the code parts marked with three consecutive exclamation marks. These are
- parts which are not finished in the current code release.
-
-This list may be incomplete, so it may grow if I get to know any other points.
-As work on the parser proceeds, this list may also shrink.
-===============================================================================================
-Things Todo
------------
-- Introduce a new event/callback which is called when there is an unresolvable
- entity or character reference
-- Support Unicode
-- Use Streams instead of reading the whole XML into memory
-===============================================================================================
-Change History, Version numbers
--------------------------------
-The Date is given in ISO Year-Month-Day (YYYY-MM-DD) order.
-Versions are counted from 1.0.0 beginning with the version from 2000-03-16.
-Unreleased versions don't get a version number.
-
-Date Author Version Changes
------------------------------------------------------------------------------------------------
-2000-03-16 HeySt 1.0.0 Start
-2000-03-28 HeySt 1.0.1 Initial Publishing of TXmlParser on the destructor.de Web Site
-2000-03-30 HeySt 1.0.2 TXmlParser.AnalyzeCData: Call "TranslateEncoding" for CurContent
-2000-03-31 HeySt 1.0.3 Deleted the StrPosE function (was not needed anyway)
-2000-04-04 HeySt 1.0.4 TDtdElementRec modified: Start/Final for all Elements;
- Should be backwards compatible.
- AnalyzeDtdc: Set CurPartType to ptDtdc
-2000-04-23 HeySt 1.0.5 New class TObjectList. Eliminated reference to the Delphi 5
- "Contnrs" unit so LibXmlParser is Delphi 4 compatible.
-2000-07-03 HeySt 1.0.6 TNvpNode: Added Constructor
-2000-07-11 HeySt 1.0.7 Removed "Windows" from USES clause
- Added three-exclamation-mark comments for Utf8ToAnsi/AnsiToUtf8
- Added three-exclamation-mark comments for CHR function calls
-2000-07-23 HeySt 1.0.8 TXmlParser.Clear: CurAttr.Clear; EntityStack.Clear;
- (This was not a bug; just defensive programming)
-2000-07-29 HeySt 1.0.9 TNvpList: Added methods: Node(Index), Value(Index), Name(Index);
-2000-10-07 HeySt Introduced Conditional Defines
- Uses Contnrs unit and its TObjectList class again for
- Delphi 5 and newer versions
-2001-01-30 HeySt Introduced Version Numbering
- Made LoadFromFile and LoadFromBuffer BOOLEAN functions
- Introduced FileMode parameter for LoadFromFile
- BugFix: TAttrList.Analyze: Must add CWhitespace to ExtractName call
- Comments worked over
-2001-02-28 HeySt 1.0.10 Completely worked over and tested the UTF-8 functions
- Fixed a bug in TXmlParser.Scan which caused it to start over when it
- was called after the end of scanning, resulting in an endless loop
- TEntityStack is now a TObjectList instead of TList
-2001-07-03 HeySt 1.0.11 Updated Compiler Version IFDEFs for Kylix
-2001-07-11 HeySt 1.0.12 New TCustomXmlScanner component (taken over from LibXmlComps.pas)
-2001-07-14 HeySt 1.0.13 Bugfix TCustomXmlScanner.FOnTranslateEncoding
-2001-10-22 HeySt Don't clear CurName anymore when the parser finds a CDATA section.
-2001-12-03 HeySt 1.0.14 TObjectList.Clear: Make call to INHERITED method (fixes a memory leak)
-2001-12-05 HeySt 1.0.15 TObjectList.Clear: removed call to INHERITED method
- TObjectList.Destroy: Inserted SetCapacity call.
- Reduces need for frequent re-allocation of pointer buffer
- Dedicated to my father, Theodor Heymann
-2002-06-26 HeySt 1.0.16 TXmlParser.Scan: Fixed a bug with PIs whose name is beginning
- with 'xml'. Thanks to Uwe Kamm for submitting this bug.
- The CurEncoding property is now always in uppercase letters (the XML
- spec wants it to be treated case independently so when it's uppercase
- comparisons are faster)
-2002-03-04 HeySt 1.0.17 Included an IFDEF for Delphi 7 (VER150) and Kylix
- There is a new symbol HAS_CONTNRS_UNIT which is used now to
- distinguish between IDEs which come with the Contnrs unit and
- those that don't.
