/*
The main class of this module, MyMoneyGncReader, contains only a readFile()
function, which controls the import of data from an XML file created by the
current GnuCash version (1.8.8).
The XML is processed in class XmlReader, which is an implementation of the TQt
SAX2 reader class.
Data in the input file is processed as a set of objects which fortunately,
though perhaps not surprisingly, have almost a one-for-one correspondence with
KMyMoney objects. These objects are bounded by start and end XML elements, and
may contain both nested objects (described as sub objects in the code), and data
items, also delimited by start and end elements. For example:
<gnc:account> * start of sub object within file
<act:name>Account Name</act:name> * data string with start and end elements
...
</gnc:account> * end of sub objects
A GnuCash file may consist of more than one 'book', or set of data. It is not
clear how we could currently implement this, so only the first book in a file is
processed. This should satisfy most user situations.
GnuCash is somewhat inconsistent in its division of the major sections of the
file. For example, multiple price history entries are delimited by <gnc:pricedb>
elements, while each account starts with its own top-level element. In general,
the 'container' elements are ignored.
XmlReader
This is an implementation of the TQt TQXmlDefaultHandler class, which provides
three main function calls in addition to start and end of document. The
startElement() and endElement() calls are self-explanatory, the characters()
function provides data strings. Thus in the above example, the sequence of calls
would be
startElement() for gnc:account
startElement() for act:name
characters() for 'Account Name'
endElement() for act:name
...
endElement() for gnc:account
Objects
Since the processing requirements of XML for most elements are very similar, the
common code is implemented in a GncObject class, from which the others are
derived, with virtual function calls to cater for any differences. The
'grandfather' object, GncFile representing the file (or more correctly, 'book')
as a whole, is created in the startDocument() function call.
The constructor function of each object is responsible for providing two lists
for the XmlReader to scan, a list of element names which represent sub objects
(called sub elements in the code), and a similar list of names representing data
elements. In addition, an array of variables (m_v) is provided and initialized,
to contain the actual data strings.
Implementation
Since objects may be nested, a stack is used, with the top element pointing to
the 'current object'. The startDocument() call creates the first, GncFile,
object at the top of the stack.
As each startElement() call occurs, the two element lists created by the current
object are scanned.
If this element represents the start of a sub object, the current object's subEl()
function is called to create an instance of the appropriate type. This is then
pushed to the top of the stack, and the new object's initiate() function is
called. This is used to process any XML attributes attached to the element;
GnuCash makes little use of these.
If this represents the start of a data element, a pointer (m_dataPointer) is set
to point to an entry in the array (m_v) in which a subsequent characters() call
can store the actual data.
When an endElement() call occurs, a check is made to see if it matches the
element name which started the current object. If so, the object's terminate()
function is called. If the object represents a similar KMM object, this will
normally result in a call to a conversion routine in the main
(MyMoneyGncReader) class to convert the data to native format and place it in
storage. The stack is then popped, and the parent (now current) object notified
by a call to its endSubEl() function. Again depending on the type of object,
this will either delete the instance, or save it in its own storage for later
processing.
For example, a GncSplit object makes little sense outside the context of its
transaction, so will be saved by the transaction. A GncTransaction object on the
other hand will be converted, along with its attendant splits, and then deleted
by its parent.
Since at any one time an object will only be processing either a subobject or a
data element, a single object variable, m_state, is used to determine the actual
type. In effect, it acts as the current index into either the subElement or
dataElement list. As an object variable, it will be saved on the stack across
subobject processing.
Exceptions and Problems
Fatal exceptions are processed via the standard MyMoneyException method.
Due to differences in implementation between GnuCash and KMM, it is not always
possible to provide an absolutely correct conversion. When such a problem
situation is recognized, a message, along with any relevant variable data, is
passed to the main class, and used to produce a report when processing
terminates. The GncMessages and GncMessageArg classes implement this.
Anonymizer
When debugging problems, it is often useful to have a trace of what is happening
within the module. However, in view of the sensitive nature of personal finance
data, most users will be reluctant to provide this. Accordingly, an anonymize
(hide()) function is provided to handle data strings. These may either be passed
through asis (non-personal data), blanked out (non-critical but possibly personal
data), replaced with a generated version (required, but possibly personal), or
randomized (monetary amounts). The action for each data item is determined in
the object's constructor function along with the creation of the data element
list.
This module will later be used as the basis of a file anonymizer, which will
enable users to safely provide us with a copy of their GnuCash files, and will
allow us to test the structure, if not the data content, of the file.

Investments

you must select one of the following options.
0 - create a separate investment account for each stock with the same name as the stock
1 - create a single investment account to hold all stocks - you will be asked for a name
2 - create multiple investment accounts - you will be asked for a name for each stock
