Some nice helper functions for strict file writing, appending and reading. All read-functions are strict, in the sense that the whole file is read at once and the content is stored into memory. So you won't have any semi-closed handles which might bring you in trouble from time to time. The files are immedialty closed after the reading. This Module can handle four filetypes: XML-Files, List-Files, Binary-Files and Text-Files.
XML-Files: Normal textfiles, but the content is stored as a xml-representation. For the pickling, we use the HXT-Library (see http://www.fh-wedel.de/~si/HXmlToolbox/)
List-Files: Binary-Files, which store a list of data-objects. The main difference between Binary-Files and List-Files is, that you can append data to a List-File which will be automatically concatenated to the existing list. If you try this with a normal Binary-File, you'll get only the original list and the appended data will be lost.
Binary-Files: Normal binary files, for the encoding and decoding, we use the Haskell binary-package.
Text-Files: Normal text files.

Loads an XML-File and parses the content to a specified datatype.
Converts a dataset to XML and saves the XML-string into a file.
lists in binary files
bytestring file handling
Append data to a binary file, this doesn't mean, that the contents are really concatenated when you read the file.
Reads the data from a binary file as a bytestring.
