% Function ParseSEMAINEAnnotations is intended to demonstrate example usage
% of SEMAINE Action Unit annotations made with ELAN annotation toolbox.
% This function loads the XML structure from an ELAN annotation file with
% ".eaf" extension, parses it and returns a numerical matrix called
% "activations" of size NUMBER OF FRAMES X NUMBER OF ACTION UNITS. The
% matrix holds binary activation status for each frame / AU combination.
% The matrix also has a row header showing which AU corresponds to which
% row as well as a column header displaying original frame indexes.
% The function takes 1 compulsory and 2 optional arguments:
% - "filepath" (compulsory) - complete path to an annotation file to parse.
% For example, "/matlab/annotation.eaf" or "C:\matlab\annotation.eaf" on
% Windows.
% - "startFrame" (optional) - ignore all annotations before "startFrame".
% Default is 1.
% - "endFrame" (optional) - ignore all annotations after "endFrame".
% Default is the last frame of a video.
% The function requires XML IO Toolbox
% (http://www.mathworks.com/matlabcentral/fileexchange/12907-xml-io-tools)
% to run properly (supplied).

function [tree, RootName, DOMnode] = xml_read(xmlfile, Pref)
%XML_READ reads xml files and converts them into Matlab's struct tree.
%
% DESCRIPTION
% tree = xml_read(xmlfile) reads 'xmlfile' into data structure 'tree'
%
% tree = xml_read(xmlfile, Pref) reads 'xmlfile' into data structure 'tree'
% according to your preferences
%
% [tree, RootName, DOMnode] = xml_read(xmlfile) get additional information
% about XML file
%
% INPUT:
% xmlfile URL or filename of xml file to read
% Pref Preferences:
% Pref.ItemName - default 'item' - name of a special tag used to itemize
% cell arrays
% Pref.ReadAttr - default true - allow reading attributes
% Pref.ReadSpec - default true - allow reading special nodes
% Pref.Str2Num - default 'smart' - convert strings that look like numbers
% to numbers. Options: "always", "never", and "smart"
% Pref.KeepNS - default true - keep or strip namespace info
% Pref.NoCells - default true - force output to have no cell arrays
% Pref.Debug - default false - show mode specific error messages
% Pref.NumLevels- default infinity - how many recursive levels are
% allowed. Can be used to speed up the function by prunning the tree.
% Pref.RootOnly - default true - output variable 'tree' corresponds to
% xml file root element, otherwise it correspond to the whole file.
% Pref.CellItem - default 'true' - leave 'item' nodes in cell notation.
% OUTPUT:
% tree tree of structs and/or cell arrays corresponding to xml file
% RootName XML tag name used for root (top level) node.
% Optionally it can be a string cell array storing: Name of
% root node, document "Processing Instructions" data and
% document "comment" string
% DOMnode output of xmlread
%
% DETAILS:
% Function xml_read first calls MATLAB's xmlread function and than
% converts its output ('Document Object Model' tree of Java objects)
% to tree of MATLAB struct's. The output is in format of nested structs
% and cells. In the output data structure field names are based on
% XML tags, except in cases when tags produce illegal variable names.
%
% Several special xml node types result in special tags for fields of
% 'tree' nodes:
% - node.CONTENT - stores data section of the node if other fields are
% present. Usually data section is stored directly in 'node'.
% - node.ATTRIBUTE.name - stores node's attribute called 'name'.
% - node.COMMENT - stores node's comment section (string). For global
% comments see "RootName" output variable.
% - node.CDATA_SECTION - stores node's CDATA section (string).
% - node.PROCESSING_INSTRUCTIONS - stores "processing instruction" child
% node. For global "processing instructions" see "RootName" output variable.
% - other special node types like: document fragment nodes, document type
% nodes, entity nodes, notation nodes and processing instruction nodes
% will be treated like regular nodes
%
% EXAMPLES:
% MyTree=[];
% MyTree.MyNumber = 13;
% MyTree.MyString = 'Hello World';
% xml_write('test.xml', MyTree);
% [tree treeName] = xml_read ('test.xml');
% disp(treeName)
% gen_object_display()

% - Function inspired by Example 3 found in xmlread function.
% - Output data structures inspired by xml_toolbox structures.

for r = 1:nr
row = tr{r}.(Pref.TableName{2});
Table(r,1:length(row)) = row; %#ok<AGROW>
end
s = Table;
end
end
% --- Post-processing: convert 'struct of cell-arrays' to 'array of structs'
% Example: let say s has 3 fields s.a, s.b & s.c and each field is an
% cell-array with more than one cell-element and all 3 have the same length.
% Then change it to array of structs, each with single cell.
% This way element s.a{1} will be now accessed through s(1).a
vec = zeros(size(fields));
for i=1:nField, vec(i) = f.(fields{i}); end
if (numel(vec)>1 && vec(1)>1 && var(vec)==0) % convert from struct of
s = cell2struct(struct2cell(s), fields, 1); % arrays to array of struct
end % if anyone knows better way to do above conversion please let me know.
end
%% === Step 5: Process nodes with attributes =============================
if (node.hasAttributes && Pref.ReadAttr)
if (~isstruct(s)), % make into struct if is not already
ss.CONTENT=s;

s.ATTRIBUTE.(name) = value; % save again
end % end iAttr loop
end % done with attributes

if (iscell(x) && all(cellfun(@isstruct,x(:))) && numel(x)>1) % it's cell-array of structs
% numel(x)>1 check is to keep 1 cell-arrays created when Pref.CellItem=1
try % this operation fails sometimes
% example: change s(1).a{1}.b='jack'; s(1).a{2}.b='john'; to

% them to the same field structure by adding empty fields.
if (Pref.NoCells)

end
end % end catch
end
end
end
%% === Step 4: Post-process struct's created for nodes with children =====
% --- Post-processing: remove special 'item' tags ---------------------
% many xml writes (including xml_write) use a special keyword to mark
% arrays of nodes (see xml_write for examples). The code below converts
% s.item to s.CONTENT
ItemContent = false;
if (isfield(s,Pref.ItemName))
s.CONTENT = s.(Pref.ItemName);
s = rmfield(s,Pref.ItemName);
ItemContent = Pref.CellItem; % if CellItem than keep s.CONTENT as cells
end
% --- Post-processing: clean up CONTENT tags ---------------------
% if s.CONTENT is a cell-array with empty elements at the end than trim
% the length of this cell-array. Also if s.CONTENT is the only field than
% remove .CONTENT part and store it as s.
if (isfield(s,'CONTENT'))
if (iscell(s.CONTENT) && isvector(s.CONTENT))
x = s.CONTENT;
for i=numel(x):-1:1, if ~isempty(x{i}), break; end; end

%% Tutorial for xml_io_tools Package
% *By Jarek Tuszynski*
%
% Package xml_io_tools can read XML files into MATLAB struct and writes
% MATLAB data types to XML files with help of simple interface to
% MATLAB's xmlwrite and xmlread functions.
%
% Two function to simplify reading and writing XML files from MATLAB:
%
% * Function xml_read first calls MATLAB's xmlread function and than
% converts its output ('Document Object Model' tree of Java objects)
% to tree of MATLAB struct's. The output is in the format of nested
% structs and cells. In the output data structure field names are based on
% XML tags.
%
% * Function xml_write first convert input tree of MATLAB structs and cells
% and other types to tree of 'Document Object Model' nodes, and then writes
% resulting object to XML file using MATLAB's xmlwrite function. .
%
%% This package can:
% * Read most XML files, created inside and outside of MATLAB environment,
% and convert them to MATLAB data structures.
% * Write any MATLAB's struct tree to XML file

%% This package does not:
% * Guarantee to recover the same Matlab objects that were saved. If you
% need to be able to recover carbon copy of the structure that was saved
% than you will have to use one of the packages that uses special set of
% tags saved as xml attributes that help to guide the parsing of XML code.
% This package does not use those tags.
% * Guarantee to work with older versions of MATLAB. Functions do not work
% with versions of MATLAB prior to 7.1 (26-Jul-2005).
%
%% Change History
% * 2006-11-06 - original version
% * 2006-11-26 - corrected xml_write to handle writing Matlab's column
% arrays to xml files. Bug discovered and diagnosed by Kalyan Dutta.
% * 2006-11-28 - made changes to handle special node types like:
% COMMENTS and CDATA sections
% * 2007-03-12 - Writing CDATA sections still did not worked. The problem
% was diagnosed and fixed by Alberto Amaro. The fix involved rewriting
% xmlwrite to use Apache Xerces java files directly instead of MATLAB's
% XMLUtils java class.
% * 2007-06-21 - Fixed problem reported by Anna Kelbert in Reviews about
% not writing attributes of ROOT node. Also: added support for Processing
% Instructions, added support for global text nodes: Processing
% Instructions and comments, allowed writing tag names with special
% characters
% * 2007-07-20 - Added tutorial script file. Extended support for global
% text nodes. Added more Preference fields.
% * 2008-01-23 - Fixed problem reported by Anna Krewet of converting dates
% in format '2007-01-01' to numbers. Improved and added warning messages.
% Added detection of old Matlab versions incompatible with the library.
% Expanded documentation.
% * 2008-06-23 - Fixed problem with writing 1D array reported by Mark Neil.
% Extended xml_read's Pref.Num2Str to 3 settings (never, smart and always)
% for better control. Added parameter Pref.KeepNS for keeping or ignoring
% namespace data when reading. Fixed a bug related to writing 2D cell
% arrays brought up by Andrej's Mosat review.
% * 2008-09-11 - Resubmitting last upload - zip file is still old
% * 2009-02-26 - Small changes. More error handling. More robust in case of
% large binary objects. Added support for Base64 encoding/decoding of
% binary objects (using functions by Peter J. Acklam).
% * 2009-06-26 - changes to xml_read: added CellItem parameter to allow
% better control of reading files with 'item' notation (see comment by
% Shlomi); changed try-catch statements so xml_read would work for mablab
% versions prior to 7.5 (see Thomas Pilutti comment)
% * 2009-12-03 - added PreserveSpace parameter for contolling empty string
% handling as suggested by Sebastiaan. Fix suggested by Michael Murphy.
% Fixed number recognition code as suggested by Yuan Ren.
% * 2010-05-04 - implemented fixes suggested by Dylan Reynolds from Airbus.
% * 2010-07-28 - implemented support for 2D arrays of cells and structs
% suggested by Rodney Behn from MIT Lincoln Laboratory. Also attempted
% large scale cleanup of xml_write function
% * 2010-08-18 - minor extension to allow better handling of logical
% scalars and arrays and function handles suggested by Andreas Richter
% and others
% * 2010-09-20 - allow reading and writing of sparse matrices. Improve
% reading of 1D boolean arrays.
% * 2010-11-05 - Fix problem with empty cells reported by Richard Cotton;
% fixed issues with reading boolean arrays reported by Zohar Bar-Yehuda;
% Improved speed of base64 coding and decoding by switching to java based
% code.

%% Write XML files with special characters in TAG names
% The input to xml_write requires that all tags one wants in XML document
% have to be encoded as field names of MATLAB's struct's. Matlab has a lot
% of restrictions on variable names. This section is about XML tags with
% names not allowed as MATLAB variables, or more specifically with
% characters allowed as xml tag names but not allowed as MATLAB variable
% names. Characters like that can be replaced by their hexadecimal
% representation just as it is done by genvarname function. Alternative way
% of writing the first example is:
MyTree=[];
MyTree.('MyNumber') = 13; % same as MyTree.MyNumber = 13;
MyTree.MyString.CONTENT = 'Hello World';
MyTree.MyString.ATTRIBUTE.('Num') = 2; % same as MyTree.MyString.ATTRIBUTE.Num = 2;
xml_write('test.xml', MyTree);
type('test.xml')
%%
% *This approach fails for some characters like dash '-', colon ':', and
% international characters.*

MyTree.MyString.ATTRIBUTE.('Num_ö') = 2;
catch %#ok<CTCH>
err = lasterror; %#ok<LERR>
disp(err.message);
end
%%
% It can be overcome by replacing offending characters with their
% hexadecimal representation. That can be done manually or with use of
% genvarname function. Note that MATLAB 'type' function does not show
% correctly 'ö' letter in xml file, but opening the file in editor shows
% that it is correct.
MyTree=[];
MyTree.(genvarname('My-Number')) = 13;
MyTree.MyString.CONTENT = 'Hello World';
MyTree.MyString.ATTRIBUTE.Num_0xF6 = 2;
gen_object_display(MyTree);

function DOMnode = xml_write(filename, tree, RootName, Pref)
%XML_WRITE Writes Matlab data structures to XML file
%
% DESCRIPTION
% xml_write( filename, tree) Converts Matlab data structure 'tree' containing
% cells, structs, numbers and strings to Document Object Model (DOM) node
% tree, then saves it to XML file 'filename' using Matlab's xmlwrite
% function. Optionally one can also use alternative version of xmlwrite
% function which directly calls JAVA functions for XML writing without
% MATLAB middleware. This function is provided as a patch to existing
% bugs in xmlwrite (in R2006b).
%
% xml_write(filename, tree, RootName, Pref) allows you to specify
% additional preferences about file format
%
% DOMnode = xml_write([], tree) same as above except that DOM node is
% not saved to the file but returned.
%
% INPUT
% filename file name
% tree Matlab structure tree to store in xml file.
% RootName String with XML tag name used for root (top level) node
% Optionally it can be a string cell array storing: Name of
% root node, document "Processing Instructions" data and
% document "comment" string
% Pref Other preferences:
% Pref.ItemName - default 'item' - name of a special tag used to
% itemize cell or struct arrays
% Pref.XmlEngine - let you choose the XML engine. Currently default is
% 'Xerces', which is using directly the apache xerces java file.
% Other option is 'Matlab' which uses MATLAB's xmlwrite and its
% XMLUtils java file. Both options create identical results except in
% case of CDATA sections where xmlwrite fails.
% Pref.CellItem - default 'true' - allow cell arrays to use 'item'
% notation. See below.
% Pref.RootOnly - default true - output variable 'tree' corresponds to
% xml file root element, otherwise it correspond to the whole file.
% Pref.StructItem - default 'true' - allow arrays of structs to use
% 'item' notation. For example "Pref.StructItem = true" gives:
% <a>
% <b>
% <item> ... <\item>
% <item> ... <\item>
% <\b>
% <\a>
% while "Pref.StructItem = false" gives:
% <a>
% <b> ... <\b>
% <b> ... <\b>
% <\a>
%
%
% Several special xml node types can be created if special tags are used
% for field names of 'tree' nodes:
% - node.CONTENT - stores data section of the node if other fields
% (usually ATTRIBUTE are present. Usually data section is stored
% directly in 'node'.
% - node.ATTRIBUTE.name - stores node's attribute called 'name'.
% - node.COMMENT - create comment child node from the string. For global
% comments see "RootName" input variable.
% - node.PROCESSING_INSTRUCTIONS - create "processing instruction" child
% node from the string. For global "processing instructions" see
% "RootName" input variable.
% - node.CDATA_SECTION - stores node's CDATA section (string). Only works
% if Pref.XmlEngine='Xerces'. For more info, see comments of F_xmlwrite.
% - other special node types like: document fragment nodes, document type
% nodes, entity nodes and notation nodes are not being handled by
% 'xml_write' at the moment.
%
% OUTPUT
% DOMnode Document Object Model (DOM) node tree in the format
% required as input to xmlwrite. (optional)
%
% EXAMPLES:
% MyTree=[];
% MyTree.MyNumber = 13;
% MyTree.MyString = 'Hello World';
% xml_write('test.xml', MyTree);
% type('test.xml')

function varargout=xmlwrite_xerces(varargin)
%XMLWRITE_XERCES Serialize an XML Document Object Model node using Xerces parser.
% xmlwrite_xerces(FILENAME,DOMNODE) serializes the DOMNODE to file FILENAME.
%
% The function xmlwrite_xerces is very similar the Matlab function xmlwrite
% but works directly with the XERCES java classes (written by Apache XML
% Project) instead of the XMLUtils class created by Mathworks. Xerces files
% are provided in standard MATLAB instalation and live in root\java\jarext
% directory.
%
% Written by A.Amaro (02-22-2007) and generously donated to xml_io_tools.
% This function is needed as a work-around for a bug in XMLUtils library
% which can not write CDATA SECTION nodes correctly. Also Xerces and
% XMLUtils libraries handle namespaces differently.
%
% Examples:
% % See xmlwrite examples this function have almost identical behavior.
%
% Advanced use:
% FILENAME can also be a URN, java.io.OutputStream or java.io.Writer object
% SOURCE can also be a SAX InputSource, JAXP Source, InputStream, or
% Reader object

% SERIALIZATION OF THE DOM DOCUMENT USING XERCES CLASSES DIRECTLY
% 1) create the output format according to the document definitions
% and type
objOutputFormat = org.apache.xml.serialize.OutputFormat(source);
set(objOutputFormat,'Indenting','on');
% 2) create the output stream. In this case: an XML file
objFile = java.io.File(result);
objOutputStream = java.io.FileOutputStream(objFile);
% 3) Create the Xerces Serializer object
objSerializer= org.apache.xml.serialize.XMLSerializer(objOutputStream,objOutputFormat);
% 4) Serialize to the XML files

% 5) IMPORTANT! Delete the objects to liberate the XML file created
