QUICK START:

- Open an xsd file.
- The xsd file and all its dependencies files are loaded in tab pages.
- Either:
	- Select a toplevel element in the toolbar (The first one is already selected).
	- Push the add button to put the element on the diagram
- Or double click in the right panel list.
- Then, on the diagram element, click on the + box or walk the tree with arrow keys.


COMMAND LINE USAGE: 

> XSDDiagram.exe [-o output.svg] [-os EXTENSION] [-r RootElement[@namespace]]* [-e N] [-d] [-z N] [-y] [-u USERNAME] [-p PASSWORD] [file.xsd or URL]

or on Windows use 'XSDDiagramConsole.exe' instead of 'XSDDiagram.exe' if you need the console:

> XSDDiagramConsole.exe [-o output.svg] [-os EXTENSION] [-r RootElement[@namespace]]* [-e N] [-d] [-z N] [-f PATH,NAME,TYPE,NAMESPACE,COMMENT,SEQ,LASTCHILD,XSDTYPE] [-a] [-y] [-u USERNAME] [-p PASSWORD] [file.xsd or URL]

Options:

-o FILE
	specifies the output image. '.png','.jpg', '.svg', '.txt', '.csv' ('.emf' on Windows) are allowed.
	If not present, the GUI is shown.
-os EXTENSION
	specifies the output image is streamed through the standard
	output. EXTENSION can be: png, jpg, svg, txt, csv.
	If not present, the GUI is shown.
-r ELEMENT
	specifies the root element of the tree.
	You can put several -r options = several root elements in the tree.
-e N
	specifies the expand level (from 0 to what you want).
	Be carefull, the result image can be huge.
-d
	Display the documentation.
-z N
	specifies the zoom percentage from 10% to 1000% (only for .png image).
	Work only with the '-o', '-os png' or '-os jpg' option.
-f PATH,NAME,TYPE,NAMESPACE,COMMENT,SEQ,LASTCHILD,XSDTYPE
	specifies the fields you want to output when rendering to a txt or csv file.
-a
	outputs the attributes in text mode only (.txt and .csv).
-y
	force huge image generation without user prompt.
-u USERNAME
	specifies a username to authenticate when a xsd dependency
	(import or include) is a secured url.
-p PASSWORD
	specifies a password to authenticate when a xsd dependency
	(import or include) is a secured url.
-no-gui
	prevents the graphical interface to be opened.


Example 1:
> XSDDiagramConsole.exe -o file.png -r TotoRoot -r TotoComplexType@http://mynamespace -e 3 -d -z 200 ./folder1/toto.xsd
	will generate a PNG image from a diagram with a root elements
	'TotoRoot' and 'TotoComplexType', and expanding the tree
	from the root until the 3rd level, with the documentation.

Example 2:
> XSDDiagram.exe ./folder1/toto.xsd
	will load the xsd file in the GUI window.

Example 3:
> XSDDiagram.exe -r TotoRoot -e 2 ./folder1/toto.xsd
	will load the xsd file in the GUI window with a root element
	'TotoRoot' and expanding the tree from the root until the 2nd level.

Example 4:
> XSDDiagramConsole.exe -os svg -r TotoRoot -e 3 ./folder1/toto.xsd
	will write a SVG image in the standard output from a diagram with a root element
	'TotoRoot' and expanding the tree from the root until the 3rd level.

Example 5:
> XSDDiagramConsole.exe -os txt -r TotoRoot -e 3 -f PATH,TYPE,COMMENT -a ./folder1/toto.xsd
	will write a textual representation in the standard output from a diagram with a root element
	'TotoRoot' and expanding the tree from the root until the 3rd level.


NOTES:

- With Mono on Linux, to prevent an exception with a missing assembly, please install the package "libmono-winforms2.0-cil"
(Prevent the error: Could not load file or assembly 'System.Windows.Forms').


TODO LIST:

- Add redefine (for external schema) and restrictions.
- Add an icon "Go to Diagram" on tool bar, to help working with lot of includes (Majo).
- Show/hide group elements in the settings (Mario M.).
- Font look blurry on Windows, add default font size in the settings (Mario M.).
- Add the infer XSD file in the command line.
- NoukNouk suggestions:
 + Add some display parameter like font type / size for tags / annotation... background color, vertical margin between tags...
 + Element window should be logically sorted - for example I think that name, type, minoccur, maxoccur,
   nillable should be on the top of this windows... and other unquoted data can remain in alphabetical order after these 5 first...
 + In element window again, type is showing the related namespace. It could be great to have the possibilty
   to hide it (or maybe duplicate type with a full type with namespace and short type W/O namespace)
 + "Pattern" tab addition with the Annotation / Element window in order to show tag restriction/pattern
   like this one: <xs:restriction base="xs:string"><xs:pattern value="[A-Z]{2,2}[0-9]{2,2}[a-zA-Z0-9]{1,30}" /></xs:restriction>
- BUG: Cascading substitution groups may appear weird.
- Add include a possibility to show the length of an element (Jörg S.)
- Add the attributes to the element in the diagram (suggested by bob)
- Tooltips above the diagram element with a summary (xpath/attributes/doc) (display 200ms after the mouse move -> avoid 100 %CPU)
	o The optional display of attributes inside the diagram
- Columns in the element/attributes tabs for restrictions (length/pattern/enumerations) 
- Multi-selection (i.e.: to remove several element at once)
- Save the current UI state (open file/diagram/zoom/...)
- XML sample (skeleton) generation (the ability to generate random test XML files complying with the open schema)
- Download .dtd dependency file
