Namespaces
XML namespaces are entry point for tags <> classes linking. It defines in the same time a group for tags, a global object to put the classes into to be organised and an url entry point to load files from.
There are 2 type of namespaces, external and local. It depends of the notation, url or class path (package):
- jx="http://ns.devingfx.com/jxml/2015"
- js="data.*"
- local="*"
The local notation is a point syntax tree, that is replaced by folder tree when resolving: ./data/ the asterisk (*) means all package in the namespace, it's FLex legacy and ignored here. The current folder (and window global object) can be assigned to a namespace, here named "local" with just an asterisk.
If this namespace entry point has some grouped code to load, like compiled package, or namespace globals, Jilex try to load a package.js file at this urls:
- http://ns.devingfx.com/jxml/2015/package.js
- ./data/package.js
- ./themes/package.js
- ./package.js
Either the package.js defines all the component classes of the namespace's component, either Jilex will try to load a component later if don't exist yet based on node's namespace and localName.
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:jx="http://ns.devingfx.com/jxml/2015"
xmlns:js="data.*"
xmlns:theme="themes.*"
xmlns:local="*">
<theme:Chooser>
<theme:Dark/>
<theme:Chooser>
<jx:Element/>
<jx:Editor/>
<local:MyComp text="Coucou"/>
<local:MySuperComp/>
<local:Button>Coucou</local:Button>
<js:Array id="myData">
<js:String>Coucou</js:String>
<js:String>Monde</js:String>
<js:Number>42</js:Number>
<js:Boolean>false</js:Boolean>
<js:Object>
<js:String key="title">Coucou</js:String>
<js:Number key="count">42</js:Number>
<js:Boolean key="doAnything">false</js:Boolean>
</js:Object>
<js:json>{"go": { "ahead": "with", "your": "plain", "json": true} }</js:json>
<js:RegExp modifier="g">(.*?)@(.*?).(.*?)</js:RegExp>
</js:Array>
<js:XML source="./datas/catalog.xml"></js:XML>
default namespace :
<Editor xmlns="http://ns.devingfx.com/jxml/2015">
<Button label="Editor"/>
<jx:TextInput value="monde"/>
</Editor>
</html>In the above exemple, 5 xmlns attribute are present, so are the 5 corresponding namespaces.
| attribute | entry point | objects |
|---|---|---|
| xmlns="http://www.w3.org/1999/xhtml" | dont load | html.* |
| xmlns:jx="http://ns.devingfx.com/jxml/2015" | http://ns.devingfx.com/jxml/2015/* | jx.* |
| xmlns:js="data.*" | ./data/* | data.* |
| xmlns:theme="themes.*" | ./themes/* | theme.* |
| xmlns:local="*" | ./* | window.* |
all jx components are included in package.js, so
jx.Element, jx.Editor, jx.Button, jx.TextInputare used for
<jx:Element/> <jx:Editor/> <Editor xmlns="http://ns.devingfx.com/jxml/2015"> <Button/> <jx:TextInput/>directly, and Jilex will try to load the rest:
- ./themes/Chooser.xhtml
- ./MyComp.xhtml > not found
- ./MyComp.js
- ./MySuperComp.xhtml
- ./Button.js
- ./js/package.js > set component list with urls,
- ./js/Array.js
- ./js/String.js
- ./js/Number.js
- ./js/Boolean.js
- ./js/Object.js
- ./js/json.js
- ./js/RegExp.js
- ./js/XML.js
With HTML5 documents you can't use self-closing tag you must close your tags
<jx:Button></jx:Button>. And remember the browser will lowercase your tagnames so you have to be carefull of classes naming, asns.Button and ns.ButtOnare correctly 2 javascript classes but the corresponding tags<ns:Button> and <ns:ButtOn>are the same lowercased html tag when parsed ...
