/**
|
||||
* Implementation of the XForms \<repeat\> control.
|
||||
* @see http://www.w3.org/TR/xforms/slice9.html#id2632123
|
||||
*
|
||||
* On Refresh(), nsXFormsRepeatElement, does the following for each node in
|
||||
* the nodeset the \<repeat\> tag is bound to:
|
||||
*
|
||||
* 1) Creates a new \<repeatitem\> (nsXFormsRepeatItemElement)
|
||||
*
|
||||
* 2) Clones all its children (that is children of its nsIXTFXMLVisualWrapper)
|
||||
* and appends them as children to the nsXFormsRepeatItemElement
|
||||
*
|
||||
* 3) Sets the context node and size for the nsXFormsRepeatItemElement, so
|
||||
* that children can retrieve this through nsIXFormsContextControl.
|
||||
*
|
||||
* 4) Inserts the nsXFormsRepeatItemElement into its visual content node
|
||||
* (mHTMLElement).
|
||||
*
|
||||
* For example, this instance data:
|
||||
* <pre>
|
||||
* <instance>
|
||||
* <data>
|
||||
* <n>val1</n>
|
||||
* <n>val2</n>
|
||||
* </data>
|
||||
* </instance>
|
||||
* </pre>
|
||||
*
|
||||
* and this repeat:
|
||||
* <pre>
|
||||
* <repeat nodeset="n">
|
||||
* Val: <output ref="."/>
|
||||
* </repeat>
|
||||
* </pre>
|
||||
*
|
||||
* will be expanded to:
|
||||
* <pre>
|
||||
* <repeat nodeset="n">
|
||||
* <repeatitem> (contextNode == "n[0]" and contextPosition == 1)
|
||||
* Val: <output ref="."/> (that is: 'val1')
|
||||
* </repeatitem>
|
||||
* <repeatitem> (contextNode == "n[1]" and contextPosition == 2)
|
||||
* Val: <output ref="."/> (that is: 'val2')
|
||||
* </repeatitem>
|
||||
* </repeat>
|
||||
* </pre>
|
||||
*
|
||||
* Besides being a practical way to implement \<repeat\>, it also means that it
|
||||
* is possible to CSS-style the individual "rows" in a \<repeat\>.
|
||||
*
|
||||
* @todo Support attribute based repeats (XXX), as in:
|
||||
* \<html:table xforms:repeat-nodeset="..."\>
