tapestry.html

  This package currently only defines one DOM String related function. 

  The source for <<<tapestry.html>>> can be found {{{http://svn.apache.org/viewvc/tapestry/tapestry4/trunk/tapestry-framework/src/js/tapestry/html.js?view=markup}here}}. 

* tapestry.html.getContentAsString(node)

  Used primarily in {{{core.html}tapestry.bind}} to convert incoming XML document node content into a 
  javascript String that will be compatible with DomNode.innerHTML calls. The semantics of using innerHTML
  are fairly quircky from browser to browser <(if you want to maintain stylesheet rules/etc)>, so this function
  will determine your browser type and act accordingly. It should universally be able to produce a String compatible
  with innerHTML statements from almost any source, even existing HTML DOM nodes that aren't part of an IO
  XML document return.

  Parameter            |    Type	   |  Required  | Default  | 		Description
*----------------------*---------------*------------*----------*----------------------------------------------+
  node 				   | DOMNode/HtmlDOMNode    |  yes       |          | The XML or HTML DOM node to parse html textual fragment contents from.
*----------------------*---------------*------------*----------*----------------------------------------------+

** Example usage

  If you wanted to take an IO return chunk of xml that looked like this:
  
+----------------------------
<?xml version="1.0"?>
<ajax-response>
<response id="chunk1" type="element">
This is some example html content.

<p>
As you can see, any valid html element can be embedded in the response.
</p>
</response>
</ajax-response>
+----------------------------

  and place it's content into an existing HTML dom node you might do something like this:
  
+-----------------------------------------------------------
dojo.require("tapestry.html"); // ensures tapestry.html package is loaded

var xmlData=functionFoo();
var domNode = xmlData.getElementById("chunk1");

dojo.byId("myHtmlNode").innerHTML=tapestry.html.getContentAsString(domNode);
+-----------------------------------------------------------
