[jira] Created: (TAPESTRY-2541) A component should be able to
access its own body
A component should be able to access its own body
-------------------------------------------------
Key: TAPESTRY-2541
URL: https://issues.apache.org/jira/browse/TAPESTRY-2541
Project: Tapestry
Issue Type: New Feature
Components: tapestry-core
Affects Versions: 5.0.13
Reporter: Martin Papy
It would be useful if I want to write a component that needs to manipulate its body... A trivial example would be a "stripwhitespace" component :
<t:stripwhitespace>
My string with too
many white spaces
</ t:stripwhitespace>
In that case I would like to access the <t:body /> string to remove some spaces...

Martin Papy commented on TAPESTRY-2541:
---------------------------------------
HLS said this :
Tapestry renders content as a lightweight DOM, not a character stream (as Tapestry 4 did). The approach I'd take is two fold: I would start a new element inside beginRender() and store the Element object inside a component field. Inside afterRender(), I would visit the context of the element, looking for Text nodes that I could change.
What's missing is that the API for Element, Text and Node allows for additions to a Node (this is how Tapestry adds <link> elements for CSS and <script> elements for JavaScript to a rendered page), but there's very little support for otherwise modifying the DOM structure. New API to remove, replace and reparent DOM nodes would help with what you're trying to accomplish. Again, more API is needed, but that kind of change is driven by an actual need, either by the framework, or by people creating JIRA issues.
