Template Attribute Language
The Template Attribute Language (TAL) is an attribute language used to create dynamic templates. It allows elements of a document to be replaced, repeated, or omitted.
The statements of TAL are XML/HTML attributes from the TAL namespace.
Example
A webdesigner's template like
<div class="article"> <h1>Article Title</h1> <div class="author">Author's name</div> ...
can be modified by a developer to fetch appropriate content
<div class="article"> <h1 tal:content="currentObject.label">Article Title</h1> <div class="author" tal:content="currentObject.authorsSet[0].label"> Author's name</div> ...
and remains understandable by the webdesigner, and editable in graphical HTML editors.
