anchor

It is equivalent in functionality to the anchor attribute but contrarily to the latter, it inserts an anchor tag “in place” :

<tr do='each'>
  <td><r:anchor/><r:zazen attr='text'/></td>
</tr>

Will produce something like this:

<tr>
  <td><a class='anchor' name='node22'></a>...zazen content</td>
</tr>

You can also use RubyLess evaluated strings to build the anchor name:

<r:anchor anchor='foo#{id}'/>

If you intend to use textual values that could contain non-ascii characters, you should encode them (see String) :

<r:anchor anchor='foo#{title.urlencode}'/>
