py:element directive

[Arc Riley <arcriley@…>]

Currently to generate elements from a list some hackery is needed, ie:

<?python from genshi.builder import tag ?>
<py:for each='field in fields'>
  ${getattr(tag,field)}
</py:for>

It would be cleaner if we could instead:

<py:for each='field in fields'>
  <py:element name="field"/>
</py:for>

py:attrs should be applied second such that:

<py:for each='field in fields'>
  <py:element name='field' py:attrs='fields[field]'/>
</py:for>

It would be useful if the element name could contain the namespace, ie:

fields = {'greek:alpha' : {'value' : 1, 'xmlns:greek' = 'xml:foo:greek'},
          'game:monsters' : {'hp' : 552, 'label' : 'Queen Banshee'}}

In XMPP there are many cases where it'd be useful for generated elements to be in different namespaces like this. A separate py:element namespace= attribute may also be useful in some situations but would increase complexity in the above examples.

I think that your working solution misses something in the likes of:

<?python from genshi.builder import tag ?>
<py:for each='field in fields'>
  ${getattr(tag,field)(**fields[field])}
</py:for>

nah, must have been out of my mind.. forget this.
