Single element array

[numjcp]

Hello,
great job with this python module !!

However, i came across a simple problem.
Say i wish to convert the following xml to json along yahoo convention

i get
{"commandes": {"commande": [{}, {}]}}
which is ok for me.

But if i convert the same xml with only one object

i get
{"commandes": {"commande": {}}}
which is Good but not the behavior I expect. I'd like to get the single element within an array as if several objects where present. That is to say :
{"commandes": {"commande": [{}]}}

Thanks

<commandes><commande/><commande/></commandes>
and
<commandes><commande/></commandes>

are the source xml's

Here's a quick fix at first glance.

(How) would you like to integrate this behaviour ?

def data(self, root):
        '''Convert etree.Element into a dictionary'''
        value = self.dict()
        children = [node for node in root if isinstance(node.tag, basestring)]
        for attr, attrval in root.attrib.items():
            attr = attr if self.attr_prefix is None else self.attr_prefix + attr
            value[attr] = self._fromstring(attrval)
        if root.text and self.text_content is not None:
            text = root.text.strip()
            if text:
                if self.simple_text and len(children) == len(root.attrib) == 0:
                    value = self._fromstring(text)
                else:
                    value[self.text_content] = self._fromstring(text)
        count = Counter(child.tag for child in children)
        for child in children:
            #if count[child.tag] == 1:
            #    value.update(self.data(child))
            #else:
            result = value.setdefault(child.tag, self.list())
            result += self.data(child).values()
        return self.dict([(root.tag, value)])

This is exactly the same issue i'm facing.

I think, this problem is more related to the source file or the need for a xsd where the expected elements are described

[javadev]

{
   "commandes": {
      "commande": [
         {
         },
         {
         }
      ]
   }
} 

may be converted to xml

<?xml version="1.0" encoding="UTF-8"?>
<commandes>
  <commande></commande>
  <commande></commande>
</commandes>

I'm having the same issue with the Parker Convention -> No problem here, as how I found out, Parker is specified that way. There is though another convention 'Spark' that is similar to Parker, but treats single entries as lists.

Perhaps someone could also provide 'Spark' Convention as an extension to xmljson?
