xml -> dict: lxml faq solution inadequate

[Johann Spies]

In the lxml-faq I read:

How can I map an XML tree into a dict of dicts?

I'm glad you asked.

def recursive_dict(element):
     return element.tag, \
            dict(map(recursive_dict, element)) or element.text

However this does not work where you have xml-elements where there are
more than one child on the same level.  For example:

<keywords count="4">
<keyword>Bayesian nonparametric statistics</keyword>
<keyword>Frailty modeling</keyword>
<keyword>Poly urn sampling</keyword>
<keyword>Proportional hazards model</keyword>
</keywords>

results in

>>> alys[100]['item']['keywords']
{'keyword': 'Proportional hazards model'}

 How do I get it to give me the following result?

{'keywords': [
{'keyword': 'Bayesian nonparametric statistics'},
{'keyword': 'Frailty modeling'},
{'keyword': 'Poly urn sampling'},
{'keyword': 'Proportional hazards model'}
]}
