I think xml2dict cannot accomplish it, since I get the same key for
multiple values...
For example: mathml_prueba='''<mrow> <mfrac> <mrow> <mn>3</mn> </mrow>
<mrow> <mn>5</mn> </mrow> </mfrac> </mrow> '''
I get the following dict:
{'mrow': {'mfrac': {'mrow': [{'mn': '3'}, {'mn': '5'}]}}}
Notice the merged 'mrow' key...
Any suggestion for a xml lib to parse the expression?
