    I am using xmltodict.

    This is how I have accessed and loaded my file.

    import xmltodict
    document = open("/home/sayth/Scripts/va_benefits/20140508GOSF0.xml", "r")
    read_doc = document.read()
    xml_doc = xmltodict.parse(read_doc)

    The start of the file I am trying to get data out of is.

    <meeting id="35483" barriertrial="0" venue="Gosford" date="2014-05-08T00:00:00" gearchanges="-1" stewardsreport="-1" gearlist="-1" racebook="0" postracestewards="0" meetingtype="TAB" rail="True" weather="Fine " trackcondition="Dead " nomsdeadline="2014-05-02T11:00:00" weightsdeadline="2014-05-05T16:00:00" acceptdeadline="2014-05-06T09:00:00" jockeydeadline="2014-05-06T12:00:00">
    <club abbrevname="Gosford Race Club" code="49" associationclass="2"website="http://" />
    <race id="185273" number="1" nomnumber="7" division="0" name="GOSFORD ROTARY MAIDEN HANDICAP" mediumname="MDN" shortname="MDN" stage="Acceptances" distance="1600" minweight="55" raisedweight="0" class="MDN " age="~ " grade="0" weightcondition="HCP " trophy="0" owner="0" trainer="0" jockey="0" strapper="0" totalprize="22000" first="12250" second="4250" third="2100" fourth="1000" fifth="525" time="2014-05-08T12:30:00" bonustype="BX02 " nomsfee="0" acceptfee="0" trackcondition=" " timingmethod=" " fastesttime=" " sectionaltime=" " formavailable="0" racebookprize="Of $22000. First $12250, second $4250, third $2100, fourth $1000, fifth $525, sixth $375, seventh $375, eighth $375, ninth $375, tenth $375">
    <condition line="1">

    So thought I had it figured. Can access the elements of meeting and the elements of club such as by doing this.

    In [5]: xml_doc['meeting']['club']['@abbrevname']
    Out[5]: u'Gosford Race Club'

    However whenever I try and access race in the same manner I get errors.

    In [11]: xml_doc['meeting']['club']['race']['@id']
    ---------------------------------------------------------------------------
    KeyError Traceback (most recent call last)
    <ipython-input-11-cce362d7e6fc> in <module>()
    ----> 1 xml_doc['meeting']['club']['race']['@id']

    KeyError: 'race'

    In [12]: xml_doc['meeting']['race']['@id']
    ---------------------------------------------------------------------------
    TypeError Traceback (most recent call last)
    <ipython-input-12-c304e2b8f9be> in <module>()
    ----> 1 xml_doc['meeting']['race']['@id']

    TypeError: list indices must be integers, not str

    why is accessing race @id any different to the access of club @abbrevname and how do I get it for race?

    Thanks

    If I were to guess: there are multiple races per meeting, xmltodict puts
    them into a list under the "race" key, and you have to pick one:
    .... <meeting>
    .... <race id="first race">...</race>
    .... <race id="second race">...</race>
    'second race'

    So

    xml_doc['meeting']['race'][0]['@id']

    or

    for race in xml_doc["meeting"]["race"]:
    print(race["@id"])

    might work for you.
