Use an xml parser to fetch the data from the xml file and use a template 
engine to generate the lua code.

for instance, using bs4 (beautifulsoup) for xml and jinja2 for the 
template engine:

import bs4
import jinja2

xml = """<cities>
      <city>
               <name>BuenosAires</name>
               <temperature>30</temperature>
       </city>
<city>
       <name>Seatle</name>
       <temperature>25</temperature>
</city>
</cities>"""

lua_template = """
cities_temps ={
{%- for city, temp in cities.iteritems() %}
["{{city}}"] = {{temp}},
{%- endfor %}
}"""

xmlp = bs4.BeautifulSoup(xml, 'xml')
# from xml to python dictionary
data = {city.find('name').string:city.find('temperature').string for 
city in xmlp.findAll('city')}
# from python dictionary to lua
print jinja2.Template(lua_template).render(cities=data)


will yield (python 2.7):

cities_temps ={
["BuenosAires"] = 30,
["Seatle"] = 25,
}
