Question

I am trying to convert xml file into csv file. How to read and parse xml file and convert into csv? Is there any package to convert xml into csv.

<services>
    <service>
        <ServiceID>1</ServiceID>
        <ServiceName>eVoting Booth</ServiceName>
    </service>
    <service>
        <ServiceID>2</ServiceID>

    </service>
        <service>
        <ServiceID>4</ServiceID>
        <ServiceName>Customer Service</ServiceName>
    </service>
    <service>
        <ServiceID>5</ServiceID>
        <ServiceName>Migrant Service</ServiceName>
    </service>
</services>

I want result as

ServiceID | ServiceName

2         | Justice of the Peace

Answer 1

something like this could work:

from lxml import etree
import pandas as pd

tree = etree.parse("input.xml")

df = pd.DataFrame({
    "ServiceID" : tree.xpath('/services/service/ServiceID/text()'),
    "ServiceName" : tree.xpath('/services/service/ServiceName/text()')
})

df.to_csv("output.csv", sep="|", index = None)

this produces

ServiceID|ServiceName
1|eVoting Booth
2|Justice of the Peace
3|Library
4|Customer Service
5|Migrant Service
