Simple CSV to XML Conversion - Python

Question

I am looking for a way to automate the conversion of CSV to XML.

Here is an example of a CSV file, containing a list of movies:

Here is the file in

Answer 1

A possible solution is to first load the csv into Pandas and then convert it row by row into XML, as so:

import pandas as pd
df = pd.read_csv('untitled.txt', sep='|')

With the sample data (assuming separator and so on) loaded as:

          Title                   Type Format  Year Rating  Stars  \
0  Enemy Behind           War,Thriller    DVD  2003     PG     10   
1  Transformers  Anime,Science Fiction    DVD  1989      R      9   

             Description  
0          Talk about...  
1  A Schientific fiction  

And then converting to xml with a custom function:

def convert_row(row):
    return """<movietitle="%s">
    <type>%s</type>
    <format>%s</format>
    <year>%s</year>
    <rating>%s</rating>
    <stars>%s</stars>
    <description>%s</description>
</movie>""" % (
    row.Title, row.Type, row.Format, row.Year, row.Rating, row.Stars, row.Description)

print '\n'.join(df.apply(convert_row, axis=1))

This way you get a string containing the xml:

<movietitle="Enemy Behind">
    <type>War,Thriller</type>
    <format>DVD</format>
    <year>2003</year>
    <rating>PG</rating>
    <stars>10</stars>
    <description>Talk about...</description>
</movie>
<movietitle="Transformers">
    <type>Anime,Science Fiction</type>
    <format>DVD</format>
    <year>1989</year>
    <rating>R</rating>
    <stars>9</stars>
    <description>A Schientific fiction</description>
</movie>

that you can dump in to a file or whatever.

Inspired by this great answer.

Edit: Using the loading method you posted (or a version that actually loads the data to a variable):

import csv              
f = open('movies2.csv')
csv_f = csv.reader(f)   
data = []

for row in csv_f: 
   data.append(row)
f.close()

print data[1:]

We get:

[['Enemy Behind', 'War', 'Thriller', 'DVD', '2003', 'PG', '10', 'Talk about...'], ['Transformers', 'Anime', 'Science Fiction', 'DVD', '1989', 'R', '9', 'A Schientific fiction']]

And we can convert to XML with minor modifications:

def convert_row(row):
    return """<movietitle="%s">
    <type>%s</type>
    <format>%s</format>
    <year>%s</year>
    <rating>%s</rating>
    <stars>%s</stars>
    <description>%s</description>
</movie>""" % (row[0], row[1], row[2], row[3], row[4], row[5], row[6])

print '\n'.join([convert_row(row) for row in data[1:]])

Getting identical results:

<movietitle="Enemy Behind">
    <type>War</type>
    <format>Thriller</format>
    <year>DVD</year>
    <rating>2003</rating>
    <stars>PG</stars>
    <description>10</description>
</movie>
<movietitle="Transformers">
    <type>Anime</type>
    <format>Science Fiction</format>
    <year>DVD</year>
    <rating>1989</rating>
    <stars>R</stars>
    <description>9</description>
</movie>
