Parsing XML in Python with Loop

Question

I am new to Python.

I have a piece of python I have written to take out a data element I need from an XML that I have. The problem is I do not know how to repeat it to get out all the elements that I need.

import xml.etree.ElementTree as ET
import lxml.etree


doc = lxml.etree.parse('datafiles.xml')
total_datasets = doc.xpath('count//driversUsed)')


tree = ET.parse('datafiles.xml')
root = tree.getroot()

alias = root[1]
dataset = alias[0]
current = dataset[0]

print(current.text)

So right now the current has the first value that I need but I need to do a loop where dataset = alias[1], dataset = alias[2] .... dataset = alias[total_datasets].

I've done a little bit of looping but I don't know how to do it where the variable is not just an integer but has the [] with the integer inside.

What do you mean take out a data element? Are you trying to create a new XML or extract data from existing XML? — Parfait

I think import lxml.etree can do work whatever you want... — Vipul Bhatt

Use for and you don't need total_datasets

for dataset in alias:
    current = dataset[0]
    print(current.text)

It is basic knowledge so better find some Python Tutorial.
