Как извлечь образец большого XML файла с python?

Question

У меня очень большое дерево XML, и я хотел бы взять его пример для проверки своего кода, который я хочу использовать для извлечения информации по всему дереву.

Данные выглядят так:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE population SYSTEM "http://www.matsim.org/files/dtd/population_v6.dtd">

<population desc="Switzerland Baseline">

    <attributes>
        <attribute name="coordinateReferenceSystem" class="java.lang.String" >Atlantis</attribute>
    </attributes>

Моя цель - извлечь каждый n-й person. Он не должен быть репрезентативным, то есть его атрибуты не имеют значения. Например, я хочу извлечь каждый 2-й person со всеми их attributes и plans (в моем файле я хотел бы взять, например, каждую 1000-ую). Решение должно выглядеть следующим образом:
