将lxml etree拆分为多个etree对象

Question

是否有按索引将子元素的etree对象集拆分为多个etree对象的函数？例如，如果我的根节点有400个子节点，每个子节点都有后代，那么我可以从文件的每一秒中获取4个etree对象吗？

from lxml import etree as ET

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

firstquarter = root.getchildren()   #function to get 0-100 of the child nodes
secondquarter = root.getchildren()  #function to get 101-200 of the child nodes
thirdquarter = root.getchildren()   #function to get 201-300 of the child nodes
fourthquarter = root.getchildren()  #function to get 301-400 of the child nodes

Answer 1

你应该可以简单地做一些类似的事情

firstquarter = root.getchildren()[0:100]

等。
