Question

我正在尝试解析大小超过1GB的XML文件，因此我使用 iterparse ，但我无法找到二级孩子。从下面的代码我能够得到elem的孩子而不是child1的孩子，即我无法进入child2循环

代码：

import xml.etree.cElementTree as ET
xmL = 'F:\\Reports\\Logs\\Result_TG1_V16.xml'

count = 0
flag =0
for event, elem in ET.iterparse(xmL,):
    if event == 'end':
        if elem.tag == 'TasksReportNode':
            count += 1

            for child1 in elem:
                print(child1.tag, child1.text)

                for child2 in child1:
                    print(child2.tag, child2.text)


        elem.clear() # discard the element

print count

Answer 1

这是我尝试过的：我使用了lxml而不是cElementtree

from lxml import etree
xmL = 'F:\\Reports\\Logs\\Result_TG1_V16.xml'
context = etree.iterparse(xmL,  events=("start", "end"),)
for event, element in context:
if element.tag == 'TasksReportNode':
    for child1 in element:
        for child2 in child1:
        if child2.get("RowCount") == "0":
            for child3 in child2:
               print(child3.tag, child3.text)
element.clear() # discard the element
del context

我可以获取所有子标签和数据。
