Question

我想从我的xml文件中删除 CommentsCorrections 节点。我使用ElementTree XML API删除节点。我不知道为什么我的python代码不起作用，以下是python和xml的例子。

Python：

import xml.etree.ElementTree as ET 
tree = ET.parse("pubmed_result.xml")
root = tree.getroot()
for CommentsCorrections in root.findall('CommentsCorrections'):
     tree.remove(CommentsCorrections) 
tree.write("Scheduler.xml")

XML：

<CommentsCorrectionsList>
  <CommentsCorrections RefType="Cites">
    <RefSource>Clin Infect Dis. 2005 Nov 1;41(9):1254-60</RefSource>

Answer 1

您需要从root调用remove方法。

for CommentsCorrections in root.findall('CommentsCorrections'):
    root.remove(CommentsCorrections)
tree.write("Scheduler.xml")
