from xml.etree.ElementTree import ElementTree, Element

def read_xml(in_path):
'''读取并解析xml文件'''
tree = ElementTree()
tree.parse(in_path)
return tree

def write_xml(tree, out_path):
'''保存xml文件'''
tree.write(out_path, encoding="utf-8", xml_declaration=False)

if __name__ == "__main__":
# 读取xml文件
tree = read_xml("femalasadzzl0.xml")

# 找到父节点
root = tree.getroot()
# 属性更改
for child in root.getchildren():
if child.tag == 'object':
child[2].text = '0'
child[3].text = '0'

write_xml(tree, 'femalasadzzl0.xml')

进一步修改,实现当前目录下xml批量更新
