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
