解析使用xml.etree.ElementTree 模块，生成使用xml.dom.minidom模块，  ElementTree比dom快，dom生成简单且会自动格式化。

        111
                       
       
        111

解析为dict：

{0: {
   'retry': '111', 'auth_type': '111', 'portal_version': '1', 'timeout': '111', 'basprovider': '0'}, 1: {
   'retry': '3', 'auth_type': '0', 'portal_version': '1', 'timeout': '5000', 'basprovider': '0'}}

将上述字典再还原xml 执行代码：

# coding = 'utf-8'import timeimport xml.etree.ElementTree as ETimport xml.dom.minidom as minidomstart = time.clock()  # 记录处理开始时间；与最后一行一起使用，来判断输出运行时间。def read_xml(in_path):    """读取并解析xml文件       in_path: xml路径       return: tree"""    tree = ET.parse(in_path)    return treedef creat_dict(root):    """xml生成为dict：，    将tree中个节点添加到list中，将list转换为字典dict_init    叠加生成多层字典dict_new"""    dict_new = {}    for key, valu in enumerate(root):        dict_init = {}        list_init = []        for item in valu:            list_init.append([item.tag, item.text])            for lists in list_init:                dict_init[lists[0]] = lists[1]        dict_new[key] = dict_init    return dict_newdef dict_to_xml(input_dict, root_tag, node_tag):    """ 定义根节点root_tag，定义第二层节点node_tag    第三层中将字典中键值对对应参数名和值       return: xml的tree结构 """    root_name = ET.Element(root_tag)    for (k, v) in input_dict.items():        node_name = ET.SubElement(root_name, node_tag)        for key, val in v.items():            key = ET.SubElement(node_name, key)            key.text = val    return root_namedef out_xml(root):    """格式化root转换为xml文件"""    rough_string = ET.tostring(root, 'utf-8')    reared_content = minidom.parseString(rough_string)    with open(out_file, 'w+') as fs:        reared_content.writexml(fs, addindent=" ", newl="\n", encoding="utf-8")    return Trueif __name__ == '__main__':    in_files = r"D:\baspool_read.xml"    out_file = r"D:\baspool_out.xml"    tree = read_xml(in_files)    node_new = creat_dict(tree.getroot())  # 将xml转换为dict    root = dict_to_xml(node_new, "baspools", "bas")  # 将dict转换为xml    out_xml(root)     # 输出xml到out_filesend = time.clock()print("read: %f s" % (end - start))

 

 

解决 字典无顺序导致生成的xml文件参数位置不固定，对dict_to_xml()函数进行修正：

def dict_to_xml(input_dict,root_tag,node_tag):    """ 定义根节点root_tag，定义第二层节点node_tag    第三层中将字典中键值对对应参数名和值       return: xml的tree结构 """    root_name = ET.Element(root_tag)    for (k, v) in input_dict.items():        node_name = ET.SubElement(root_name, node_tag)        for (key, val) in sorted(v.items(), key=lambda e:e[0], reverse=True):            key = ET.SubElement(node_name, key)            key.text = val    return root_name
