我正在尝试解析一个包含Directories_name，Files_name，permissions，creation_date_time，username，file_size，dir_size
列表的巨大XML文件xml的结构如下：
<parent_dir>
<file_1>
<sub-dir_1>
<file_2>
<sub-dir_2>
....
.....
实际文件如下所示：

现在，从这个XML，我想得到以下内容：
1）按以下格式解析几乎所有内容：
Parent_DIR：在这种情况下是C：
SQLite中的文件到DIR关系：驻留在C中的文件夹'Test_Software'包含26.avi，6.avi等。 对于每个文件夹，列出该文件夹中的文件，并以下列格式将该信息存储在DB的DIR_INFO表中： DIR名称为表的DIR_Name列，文件列表信息为File_Name列
2）获取所有文件的列表及其父路径。注意：查找名为“ future .pyc”的文件，其原始路径为：C：/Test_Software/Scripts/build/bdist.win-amd64/winexe/collect-2.7/ future < /strong>.pyc 我想在DB表File_info的File_name列中添加 future .pyc的文件名，然后在同一个DB表的file_full_path列的完整路径
所以，我能够使用以下代码获取所有File_info和Dir_info：
xml_out = etree.fromstring(single_bk)
file_info = xml_out.xpath('/browse/dir/file') # Files Path
dir_info = xml_out.xpath('/browse/dir') #Parent Path
dir_names = []
file_names = []
file_dates = []
dir_dates = []
dir_group = []
file_group = []
file_permissions = []
dir_permissions = []
file_size = []
dir_size = []
file_user = []
dir_user = []
for node in file_info:
file_names.append(node.xpath("@name")[0])
file_dates.append(node.xpath("@date")[0])
file_group.append(node.xpath("@group")[0])
file_permissions.append(node.xpath("@protection")[0])
file_size.append(node.xpath("@size")[0])
file_user.append(node.xpath("@user")[0])
for node in dir_info:
dir_names.append(node.xpath("@name")[0])
dir_dates.append(node.xpath("@date")[0])
dir_group.append(node.xpath("@group")[0])
dir_permissions.append(node.xpath("@protection")[0])
dir_size.append(node.xpath("@size")[0])
dir_user.append(node.xpath("@user")[0])
print file_names, file_dates, file_group, file_permissions, file_size, file_user
print '\n------------------------------------------------------------------\n'
print dir_names, dir_dates, dir_group, dir_permissions, dir_size, dir_user
print '\n------------------------------------------------------------------\n'
list_of_attributes = []
for node in dir_info:
attrs = []
for att in node.attrib:
#attrs.append(("@" + att, node.attrib[att]))
attrs.append((node.attrib[att]))
list_of_attributes.append(attrs)
print list_of_attributes
print '\n------------------------------------------------------------------\n'
print attrs
但是，它有以下限制：
1）我无法使用此方法映射整个XML，因为XML可以达到无穷大，可能需要将所有内容放在XML的无限循环中
2）我无法映射文件 - ＆gt; dir关系，因为使用此xml将文件映射到最外层的父项似乎太复杂了。例如：如果我正在阅读文件 future .pyc'，其原始路径为：C：/Test_Software/Scripts/build/bdist.win-amd64/winexe/collect-2.7/ 未来 .pyc，我想不出一个方法可以回到c：\ test_software并拥有完整的file_path
3）我想将sirite Dir_info表和file_info中的dir信息存储到file_info表中
这是我的sqlite表信息
数据库名称：abc.db 表格： a）DIR_INFO b）FILE_INFO
Columns of DIR_INFO Table
ID, DIR_DATE, DIR_NAME, DIR_FILE, DIR_SIZE , DIR_PERMISSIONS, DIR_USER
Columns of FILE_INFO Table
ID, FILE_DATE, FILE_NAME, FILE_PARENT_DIR, FILE_FULL_PATH, FILE_SIZE , FILE_PERMISSIONS, FILE_USER
如果你到达这里阅读我的整个请求，首先我感谢你的时间，其次任何帮助将不胜感激。
