修改xml的屬性值

# coding=utf-8

import os
import os.path
import xml.dom.minidom
#更改xml檔案中name和folder屬性值
path =
"f:/mx_matting/ssd.pytorch-master/data/vocdevkit/voc2007/annotations"
files = os.listdir(path)
# 得到資料夾下所有檔名稱
for xmlfile in files:
# 遍歷資料夾
ifnot os.path.isdir(xmlfile)
:# 判斷是否是資料夾,不是資料夾才開啟
print
(xmlfile)
# 將獲取的xml檔名送入到dom解析
dom = xml.dom.minidom.parse(os.path.join(path, xmlfile)
)# 輸入xml檔案具體路徑
root = dom.documentelement
# 獲取標籤以及的值
name = root.getelementsbytagname(
'name'
)        folder = root.getelementsbytagname(
'folder'
)# 對每個xml檔案的多個同樣的屬性值進行修改。此處將每乙個屬性修改為plane,每乙個屬性修改為voc2007
for i in
range
(len
(name)):
print
(name[i]
.firstchild.data)
name[i]
.firstchild.data =
'person'
print
(name[i]
.firstchild.data)
for i in
range
(len
(folder)):
print
(folder[i]
.firstchild.data)
folder[i]
.firstchild.data =
'voc2007'
print
(folder[i]
.firstchild.data)
# 將屬性儲存至xml檔案中
with
open
(os.path.join(path, xmlfile)
,'w'
)as fh:
dom.writexml(fh)
print
('已寫入'
)
