我正在尝试在字典中添加一个 xml 文件。现在我想做的是在不丢失值的情况下将值更新到字典中。这样做的原因是我想对 xml 文件进行分组以显示标签作者所做的所有更改。
这是 xml 文件的示例。
<log>
<logentry
revision="33185">
<author>glv</author>
<date>2012-08-06T21:01:52.494219Z</date>
<paths>
<path
kind="file"
action="M">/branches/Patch_4_2_0_Branch/text.xml</path>
<path
kind="dir"
action="M">/branches/Patch_4_2_0_Branch</path>
</paths>
<msg>PATCH_BRANCH:N/A
BUG_NUMBER:N/A
FEATURE_AFFECTED:N/A
OVERVIEW:N/A
Adding the SVN log size requirement to the branch
</msg>
</logentry>
....
</log>
这是我用 Python 编写的代码。
from xml.dom import minidom
import smtplib
from email.mime.text import MIMEText
from datetime import datetime
def xml_data ():
f = open('C:\opidea_2.xml', 'r')
data = f.read()
f.close()
dom = minidom.parseString(data)
ic = (dom.getElementsByTagName('logentry'))
dom = None
content = ''
author = {}
for num in ic:
authors = num.getElementsByTagName('author')
if len(authors) > 0:
name = authors[0].firstChild.nodeValue
author.update({'author': str(name)})
datef = []
xmlDate = num.getElementsByTagName('date')[0].firstChild.nodeValue
datef = [Good_Time]
path_change = []
paths = [x for x in num.getElementsByTagName("paths")[0].childNodes if isinstance(x, minidom.Element)]
for path in paths:
x = path.childNodes[0].nodeValue
if str(path.getAttribute("kind")) == 'dir':
path_change ='Directory location: ' + [str(x)]
else:
path_change ='Filename: ' + [str(x)]
xmlMsgf = []
xmlMsg = num.getElementsByTagName('msg')
if xmlMsg !='' and len(xmlMsg) > 0:
xmlMsgc = xmlMsg[0].firstChild.nodeValue
xmlMsgf = [xmlMsgc]
else:
xmlMsgc = "No comment made."
xmlMsgf = [xmlMsgc]
authorentry.push{('author',authorA),('date',datef),('path',path_change),('path',xmlMsgf))}
for k, v in [(authorentry)]:
try:
author[k].append(v)
except KeyError:
author[k] = [v]
author.update({'Date':datef,'Path':path_change,'msg':str(xmlMsgf)})
print author
if __name__ == "__main__":
xml_data ()
现在我想要的最终结果是这样的
键 1 = glv , date1 ,path 1a path 1b , msg1 , date2 , path 2 , msg 2 , ...
键 2 = jsm,日期 1,路径 1,味精 1。
我想将 author.update({'Date':datef,'Path':path_change,'msg':str(xmlMsgf)}) 分组以列出作者的 xml 文件,以附加作者制作的下一组内容. 不太清楚该怎么做。任何帮助,将不胜感激。这是我更新的代码,但我现在似乎收到了无效的语法错误:
line 151
authorentry.push{('author',authorA),('date',datef),('path',path_change),('path',xmlMsgf))}
