python - 在 python 中以正确格式输出 XML

Question

代码是:

results = ET.Element("results")
machine = ET.SubElement(results,"machine")
mac = ET.SubElement(machine, "mac")
ip = ET.SubElement(machine,"ip")
name = ET.SubElement(machine,"name")
download = ET.SubElement(machine, "download")
upload = ET.SubElement(machine, "upload")
comments = ET.SubElement(machine, "comments")

for line in lines.split("\n"):
         if 'MAC' in line:
                mac = line.split(":")
                mac.text = str(mac[1].strip())
        if 'IP' in line:
                ip = line.split(":")
                ip.text = str(ip[1].strip())
        if 'NAME' in line:
                name = line.split(":")
                name.text = str(name[1].strip())
        if 'Download' in line:
                down = line.split(":")
                download.text = str(down[1].strip())
        if 'Upload' in line:
                up = line.split(":")
                upload.text = str(up[1].strip())
        if 'Comments' in line:
                user = line.split(":")
                comments.text = str(user[1].strip())

tree = ET.ElementTree(results)
tree.write('machine.xml')

需要转换为 xml 的实际 stdout 输出是

MAC             : 00:19:ec;dc;bc
IP              : 192.111.111.111
NAME            : 900, Charles
Download        : 36MB
Upload          : 12MB
comments        : Since total througput is very less, we cannot continue

MAC             : 00:19:ac:bc:cd:
IP              : 192.222.222.222
NAME            : 800, Babbage
Download        : 36MB
Upload          : 24MB
comments        : Since total througput is high, we can continue

我需要生成的实际格式是

<results>
   <machine>
     <MAC>00:19:ec;dc;bc</MAC>
     <ip>192.111.111.111</ip>
     <name>900, Charles</name>
     <upload>36MB</upload>
     <download>12MB</download>
     <comments>Since total througput is very less, we cannot continue</comments>
   </machine>
   <machine>
     <MAC>00:19:ac:bc:cd:</MAC>
     <ip>192.222.222.222</ip>
     <name>800, Babbage</name>
     <upload>36MB</upload>
     <download>24MB</download>
     <comments>Since total througput is high, we can continue</comments>
   </machine>
</results>

我得到的输出是

<results>
   <machine>
     <MAC>00:19:ec;dc;bc</MAC>
     <ip>192.111.111.111</ip>
     <name>900, Charles</name>
     <upload>36MB</upload>
     <download>12MB</download>
     <comments>Since total througput is very less, we cannot continue</comments>
   </machine>
<machine>
     <MAC>00:19:ec;dc;bc</MAC>
     <ip>192.111.111.111</ip>
     <name>900, Charles</name>
     <upload>36MB</upload>
     <download>12MB</download>
     <comments>Since total througput is very less, we cannot continue</comments>
   </machine>
</results>

我使用的是python 2.4(它很旧，但目前无法升级)。如果有人能提出错误是什么，那就太好了。

谢谢!

您只需创建一次子元素，并在每次运行循环时更改其内容。

每次开始读取新机器时，都会在循环内创建子级。也许在循环外有一个哨兵，并在遇到空行时重置它。
