如何使用minidom从非字符串数据类型生成xml?我有一种感觉,有人会告诉我事先生成字符串,但这不是我追求的。

from datetime import datetime
from xml.dom.minidom import Document

num = "1109"
bool = "false"
time = "2010-06-24T14:44:46.000"

doc = Document()

Submission = doc.createElement("Submission")
Submission.setAttribute("bool",bool)
doc.appendChild(Submission)

Schedule = doc.createElement("Schedule")
Schedule.setAttribute("id",num)
Schedule.setAttribute("time",time)
Submission.appendChild(Schedule)

print doc.toprettyxml(indent="  ",encoding="UTF-8")

结果如下:

<?xml version="1.0" encoding="UTF-8"?>
<Submission bool="false">
  <Schedule id="1109" time="2010-06-24T14:44:46.000"/>
</Submission>

如何获得非字符串数据类型的有效xml表示?

from datetime import datetime
from xml.dom.minidom import Document

num = 1109
bool = False
time = datetime.now()

doc = Document()

Submission = doc.createElement("Submission")
Submission.setAttribute("bool",bool)
doc.appendChild(Submission)

Schedule = doc.createElement("Schedule")
Schedule.setAttribute("id",num)
Schedule.setAttribute("time",time)
Submission.appendChild(Schedule)

print doc.toprettyxml(indent="  ",encoding="UTF-8")

_write_data中的文件“C:\ Python25 \ lib \ xml \ dom \ minidom.py”,第299行     data = data.replace(“&amp;”,“&amp;”)。replace(“&lt;”,“&lt;”) AttributeError:'bool'对象没有属性'replace'

绑定方法setAttribute期望其第二个参数值为字符串。您可以通过将数据转换为字符串来帮助完成此过程:

bool = str(False)

或在致电setAttribute时转换为字符串:

Submission.setAttribute("bool",str(bool))

(当然,numtime也必须这样做。
