我试图从url解析xml。在

一开始我的代码是这样的:from xml.dom import minidom

xmldoc = minidom.parse('all.xml')

Sensor0Elm = xmldoc.getElementsByTagName('t0')

Sensor1Elm = xmldoc.getElementsByTagName('t1')

Sensor2Elm = xmldoc.getElementsByTagName('t2')

Sensor0Elm = Sensor0Elm[0]

Sensor1Elm = Sensor1Elm[0]

Sensor2Elm = Sensor2Elm[0]

Sensor0 = Sensor0Elm.childNodes[0].data

Sensor1 = Sensor1Elm.childNodes[0].data

Sensor2 = Sensor2Elm.childNodes[0].data

Sensor0 = float(Sensor0)

Sensor1 = float(Sensor1)

Sensor2 = float(Sensor2)

在这个例子中，我想分析一下xml文件在我的本地硬盘上，结果非常完美！

下一步是从url解析xml。allnet传感器将继续使用xml通过可访问浏览器访问以下数据插入网络url:192.168.60.242/xml

这是嵌入的xml：

^{pr2}$

所以我把代码改成：import urllib

import time

while True:

### XML Extraction ###

from xml.dom import minidom

allxml = urllib.urlopen("http://192.168.60.242/xml")

allxml_string = allxml.read()

allxml.close()

print allxml_string

xmldoc = minidom.parseString(allxml_string)

Sensor0Elm = xmldoc.getElementsByTagName('t0')

Sensor1Elm = xmldoc.getElementsByTagName('t1')

Sensor2Elm = xmldoc.getElementsByTagName('t2')

Sensor0Elm = Sensor0Elm[0]

Sensor1Elm = Sensor1Elm[0]

Sensor2Elm = Sensor2Elm[0]

Sensor0 = Sensor0Elm.childNodes[0].data

Sensor1 = Sensor1Elm.childNodes[0].data

Sensor2 = Sensor2Elm.childNodes[0].data

Sensor0 = float(Sensor0)

Sensor1 = float(Sensor1)

Sensor2 = float(Sensor2)

不幸的是，它不起作用。如实施，将返回以下内容：

(通过使用print()函数，可以xml正确插入te程序。唯一的问题似乎是parse进一步处理函数。
