Question

我正在使用这个库来解析我的xml：

import xml.etree.cElementTree as xml

解析器的xml输入是subprocess.Popen的输出：

XMLFile = subprocess.Popen(xml_command,shell=True,stdout=subprocess.PIPE, executable="/bin/ksh").communicate()[0]
root = xml.XML(XMLFile)

我收到此错误：

IOError: [Errno 36] File name too long: ' <?xml version=\...'

但是，当我传递与文件相同的命令xml_command生成的xml时，它完全正常：

root = xml.parse("/home/test.xml")

Answer 1

试试这个：

import xml.etree.cElementTree as xml
p = subprocess.Popen(xml_command, shell=True, stdout=subprocess.PIPE, executable="/bin/ksh")
text, err = p.communicate()
root = xml.fromstring(text)

使用python 2.6.6

Store output of subprocess.Popen call in a string

Answer 2

试试这个

from xml.etree.ElementTree import fromstring
root = fromstring(subprocess.check_output(['/bin/ksh']))

无法从Python中的subprocess.Popen输出解析xml
