如何在Python中使用ElementTree获取XML元素文本

我有这样一些xml：

XML比这个要大得多，我在本例中将其缩短。这是我到目前为止所拥有的。如何获取文档元素文本

import xml.etree.ElementTree as ET

tree = ET.parse('../App/Logs/output.xml')

root = tree.getroot()

testName = []
testDoc = []

for test in root.iter('test'):
    testName.append(test.get('name'))
    #somehow get the test doc text here

print testName

如果要使用，您可以通过以下方式解决：

将打印：

{'Verify Buildings Page': 'Verifies the Admin, Setup, Buildings Page'}

import lxml.etree as ET

tree = ET.parse("input.xml")
root = tree.getroot()

result = {
    test.attrib['name']: test.xpath("following-sibling::doc")[0].text
    for test in root.iter('test')
}
print(result)

{'Verify Buildings Page': 'Verifies the Admin, Setup, Buildings Page'}
