我需要打印的是 ECG 已启用、NIBP 已启用等.

what i need to print is ECG is Enabled , NIBP is enabled etc..

我使用的代码添加在下面.由于某些依赖性，我需要更新相同的代码.需要在代码中提到的print处添加代码(这里需要添加代码)

the code i used is added below. I need to update the same code because of some dependency. need to add the code at print(Need to add the code here) mentioned in the code

import sys
import xml.dom.minidom as XY

file = open("Result_Summary.txt", "w")
tree = XY.parse('Results-On-2013-01-22_0659.xml')
#print (str(sys.argv[1]))
#tree = XY.parse(sys.argv[1])

Test_name = tree.getElementsByTagName('test')
count_testname =0
    file.write(' -----------------------------------------------------------------------------------------------------\n\n')
file.write('\tTest Name \t\t No Of PASS\t\t No Of FAIL\t\t\t Description\t\t \n')
file.write(' -----------------------------------------------------------------------------------------------------\n\n')
for my_Test_name in Test_name:
    count_testname = count_testname+1
    my_Test_name_final = my_Test_name.getAttribute('name')
    if(count_testname > 1):
        #print(my_Test_name_final)
        file.write(my_Test_name_final)
        file.write('\t\t\t')
        my_Test_status = my_Test_name.getElementsByTagName('result')
        passcount = 0
        failcount = 0
        for my_Test_status_1 in my_Test_status:
            my_Test_description = my_Test_name.getElementsByTagName('description')
            for my_Test_description_1 in my_Test_description:
                my_Test_description_final = my_Test_description_1.getAttribute('type')
                print(Need to add the code here)
                my_Test_status_final = my_Test_status_1.getAttribute('type')
                if(my_Test_status_final == 'PASS'):
                   passcount = passcount+1
                if(my_Test_status_final == 'FAIL'):
                   failcount = failcount+1
            #print(str(my_Test_status_final))
        file.write(str(passcount))
        #print(passcount)
        file.write('\t\t\t')
        file.write(str(failcount))

前

pected result

tst_Setup_menu_2     8        0        ECG Enabled
                                       p1 Enabled
                                       P2 Enabled etc

推荐答案

扩展我的 以前的答案，请务必将 ElementTree API 用于此类任务:

Expanding on my previous answer, please do use the ElementTree API for such tasks:

from xml.etree import ElementTree as ET

tree = ET.parse(r'D:\Squish\squish results\Results-On-2013-01-18_0241 PM.xml')

with open("Result_Summary.txt", "w") as output:
    output.write(' {} \n\n'.format('-' * 101))
    output.write('\tTest Name \t\t No Of PASS\t\t No Of FAIL\t\t\t Description\t\t \n')
    output.write(' {} \n\n'.format('-' * 101))

    # Find all <test> elements with a <verification> child:
    for test in tree.findall('.//test[verification]'):
        # Collect passed and failed counts
        passed = len(test.findall(".//result[@type='PASS']"))
        failed = len(test.findall(".//result[@type='FAIL']"))
        # Collect all the *last* <description> elements of type DETAILED
        descriptions = test.findall(".//result/description[@type='DETAILED'][last()]")
        # write a line of information to the file, including first desc
        output.write('{0}\t\t\t{1}\t\t\t{2}\t\t\t{3}\n'.format(
            test.attrib['name'], passed, failed, descriptions[0].text))
        # write remaining descriptions
        for desc in descriptions[1:]:
            output.write('\t\t\t\t\t\t\t\t\t{0}\n'.format(desc.text))
