在python中读取xml

本文介绍了在python中读取xml的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <soap:Body>
        <LoginResponse xmlns="http://tempuri.org/">
            <LoginResult>true</LoginResult>
            <aSessionID>AF-6A-51-FD-E6-8D-C8-12-AB-7E-C1-BD-50-7A-43-D0-AA-27-15-CA</aSessionID>
        </LoginResponse>
    </soap:Body>
</soap:Envelope>

这个xml格式来自sope api我想从这个读取xml aSessionID.请帮我在python中做到这一点

This xml format coming form sope api i want to read xml aSessionID form this. Please help me to do this in python

推荐答案

list_test.xml:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <soap:Body>
        <LoginResponse xmlns="http://tempuri.org/">
            <LoginResult>true</LoginResult>
            <aSessionID>AF-6A-51-FD-E6-8D-C8-12-AB-7E-C1-BD-50-7A-43-D0-AA-27-15-CA</aSessionID>
            <aSessionID>54F-6A-51-FD-E6-8D-C8-45-AB-7E-C1-BD-50-7A-43-D0-AA-27-15-65</aSessionID>
        </LoginResponse>
    </soap:Body>
</soap:Envelope>

然后:

from xml.dom import minidom

doc = minidom.parse("list_test.xml")
sessionList = doc.getElementsByTagName('aSessionID')

for sess in sessionList:
    print(sess.firstChild.nodeValue)

输出:

AF-6A-51-FD-E6-8D-C8-12-AB-7E-C1-BD-50-7A-43-D0-AA-27-15-CA
54F-6A-51-FD-E6-8D-C8-45-AB-7E-C1-BD-50-7A-43-D0-AA-27-15-65

编辑:

要从 string 而不是文件中读取 xml，您可以使用:

To read the xml from a string rather than the file, you may use:

minidom.parseString(xml_str)

因此:

from xml.dom import minidom

xml_str = '''<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <soap:Body>
        <LoginResponse xmlns="http://tempuri.org/">
            <LoginResult>true</LoginResult>
            <aSessionID>AF-6A-51-FD-E6-8D-C8-12-AB-7E-C1-BD-50-7A-43-D0-AA-27-15-CA</aSessionID>
            <aSessionID>54F-6A-51-FD-E6-8D-C8-45-AB-7E-C1-BD-50-7A-43-D0-AA-27-15-65</aSessionID>
        </LoginResponse>
    </soap:Body>
</soap:Envelope>'''
doc = minidom.parseString(xml_str)
sessionList = doc.getElementsByTagName('aSessionID')

for sess in sessionList:
    print(sess.firstChild.nodeValue)

输出:

AF-6A-51-FD-E6-8D-C8-12-AB-7E-C1-BD-50-7A-43-D0-AA-27-15-CA
54F-6A-51-FD-E6-8D-C8-45-AB-7E-C1-BD-50-7A-43-D0-AA-27-15-65
