Python——使用ElementTree解析AndroidManifest.xml檔案

標籤：python elementtree xml

1. XML內容如下：

<?xml version="1.0" encoding="utf-8" standalone="no"?><manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.dongbao.wauoen.interappactivitytesting" platformBuildVersionCode="23" platformBuildVersionName="6.0-2704002">    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>    <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:supportsRtl="true" android:theme="@style/AppTheme">        <activity android:exported="true" android:name="com.dongbao.wauoen.interappactivitytesting.MainActivity">            <intent-filter>                <action android:name="android.intent.action.MAIN"/>                <category android:name="android.intent.category.LAUNCHER"/>            </intent-filter>        </activity>        <activity android:enabled="@bool/use_activity" android:exported="true" android:icon="@drawable/ic_chooser" android:label="@string/choose_file" android:name="com.ipaulpro.afilechooser.FileChooserActivity"/>        <activity android:exported="true" android:name="com.dongbao.wauoen.interappactivitytesting.ExampleActivity" android:permission="android.permission.READ_EXTERNAL_STORAGE"/>    </application></manifest>

2.解析過程：主要擷取開放activity的資訊，並儲存到xml檔案中

from ActivityInfo import ActivityInfotry:    import xml.etree.cElementTree as ETexcept ImportError:    import xml.etree.ElementTree as ETimport sys# Manifest namespacenamespace = ‘{http://schemas.android.com/apk/res/android}‘# Exported activitiesexported_activities = []# XML analyzedef __xml_analyze__():    tree = ET.parse(r"./app/AndroidManifest.xml")    root = tree.getroot()    # print tree.namespace    # 1.get package name    packagename = root.attrib["package"]    # 2.get exported activity    application = root.find("application")    __get_exported_activities__(application, packagename)    for activity in exported_activities:        print activity.__get_name__(), activity.__get_package_name__(), activity.__get_permission__()    # 3.save result to xml file    __save_result_to_xml__()# get exported activitiesdef __get_exported_activities__(application, packagename):    for activity in application:        # 2.1 MainActivity name        if __is_main_activity__(activity):            name = activity.attrib[namespace+‘name‘]            main_activtiy = ActivityInfo(name)            main_activtiy.__set_package_name__(packagename)            if activity.find(namespace+‘permission‘) is not None:                permission = activity.attrib[name+‘permission‘]                main_activtiy.__set_permission__(permission)            exported_activities.append(main_activtiy)        else:            # 2.1 exported activities except mainactivtiy            exported = activity.attrib[namespace+‘exported‘]            if exported:                activity_name = activity.attrib[namespace+‘name‘]                exported_activity = ActivityInfo(activity_name)                exported_activity.__set_package_name__(packagename)                permission = activity.attrib.get(namespace+‘permission‘, None)                if permission is not None:                    # permission = activity.attrib[name+‘permission‘]                    # print permission                    exported_activity.__set_permission__(permission)                exported_activities.append(exported_activity)# save result to xml filedef __save_result_to_xml__():    tree = ET.ElementTree()    root = ET.Element(‘data‘)    tree._setroot(root)    for activity in exported_activities:        node = ET.Element(‘activity‘)        node.set(‘name‘, activity.__get_name__())        node.set(‘packagename‘, activity.__get_package_name__())        root.append(node)        if activity.__get_permission__() is not None:            node.set(‘permission‘, activity.__get_permission__())    tree.write("output.xml")# the activity is or not MainActivitydef __is_main_activity__(activity):    intent_filter = activity.find("intent-filter")    if intent_filter is not None:        action = intent_filter.find(‘action‘)        category = intent_filter.find(‘category‘)        if action is not None and category is not None                 and action.attrib[namespace + "name"] == ‘android.intent.action.MAIN‘                and category.attrib[namespace + "name"] == ‘android.intent.category.LAUNCHER‘:            print ‘this is main activity‘            return True    return False# main funif __name__ == "__main__":    __xml_analyze__()

3.ActivityInfo 

class ActivityInfo:    def __init__(self, name):        self.name = name        self.package_name = ‘‘        self.permission = ‘‘    def __set_package_name__(self, package_name):        self.package_name = package_name    def __get_package_name__(self):        return self.package_name    def __set_name__(self, name):        self.name = name    def __get_name__(self):        return self.name    def __set_permission__(self, permission):        self.permission = permission    def __get_permission__(self):        return self.permission
