我有一个带有命名空间属性的 XML 文档.XML 看起来像:
I have an XML Document which has attributes with a namespace. The XML looks like:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.sunil.tweet"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="11"
android:targetSdkVersion="16" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.sunil.tweet.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
如何从 activity
标签中提取 android:name
属性?
How can I extract the android:name
attribute from the activity
tag?
获取属性时需要使用命名空间.android
命名空间定义为:
You need to use the namespace when getting the attribute. The android
namespace is defined as:
http://schemas.android.com/apk/res/android
所以你需要将它传递给 attributes()
方法,像这样:
So you need to pass that to the attributes()
method, like this:
$xml = simplexml_load_string($xmlStr);
echo (string) $xml->application->activity->attributes('http://schemas.android.com/apk/res/android')->name;
输出
com.sunil.tweet.MainActivity
com.sunil.tweet.MainActivity
