Writing PMD ruleset for XML file

Hi i wanted to write a pmd xpath ruleset for my following lines of code. Can anyone suggest me the possible experience. I tried from everywhere but not able to write the ruleset for this xml content.

My code is:

---

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://ift.tt/nIICcg"
package="com.example.hi"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="18" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity android:name="com.example.imageencryption.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>

1) I have to find the action tag with the condition that it has attribute android:name and its value is set to my said value.

2) I have to find the uses-sdk tag and find the android:minsdkversion with some fixed value. Any suggestion will be appreciated.
