php xml xpath foreach to get values of nodes with same name

Guys,

I have this xml code:

<items>
<item type="boardgame" id="84876">
<versions>
<item type="boardgameversion" id="317166">
<link type="boardgameversion" id="84876" value="The Castles of Burgundy" inbound="true"/>
<name type="primary" sortindex="1" value="Chinese Edition"/>
<link type="boardgamepublisher" id="9068" value="Broadway Toys LTD"/>
<link type="language" id="2181" value="Chinese"/>
</item>

<item type="boardgameversion" id="269360">
<link type="boardgameversion" id="84876" value="The Castles of Burgundy" inbound="true"/>
<name type="primary" sortindex="1" value="Hobby World Russian first edition"/>
<link type="boardgamepublisher" id="18852" value="Hobby World"/>

<link type="boardgameartist" id="4959" value="Harald Lieske"/>
<link type="language" id="2202" value="Russian"/>
</item>

<item type="boardgameversion" id="141049">
<link type="boardgameversion" id="84876" value="The Castles of Burgundy" inbound="true"/>
<name type="primary" sortindex="1" value="Ravensburger English/French Edition"/>
<link type="boardgamepublisher" id="9" value="alea"/>
<link type="boardgamepublisher" id="34" value="Ravensburger Spieleverlag GmbH"/>
<link type="boardgameartist" id="11886" value="Julien Delval"/>
<link type="boardgameartist" id="4959" value="Harald Lieske"/>
<link type="language" id="2184" value="English"/>
<link type="language" id="2187" value="French"/>
</item>

<item type="boardgameversion" id="69303">
<link type="boardgameversion" id="84876" value="The Castles of Burgundy" inbound="true"/>
<name type="primary" sortindex="1" value="Ravensburger Multilingual First Edition"/>
<link type="boardgamepublisher" id="9" value="alea"/>
<link type="boardgamepublisher" id="34" value="Ravensburger Spieleverlag GmbH"/>
<link type="boardgameartist" id="11886" value="Julien Delval"/>
<link type="boardgameartist" id="4959" value="Harald Lieske"/>
<link type="language" id="2184" value="English"/>
<link type="language" id="2187" value="French"/>
<link type="language" id="2188" value="German"/>
</item>

<item type="boardgameversion" id="134173">
<link type="boardgameversion" id="84876" value="The Castles of Burgundy" inbound="true"/>
<name type="primary" sortindex="1" value="Ravensburger Multilingual Second Edition"/>
<link type="boardgamepublisher" id="9" value="alea"/>
<link type="boardgamepublisher" id="34" value="Ravensburger Spieleverlag GmbH"/>
<link type="boardgameartist" id="11886" value="Julien Delval"/>
<link type="boardgameartist" id="4959" value="Harald Lieske"/>
<link type="language" id="2184" value="English"/>
<link type="language" id="2187" value="French"/>
<link type="language" id="2188" value="German"/>
</item>
</versions>
</item>
</items>

I want to get the values of <link type="language"...> for every version item.

My php code is:

$language = $xmlinfo2->item->versions->item;
$lang = $language->xpath('//link[@type="language"]');
$num = 1;

    foreach($language as $lang1) {
       echo $num . ". ";
         foreach ($lang as $lang2){
           $lang3 = $lang2->attributes();
           echo $lang3['value'] . ", ";
         }
         echo "<br>";
         $num++;
    }

Its results is (it writes all languages for all versions out):

1. Chinese, Russian, English, French, English, French, German, English, French, German,

2. Chinese, Russian, English, French, English, French, German, English, French, German,

3. Chinese, Russian, English, French, English, French, German, English, French, German,

4. Chinese, Russian, English, French, English, French, German, English, French, German,

5. Chinese, Russian, English, French, English, French, German, English, French, German,

How do I have to change my php code to get this results?

1. Chinese

2. Russian

3. English, French

4. English, French, German

5. English, French, German

Thank you for your help!
