XML看起來像: - 在上述xml文件我是試圖讓二者在不同變量的所有活動和地區使用AJAX的XPath讓孩子和subchild屬性值和存儲變量

<childrens> 
<child_1 entity_id="1" value="Root Catalog" parent_id="0"> 
<child_2 entity_id="2" value="Navigate" parent_id="1"> 
    <child_4 entity_id="4" value="Activities" parent_id="2"> 
     <child_10066 entity_id="10066" value="Physical1" parent_id="4"> 
      <child_10067 entity_id="10067" value="Cricket" parent_id="10066"> 
       <child_10068 entity_id="10068" value="One Day" parent_id="10067"/> 
      </child_10067> 
     </child_10066> 
     <child_10069 entity_id="10069" value="Test2" parent_id="4"/> 
     <child_10070 entity_id="10070" value="Test3" parent_id="4"/> 
     <child_10071 entity_id="10071" value="Test4" parent_id="4"/> 
     <child_10072 entity_id="10072" value="Test5" parent_id="4"/> 
     <child_5 entity_id="5" value="Physical" parent_id="4"/> 
     </child_4> 
    <child_4331 entity_id="4331" value="Region" parent_id="2"> 
     <child_4332 entity_id="4332" value="Asia" parent_id="4331"> 
      <child_4333 entity_id="4333" value="Afghanistan" parent_id="4332"> 
       <child_4334 entity_id="4334" value="Balkh" parent_id="4333"> 
        <child_4335 entity_id="4335" value="Mazar-e-Sharif" parent_id="4334"/> 
       </child_4334> 
       <child_4336 entity_id="4336" value="Herat" parent_id="4333"> 
        <child_4337 entity_id="4337" value="Herat" parent_id="4336"/> 
       </child_4336> 
      </child_4333> 
     </child_4332> 
    </child_4331> 
</child_2> 
</child_1> 
</childrens> 


與此嘗試。

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script> 
<script> 
var result_region=''; 
var node_region; 
var comma_region=''; 
var activity; 
var result_activity=''; 
var node_activity; 
var comma_activity=''; 
var region; 
$(document).ready(function(){ 
$.ajax({ 
       url: 'final.xml', 
       type:"get", 
       async: false, 
       success: function(xml) { 
       var xPath_region = '//child_4/*[@value]' + '/@value'; 
       var xPath_activity = '//child_4331/*[@value]' + '/@value'; 

       var iterator = xml.evaluate(xPath_region, xml.documentElement, null, 
         XPathResult.UNORDERED_NODE_ITERATOR_TYPE, null); 
        var thisNode = iterator.iterateNext(); 
        while (thisNode) { 
        node_region = thisNode.textContent; 
        thisNode = iterator.iterateNext(); 
         if(result_region.indexOf(node_region) == -1){ 
           result_region += comma_region+node_region; 
           comma_region=','; 
       } 
      } 

      var iterator = xml.evaluate(xPath_activity, xml.documentElement, null, 
         XPathResult.UNORDERED_NODE_ITERATOR_TYPE, null); 
        var thisNode = iterator.iterateNext(); 
        while (thisNode) { 
        node_activity = thisNode.textContent; 
        thisNode = iterator.iterateNext(); 
         if(result_activity.indexOf(node_activity) == -1){ 
           result_activity += comma_activity+node_activity; 
           comma_activity=','; 
       } 
      } 
      activity = result_region; 
      region = result_activity; 
      alert(activity); 
      alert(region); 
      }, 
      }); 
}); 
</script> 

上面的代碼返回: -

var activity = "Physical1,Test2,Test3,Test4,Test5"; 
var region = "Asia"; 

其只返回第一級節點b'coz我是試穿的XPath找到Child_4我希望所有的孩子有子節點。
,如: -

var activity = "Physical1,Cricket,One Day,Test2,Test3,Test4,Test5"; 
var region = "Asia,Afghanistan,Balkh,Mazar-e-Sharif,Herat,Herat"; 

我怎樣才能讓所有的孩子和孩子有輔助子值。
謝謝。

你相當接近: 你只有從改變都xpaht表達式:

var xPath_region = '//child_4/*[@value]' + '/@value'; 
var xPath_activity = '//child_4331/*[@value]' + '/@value'; 

到:

var xPath_region = '//child_4//*[@value]' + '/@value'; 
var xPath_activity = '//child_4331//*[@value]' + '/@value'; 

選擇了只child_4室內用值屬性,但你的直接子喜歡選擇child_4的所有後代(//child_4/descendant::*)或短(//child_4//*) 這將輸出以下區域:

"Asia,Afghanistan,Balkh,Mazar-e-Sharif,Herat" 

和活動:

"Physical1,Cricket,One Day,Test2,Test3,Test4,Test5"
