示例解决方案:)

var xmlString = $("#tree").jstree("get_xml");   
    var xmlDOM = $.parseXML(xmlString);

    var IDList =[];
var items = $(xmlDOM).find('root item');
$.each (items, function(key, val){
    IDList.push($(val).attr('id'));
})

IDList.pop();

xmlString =

<root>  
        <item id="A" parent_id="0" state="close">  
            <content><name>Charles Madigen</name></content>                
        </item>
        <item id="A1" parent_id="A" state="close">  
            <content><name>Charles Madigen</name></content>                
        </item>
          .
          .
</root>

输出:根，A，A1，A1.1，A1.2，A2，A2.1，A2.2，B，B1，B2，C，C1，C1.1，C2.2
