用jquery分析XML时出现问题

我正在尝试使用jquery从SharePointService(列表)解析XML。 我有XMLHttpRequest对象扩展数据,它包含ResponseXML属性,即IXMLDOMDocument2。

xdata.responseText具有以下值:

    <?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<GetListItemsResponse xmlns="http://schemas.microsoft.com/sharepoint/soap/"><GetListItemsResult>
<listitems xmlns:s='uuid:BDC6E3F0-6DA3-11d1-A2A3-00AA00C14882'
         xmlns:dt='uuid:C2F41010-65B3-11d1-A29F-00AA00C14882'
         xmlns:rs='urn:schemas-microsoft-com:rowset'
         xmlns:z='#RowsetSchema'>
    <rs:data ItemCount="2">
       <z:row ows_Title='Bosna i Hercegovina' ows_MetaInfo='1;#' ows__ModerationStatus='0' ows__Level='1' ows_ID='1' ows_owshiddenversion='1' ows_UniqueId='1;#{05EC6AB5-D1C6-4CCE-8B70-5FF7B922AE6A}' ows_FSObjType='1;#0' ows_Created='2010-10-29 15:59:59' ows_FileRef='1;#sites/state/Lists/CountryOfResidence/1_.000' />
       <z:row ows_Title='Hrvatska' ows_MetaInfo='2;#' ows__ModerationStatus='0' ows__Level='1' ows_ID='2' ows_owshiddenversion='1' ows_UniqueId='2;#{45FA88C3-17AF-4135-A926-6BE0C878EAAF}' ows_FSObjType='2;#0' ows_Created='2010-10-29 16:02:18' ows_FileRef='2;#sites/state/Lists/CountryOfResidence/2_.000' />
    </rs:data>
    </listitems>
</GetListItemsResult>
</GetListItemsResponse>
</soap:Body>
</soap:Envelope>

我使用以下代码:

$(xData.responseXML).find("z:row").each(function () {
    var liHtml = "" + $(this).attr("ows_Title") + "";
    alert(liHtml);
    $("#tasksUL").append(liHtml);
   });

实际上,它什么也不做。这是因为$(xdata.responsexml).find(“z:row”).length为0,而只有$(xdata.responsexml).find(“*”)的长度不是0(在本例中是8)。

所以,我的问题是jquery find函数,它不识别我拥有的XML节点,我找不到任何人有类似的问题。
