XPATH在javascript上应用问题

程序代码：

<html>

<head>
<title>剩余库存图书</title>
</head>
<Script language='javascript'>
fuction dolast(){ 
   var xmldoc = xmlDSO.XMLDocument;
   xmlDSO.async=false;
   xmldoc.load("book0.xml");
   var nodes = xmlDoc.selectNodes("/books/book/need");
   xmldoc.load("bookseller.xml");
   var nodes1 = xmldoc.selectNodes("books/book/remain");
   for each x in nodes{
      for each y in nodes
         y.text=(String)(parseInt((String)y.text)-parseInt((String)x.text));
   }
   }//存储量减去需求量并把新仓储填入的操作
   </Script>
<body onload="dolast()">
<center>　<p><b><font size="3">图书信息表</font></b></p>
        </center>
     <table datasrc="#xmlDSO" border="1" align="center" id="table2">
     <thead>
        <th>书名</th>
        <th>类别</th>
        <th>书号</th>
        <th>作者</th>
        <th>出版社</th>
        <th>定价</th>
        <th>剩余量</th>
     </thead>
          <tr>
        <td><span DATAFLD="title"></span></td>
        <td><span DATAFLD="bookcategory"></span></td>
        <td><span DATAFLD="ISBN"></span></td>   
        <td><span DATAFLD="author"></span></td>
        <td><span DATAFLD="publisher"></span></td>
        <td><span DATAFLD="price"></span></td>   
        <td><span DATAFLD="remain"></span></td>       
     </tr></table>


</body>

</html>

运行的结果只有表格的表头出现，纳闷啊
