JQuery中, 如何将一组从XML中取得的值赋值给一组<td>中.

            // 加载xml文档，读取所有的尺码
            $.get("product_store_detail_get_v2.ashx", { style_sheet_id: 1555, type: "size" }, function(data) {
            
                alert($(data).find("size").length);                
             
            });            $("#tableA [size]").length;$(data).find("size") 得到的是一个xml, 如下所示:
  <?xml version="1.0" encoding="UTF-8" ?> 
- <job_sheet_product>
- <size_all>
  <size>5I</size> 
  <size>2</size> 
  <size>4</size> 
  <size>6</size> 
  <size>7</size> 
  <size>8</size> 
  <size>9</size> 
  <size>10</size> 
  <size>11</size> 
  <size>12</size> 
  <size>14</size> 
  <size>3F</size> 
  <size>5F</size> 
  <size>7F</size> 
  </size_all>
  </job_sheet_product>
 $("#tableA [size]") 得到的是一组<th>,如下    <table id="tableA" class="verdana12pt" border="0" cellpadding="2" cellspacing="1"
        style="background-color: #666666; width: 100%;">
        <tr align="center" style="background-color: #999999;">
            <th rowspan="2">
                颜色/花号
            </th>
            <th colspan="9">
                尺码分配
            </th>
            <th rowspan="2">
                数量
            </th>
            <th rowspan="2">
                A品库存原因
            </th>
        </tr>
        <tr align="center" style="background-color: #999999;">
            <th style="width: 7%;" size="0">
                &nbsp;
            </th>
            <th style="width: 7%;" size="0">
                &nbsp;
            </th>
            <th style="width: 7%;" size="0">
                &nbsp;
            </th>
            <th style="width: 7%;" size="0">
                &nbsp;
            </th>
            <th style="width: 7%;" size="0">
                &nbsp;
            </th>
            <th style="width: 7%;" size="0">
                &nbsp;
            </th>
            <th style="width: 7%;" size="0">
                &nbsp;
            </th>
            <th style="width: 7%;" size="0">
                &nbsp;
            </th>
            <th style="width: 7%;" size="0">
                &nbsp;
            </th>
        </tr>
