C#解析XML超长字符串的问题！高分求助！！
我不太了解XML，现有如下字符串在 <itemData> ... </itemData> ,中有100件物品，请教各位如何批量获取每件物品的属性，并根据itemInfo，对ACCESS执行SQL语句？
字符串是连在一起的，为了查看方便，我写成如下格式。
<root>
<iteminfo>
<add   key= "actionWord "   value= "insert "   />
<add   key= "itemNum "   value= "100 "   />
</iteminfo>
<itemData>
<cell   item= "1 ">
<add   key= "frequency "   value= "1 "   />
<add   key= "itemname "   value= "AAAA "   />
<add   key= "color "   value= "4 "   />
<add   key= "level "   value= "37 "   />
<add   key= "type "   value= "DX "   />
<add   key= "lengh "   value= "4 "   />
<add   key= "p1 "   value= "you5 "   />
<add   key= "p2 "   value= "xia2 "   />
<add   key= "p3 "   value= "tou2 "   />
<add   key= "p4 "   value= "kui1 "   />
<add   key= "p5 "   value= " "   />
<add   key= "p6 "   value= " "   />
<add   key= "p7 "   value= " "   />
<add   key= "p8 "   value= " "   />
<add   key= "p9 "   value= " "   />
<add   key= "p10 "   value= " "   />
</cell>
                                    <cell   item= "2 ">
<add   key= "frequency "   value= "1 "   />
<add   key= "itemname "   value= "XXXX "   />
<add   key= "color "   value= "4 "   />
<add   key= "level "   value= "37 "   />
<add   key= "type "   value= "ADD "   />
<add   key= "lengh "   value= "4 "   />
<add   key= "p1 "   value= "you5 "   />
<add   key= "p2 "   value= "xia2 "   />
<add   key= "p3 "   value= "tou2 "   />
<add   key= "p4 "   value= "kui1 "   />
<add   key= "p5 "   value= " "   />
<add   key= "p6 "   value= " "   />
<add   key= "p7 "   value= " "   />
<add   key= "p8 "   value= " "   />
<add   key= "p9 "   value= " "   />
<add   key= "p10 "   value= " "   />
</cell>
                                      .........
</itemData>
</root>
