解析XML文件

XML文件如下:
<Datas>
   <Item ID="aa" Value="11" />
   <Item ID="bb" Value="22" />
   <Item ID="cc" Value="33" />
   <Table ID="table1" >
         <Row>
             <Col value="11" />
             <Col value="12" />
             <Col value="13" />
         </Row>
         <Row>
             <Col value="21" />
             <Col value="22" />
             <Col value="23" />
         </Row>
         <Row>
             <Col value="31" />
             <Col value="32" />
             <Col value="33" />
         </Row>
   </Table>
   <Table ID="table2" >
         <Row>
             <Col value="11" />
             <Col value="12" />
             <Col value="13" />
         </Row>
         <Row>
             <Col value="21" />
             <Col value="22" />
             <Col value="23" />
         </Row>
         <Row>
             <Col value="31" />
             <Col value="32" />
             <Col value="33" />
         </Row>
   </Table>
</Datas>


解析程序如下:

    private void GetDataFromXml(string strXML)
    {
        try
        {
            Hashtable itemTable = new Hashtable();

            if (strXML == null || strXML.Equals(""))
            {
                return;
            }

            XmlDocument doc = new XmlDocument();
            doc.LoadXml(strXML);

            //解析item
            XmlNodeList itemList = doc.GetElementsByTagName("Item");
            for (int i = 0; i < itemList.Count; i++)
            {
                XmlNode node = itemList[i];
                XmlAttributeCollection nodeAttributes = node.Attributes;
                string strId = nodeAttributes[0].Value;
                string strValue = nodeAttributes[1].Value;
                itemTable.Add(strId, strValue);
            }

            //解析Table
            XmlNodeList tableList = doc.GetElementsByTagName("Table");
            for (int j = 0; j < tableList.Count; j++)
            {
                XmlNode layer1Node = tableList[j];
                string strTableName = layer1Node.Attributes[0].Value;

                XmlNodeList layer2NodeList = layer1Node.ChildNodes;
                for (int k = 0; k < layer2NodeList.Count; k++)
                {
                    XmlNodeList layer3NodeList = layer2NodeList[k].ChildNodes;

                    for (int l = 0; l < layer3NodeList.Count; l++)
                    {
                        XmlNode layer3Node = layer3NodeList[l];
                        XmlAttributeCollection layer3NodeAttributeCollection = layer3Node.Attributes;
                        for (int m = 0; m < layer3NodeAttributeCollection.Count; m++)
                        {
                            XmlAttribute layer3NodeAttribute = layer3NodeAttributeCollection[m];
                            string strLayer3NodeValue = layer3NodeAttribute.Value;
                        }
                    }
                }

            }
        }
        catch (Exception ex)
        {
            lblMessage.Text = ex.Message;
            return;
        }
    }
