C#操作XML文件

XML文档结构

<?xml version="1.0" encoding="utf-8"?>
<Date>
  <AddLogDate Date="6">
  </AddLogDate>
  <ModifiyDate Date="4">
  </ModifiyDate>
  <DeleteDate Date="3">
  </DeleteDate>
</Date>

以下方法是多XML文件进行属性设置的代码.

        string xmlpath = Server.MapPath(".") + "/DataXml/Date.xml";
        XmlDocument xmldoc = new XmlDocument();
        xmldoc.Load(xmlpath);

        XmlNodeList topm = xmldoc.DocumentElement.ChildNodes;
        foreach (XmlElement element in topm)
        ...{
            if (element.Name == "AddLogDate")
            ...{
                if (this.txtAddDay.Text.Trim() != "")
                ...{
                    element.SetAttribute("Date", this.txtAddDay.Text);
                }
                else
                ...{
                    element.SetAttribute("Date",Adate.ToString());
                }
            }
            if (element.Name == "ModifiyDate")
            ...{
                if (this.txtAddDay.Text.Trim() != "")
                ...{
                    element.SetAttribute("Date", this.txtModityDay.Text);
                }
                else
                ...{
                    element.SetAttribute("Date", Mdate.ToString());
                }
            }
            if (element.Name == "DeleteDate")
            ...{
                if (this.txtAddDay.Text.Trim() != "")
                ...{
                    element.SetAttribute("Date", this.txtDeleteDay.Text);
                }
                else
                ...{
                    element.SetAttribute("Date", Mdate.ToString());
                }
            }
        }
        xmldoc.Save(xmlpath);

获取xml中指定节点属性:

    /**//// <summary>
    /// 获取节点中属性值
    /// </summary>
    /// <param name="xmlNodeName"></param>
    /// <param name="attributesName"></param>
    /// <returns></returns>
    protected int GetDays(string xmlNodeName, string attributesName)
    ...{
        string xmlpath = Server.MapPath(".") + "/DataXml/Date.xml";
        XmlDocument xmldoc = new XmlDocument();
        xmldoc.Load(xmlpath);
        int day = 0;
        XmlNodeList topm = xmldoc.DocumentElement.ChildNodes;
        foreach (XmlElement element in topm)
        ...{
            if (element.Name == xmlNodeName)
            ...{
                day = int.Parse(element.Attributes[attributesName].Value);
            }
        }
        return day;
    }
