ASP.NET读取XML文件

一.首先介绍xml 代码如下:

<?xml version="1.0" encoding="utf-8" ?>
<root>
  <company id="6b357589b12f6141fc48c4b0375ef2f9">
    <Wordkey id="5f499e85ed57a5af01fdc0ab05d8b3d2">
     广州
    </Wordkey>
  </company>
  <company id="8ebd5d853db2ee913b3c1bf685741b52">
    <Wordkey id="77bf607cefce3aea33913505dca3bfdb">
     深圳
    </Wordkey>
  </company>
  <!--全部-->
  <company id="a8b0c20416853bda54120bf19477ad11">
    <Wordkey id="1e5142e81a34260029e8dc84c21d00d3">
      北京,上海,广州,深圳,珠海,东莞,青岛,连云港市
    </Wordkey>
  </company>
</root>

二.读取文件:

 public class NewWebsiteHomeLogic
    {

        #region 当前类的实例

        private static readonly NewWebsiteHomeLogic logicInstances = new NewWebsiteHomeLogic();
        private NewWebsiteHomeLogic() { }
        public static NewWebsiteHomeLogic GetInstances()
        {
            return logicInstances;
        }

        #endregion


        #region 获取关键字的列表
        /// <summary>
        /// 获取关键字的列表
        /// </summary>
        /// <param name="companyID">用户所属公司ID</param>
        /// <returns></returns>
        public string[] GetDependencyList(string companyID)
        {
            return GetDependencyList(companyID, string.Empty);
        }
        #endregion




        #region 获取关键字的列表
        /// <summary>
        ///获取关键字的列表
        /// </summary>
        /// <param name="companyID">用户所属公司id</param>
        /// <param name="wordkeyID">关键字ID</param>
        /// <returns></returns>
        public string[] GetDependencyList(string companyID, string wordkeyID)
        {
            if (string.IsNullOrEmpty(companyID))
            {
                return null;
            }

            XmlDocument doc = GetDocument();
            XmlNode node = GetNode(companyID, wordkeyID, doc);

            if (string.IsNullOrEmpty(node.InnerText) || node == null)
            {
                return null;
            }

            var xmlNodeText = node.InnerText;

            xmlNodeText = xmlNodeText.Replace("\r", string.Empty).Replace("\n", string.Empty).Replace(" ", string.Empty);

            xmlNodeText = Core.Utility.FilterRepeatItem(xmlNodeText, new char[] { ',' });

            var array = xmlNodeText.Split(new char[] { ',' });

            return array;
        }

        #endregion

        #region 获取xml节点
        private XmlNode GetNode(string companyID, string wordkeyID, XmlDocument doc)
        {
            if (string.IsNullOrEmpty(companyID) || doc == null)
            {
                return null;
            }
            XmlNode node = null;
            string xpath = "/root/company[@id='" + companyID + "']";
            node = doc.SelectSingleNode(xpath);
            if (node == null || node.HasChildNodes == false)
            {
                return null;
            }

            if (string.IsNullOrEmpty(wordkeyID))
            {
                xpath += "/Wordkey[@id='0']";
            }
            else
            {
                xpath += "/Wordkey[@id='" + wordkeyID + "']";
            }


            if ((node == null || string.IsNullOrEmpty(node.InnerText)) && string.IsNullOrEmpty(wordkeyID) == false)
            {
                return GetNode(companyID, string.Empty, doc);
            }
            return node;

        }
        #endregion

        #region 获取xml文件
        private XmlDocument GetDocument()
        {
            XmlDocument doc = null;
            string path = System.Web.HttpContext.Current.Server.MapPath("~/config/NewWebsiteHome.xml");
            if (string.IsNullOrEmpty(path))
            {
                return null;
            }
            else
            {
                doc = new XmlDocument();
                doc.Load(path);
            }
            return doc;

        }

        #endregion

    }

三.获取数据

 

            string[] strdepens = NewWebsiteHomeLogic.GetInstances().GetDependencyList(companyID, wordkeyID);


            string words = "";
            if (strdepens.Count() > 0)
            {
                int count = strdepens.Count();
               
                for (int i = 0; i < count; i++)
                {

                    if (i < count - 1)
                    {
                        words += (strdepens[i] + "|");
                    }
                    else
                    {
                        words += (strdepens[i]);
                    }

                }
            }

            

        }
