[C#]對于xml操作代碼封裝

對于XML讀寫操作，項目中經常要用到，之前木有好好總結過，例如LINQ TO XML也用過，這次無意發現XPATH對于XML的查詢極為方便，索性把XML的操作總結以便后續方便使用。

1. 新增XML文件

                XMLToolV2 _xmlHelper = new XMLToolV2(@"C:/20140311blogs.xml");//xml保存路徑或者讀取路徑                _xmlHelper.Create("Person", "utf-8");//跟節點名稱:person;encode:utf-8                XmlElement _person = _xmlHelper.CreateElec("Name", "Yan-Zhiwei");//在跟節點后創建person節點                _xmlHelper.SetAttribute(_person, "Gender", "Man");//設置person節點屬性Gender                _xmlHelper.SetAttribute(_person, "Address", "shanghai");//設置person節點屬性Address                _xmlHelper.Save();//保存xml文件

上述代碼實現效果：

那在Person節點繼續增加節點，實現也很簡單

                _xmlHelper.Create("Person", "utf-8");//跟節點名稱:person;encode:utf-8                XmlElement _person = _xmlHelper.CreateElec("Name", "Yan-Zhiwei");//在跟節點后創建person節點                _xmlHelper.SetAttribute(_person, "Gender", "Man");//設置person節點屬性Gender                _xmlHelper.SetAttribute(_person, "Address", "shanghai");//設置person節點屬性Address                XmlElement _workLh = _xmlHelper.CreateElec(_person, "Work", "shanghai LH");//在person節點下增加work節點                _xmlHelper.SetAttribute(_workLh, "Year", "2013~");//設置work節點屬性Title                XmlElement _workRK = _xmlHelper.CreateElec(_person, "Work", "shanghai Ranking");//在person節點下增加work節點                _xmlHelper.SetAttribute(_workRK, "Year", "2011~2013");//設置work節點屬性Title                _xmlHelper.Save();//保存xml文件

上述代碼實現效果：

2.讀取節點的值，個人感覺xpath方式比linq to xml更為明了方便

                XMLToolV2 _xmlHelper = new XMLToolV2(@"C:/20140311blogs.xml");//xml保存路徑或者讀取路徑                XmlNode _person = _xmlHelper.Select("Person/Name/text()");                Console.WriteLine("Name:" + _person.InnerText);                XmlNode _gender = _xmlHelper.Select("Person/Name[@Gender='Man']");                Console.WriteLine("Gender:" + _gender.Attributes["Gender"].Value);                Console.WriteLine("Address:" + _gender.Attributes["Address"].Value);                Console.WriteLine("-----------------------------");                XmlNodeList _workRecord = _xmlHelper.SelectNodeList("Person/Name/Work");                XMLToolV2.Loop(_workRecord, (XmlNode node) =>                {                    Console.WriteLine("Work:" + node.InnerText + " Year:" + node.Attributes["Year"].Value);                });

上述代碼實現效果：

3.格式化顯示XML

                XMLToolV2 _xmlHelper = new XMLToolV2(@"C:/20140311blogs.xml");//xml保存路徑或者讀取路徑                string _xmlString = _xmlHelper.ShowXml();                Console.WriteLine(XMLToolV2.FormatXml(_xmlString, "utf-8"));

4.XMLToolV2源代碼

    public class XMLToolV2    {        static string _xmlPath;        static XmlDocument _xmlDoc { get; set; }        static XmlElement _xmlRoot;        public XMLToolV2(string xmlPath)        {            _xmlPath = xmlPath;            LoadXmlDoc()
