[C#]對(duì)于xml操作代碼封裝

對(duì)于XML讀寫(xiě)操作，項(xiàng)目中經(jīng)常要用到，之前木有好好總結(jié)過(guò)，例如LINQ TO XML也用過(guò)，這次無(wú)意發(fā)現(xiàn)XPATH對(duì)于XML的查詢極為方便，索性把XML的操作總結(jié)以便后續(xù)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(jié)點(diǎn)名稱:person;encode:utf-8                XmlElement _person = _xmlHelper.CreateElec("Name", "Yan-Zhiwei");//在跟節(jié)點(diǎn)后創(chuàng)建person節(jié)點(diǎn)                _xmlHelper.SetAttribute(_person, "Gender", "Man");//設(shè)置person節(jié)點(diǎn)屬性Gender                _xmlHelper.SetAttribute(_person, "Address", "shanghai");//設(shè)置person節(jié)點(diǎn)屬性Address                _xmlHelper.Save();//保存xml文件

上述代碼實(shí)現(xiàn)效果：

那在Person節(jié)點(diǎn)繼續(xù)增加節(jié)點(diǎn)，實(shí)現(xiàn)也很簡(jiǎn)單

                _xmlHelper.Create("Person", "utf-8");//跟節(jié)點(diǎn)名稱:person;encode:utf-8                XmlElement _person = _xmlHelper.CreateElec("Name", "Yan-Zhiwei");//在跟節(jié)點(diǎn)后創(chuàng)建person節(jié)點(diǎn)                _xmlHelper.SetAttribute(_person, "Gender", "Man");//設(shè)置person節(jié)點(diǎn)屬性Gender                _xmlHelper.SetAttribute(_person, "Address", "shanghai");//設(shè)置person節(jié)點(diǎn)屬性Address                XmlElement _workLh = _xmlHelper.CreateElec(_person, "Work", "shanghai LH");//在person節(jié)點(diǎn)下增加work節(jié)點(diǎn)                _xmlHelper.SetAttribute(_workLh, "Year", "2013~");//設(shè)置work節(jié)點(diǎn)屬性Title                XmlElement _workRK = _xmlHelper.CreateElec(_person, "Work", "shanghai Ranking");//在person節(jié)點(diǎn)下增加work節(jié)點(diǎn)                _xmlHelper.SetAttribute(_workRK, "Year", "2011~2013");//設(shè)置work節(jié)點(diǎn)屬性Title                _xmlHelper.Save();//保存xml文件

上述代碼實(shí)現(xiàn)效果：

2.讀取節(jié)點(diǎn)的值，個(gè)人感覺(jué)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(shí)現(xiàn)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()
