xml映射为object对象，同时object对象，以xml来表示：
public class Tools
{
private static XmlNodeList SelectNodes(string xpath, string path)
{
XmlDocument doc = new XmlDocument();
doc.Load(path);
return doc.SelectNodes(xpath);
}
private static XmlNode SelectSingleNode(string xpath, string path)
{
XmlDocument doc = new XmlDocument();
doc.Load(path);
return doc.SelectSingleNode(xpath);
} public static T SelectSingle<T>(string selectNode, string path) where T : IxmlToObject<T>, new()
{
T item = new T(); var node = SelectSingleNode(selectNode, path); if (node != null)
{
T obj = item.XmlToObject(node); }
return item;
}
public static void SaveXml(IxmlFormat obj, string path)
{
XmlDocument doc = new XmlDocument();
var xml = obj.ToXml();
doc.LoadXml(xml);
doc.Save(path);
} public static List<T> SelectList<T>(string selectNode,string path) where T:new()
{
List<T> items = new List<T>(); var nodes = SelectNodes(selectNode,path); if (nodes != null)
{
var type = typeof(T);
var properties = type.GetProperties().ToList(); foreach (XmlNode node in nodes)
{
T config = new T(); foreach (XmlAttribute a in node.Attributes)
{
string name = a.Name;
string value = a.Value; var p = properties.FirstOrDefault(t => t.Name.ToLower() == name.ToLower()); if (p != null)
{
p.SetValue(config, value, null);
}
}
items.Add(config);
}
}
return items;
} public static string ReplaceSpecialChars(string content)
{
if (string.IsNullOrEmpty(content)) return ""; string[] specialChars = { "&", "<", ">", "\"", "'" };
string[] entities = { "&", "<", ">", """, "'" }; int i = ;
foreach (var item in specialChars)
{
content = content.Replace(item, entities[i]);
i++;
}
return content;
}
}
这是公共的接口：
public interface IxmlFormat
{
string ToXml();
}
public interface IxmlToObject<T>
{
T XmlToObject(XmlNode node);
}
下面是自定义Object对象对接口的实现：
public class TestCase : IxmlFormat, IxmlToObject<TestCase>
{
public string Title { set; get; }
public string Author { set; get; }
public string BibType { set; get; }
/// <summary>
/// 测试用例路径
/// </summary>
public string FilePath { set; get; } public List<SearchResult> StandardResults { set; get; } public List<SearchResult> SearchResults { set; get; } public string ToXml()
{
var title = Tools.ReplaceSpecialChars(this.Title);
var author = Tools.ReplaceSpecialChars(this.Author);
var bibType = Tools.ReplaceSpecialChars(this.BibType); StringBuilder sb = new StringBuilder(); sb.Append("<?xml version=\"1.0\" encoding=\"utf-8\" ?>"); if (SearchResults != null && SearchResults.Count > )
{
sb.AppendFormat("<case title=\"{0}\" author=\"{1}\" bibType=\"{2}\" >", title, author, bibType); foreach (SearchResult item in SearchResults)
{
sb.AppendFormat("<item title=\"{0}\">", Tools.ReplaceSpecialChars(item.Title)); foreach (var fitem in item.Fields)
{
sb.AppendFormat("<field content=\"{0}\"/>", Tools.ReplaceSpecialChars(fitem));
}
sb.AppendFormat("</item>");
} sb.Append("</case>");
}
return sb.ToString();
} public TestCase XmlToObject(XmlNode node)
{
string title = node.Attributes["title"].Value;
string author = node.Attributes["author"].Value;
string bibType = node.Attributes["bibType"].Value; this.Title = title;
this.Author = author;
this.BibType = bibType; this.StandardResults = new List<SearchResult>();
XmlNodeList itemNodes = node.SelectNodes("//item");
foreach (XmlNode n in itemNodes)
{
var sr = new SearchResult()
{
Title = n.Attributes["title"].Value,
Fields = new List<string>()
}; var fileds = n.ChildNodes; foreach (XmlNode fn in fileds)
{
sr.Fields.Add(fn.Attributes["content"].Value);
}
this.StandardResults.Add(sr);
} return this;
}
} public class SearchResult
{
public string Title { set; get; } public List<string> Fields { set; get; } }
这是一个测试用例，程序从xml文件中读取测试用例，运行测试程序，完成后把结果保存到另外一个xml文件中，这个xml文件结构和测试用例的xml结构一样。我们看看如何读取测试用例：
/// <summary>
/// 读取测试用例
/// </summary>
/// <returns></returns>
private static List<TestCase> GetTestCase(string caseDir)
{
List<TestCase> tests = new List<TestCase>(); var files = Directory.GetFiles(caseDir); foreach (var f in files)
{
var filePath = f;
var testCase = Tools.SelectSingle<TestCase>("//case", filePath);
testCase.FilePath = filePath;
tests.Add(testCase);
} return tests;
}
保存测试结果：
TestCase t = new TestCase()
{
FilePath = viewModel.FilePath,
Author = viewModel.SearchAuthor,
Title = viewModel.SearchTitle,
BibType = viewModel.SearchType,
SearchResults = viewModel.TestResultData,
StandardResults = viewModel.StandardResults
}; string path = viewModel.TestResultFilePath + "\\" + viewModel.ResolveName; if (!Directory.Exists(path)) Directory.CreateDirectory(path); path += "\\" + Path.GetFileNameWithoutExtension(t.FilePath) + "_data.xml"; Tools.SaveXml(t, path);
注意：对象与xml之间的转换，再转为xml时，注意特殊符号的转义，否则会报错。
