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);
}
privatestatic XmlNode SelectSingleNode(string xpath, string path)
{
XmlDocument doc = new XmlDocument();
doc.Load(path);
return doc.SelectSingleNode(xpath);
}
publicstatic 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;
}
publicstaticvoid SaveXml(IxmlFormat obj, string path)
{
XmlDocument doc = new XmlDocument();
var xml = obj.ToXml();
doc.LoadXml(xml);
doc.Save(path);
}
publicstatic 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;
}
publicstaticstring ReplaceSpecialChars(string content)
{
if (string.IsNullOrEmpty(content)) return"";
string[] specialChars = { "&", "<", ">", "\"", "‘" };
string[] entities = { "&", "<", ">", """, "'" };
int i = 0;
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>
{
publicstring Title { set; get; }
publicstring Author { set; get; }
publicstring BibType { set; get; }
///<summary>/// 测试用例路径
///</summary>publicstring FilePath { set; get; }
public List<SearchResult> StandardResults { set; get; }
public List<SearchResult> SearchResults { set; get; }
publicstring 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 > 0)
{
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);
}
returnthis;
}
}
publicclass SearchResult
{
publicstring 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。
