04-006 Configuration 之 XmlConfigurationSource

添加Key的部分代码：

                        case XmlNodeType.EndElement:
                            if (prefixStack.Any())
                            {
                                // If this EndElement node comes right after an Element node,
                                // it means there is no text/CDATA node in current element
                                if (preNodeType == XmlNodeType.Element)
                                {
                                    var key = string.Join(Constants.KeyDelimiter, prefixStack.Reverse());
                                    data[key] = string.Empty;
                                }

                                prefixStack.Pop();
                            }
                            break;

                        case XmlNodeType.CDATA:
                        case XmlNodeType.Text:
                            {
                                var key = string.Join(Constants.KeyDelimiter, prefixStack.Reverse());

                                if (data.ContainsKey(key))
                                {
                                    throw new FormatException(Resources.FormatError_KeyIsDuplicated(key,
                                        GetLineInfo(reader)));
                                }

                                data[key] = reader.Value;
                                break;
                            }

 示例：

   public void LoadKeyValuePairsFromValidXml()
        {
            var xml = @"
                <settings>
                    <Data.Setting>
                        <DefaultConnection>
                            <Connection.String>Test.Connection.String</Connection.String>
                            <Provider>SqlClient</Provider>
                        </DefaultConnection>
                        <Inventory>
                            <ConnectionString>AnotherTestConnectionString</ConnectionString>
                            <Provider>MySql</Provider>
                        </Inventory>
                    </Data.Setting>
                </settings>";
            var xmlConfigSrc = new XmlConfigurationSource(ArbitraryFilePath);

            xmlConfigSrc.Load(StringToStream(xml));

            Assert.Equal(4, xmlConfigSrc.Data.Count);
            Assert.Equal("Test.Connection.String", xmlConfigSrc.Data["DATA.SETTING:DEFAULTCONNECTION:CONNECTION.STRING"]);
            Assert.Equal("SqlClient", xmlConfigSrc.Data["DATA.SETTING:DefaultConnection:Provider"]);
            Assert.Equal("AnotherTestConnectionString", xmlConfigSrc.Data["data.setting:inventory:connectionstring"]);
            Assert.Equal("MySql", xmlConfigSrc.Data["Data.setting:Inventory:Provider"]);
        }
