WP8解析XML格式文件

DOTA2 WebAPI请求返回的格式有两种，一种是XML，一种是JSON，默认是返回JSON格式，如果要返回XML格式的话，需要在加上format=xml。

这里举一个简单的解析XML格式的例子（更多XML操作）：

<response>

<players>

<player>

<steamid>76561198092319753</steamid>

<communityvisibilitystate>1</communityvisibilitystate>

<profilestate>1</profilestate>

<personaname>偶买噶、Scohura</personaname>

<lastlogoff>1396240726</lastlogoff>

<personastate>0</personastate>

</player>

</players>

</response>

解析代码如下，输入Stream流转为String就是上面的文本

        private void prase(Stream xml)

        {

            userdata = XElement.Load(xml).Element("players").Element("player");

            //昵称赋值、溢出部分使用省略号代替

            username.Text = userdata.Element("personaname").Value;

            username.TextTrimming = TextTrimming.WordEllipsis;

            username.FontSize = (this.Height - 80)/3;

            //状态赋值

            switch (userdata.Element("personastate").Value)

            {

                case "0":

                    if (userdata.Element("communityvisibilitystate").Value.Equals("1"))

                    {

                        statusText = "该用户已将资料设为隐私";

                    }

                    else

                    {

                        statusText = "离线";

                    }

                    break;

                case "1":

                    statusText = "在线";

                    break;

                case "2":

                    statusText = "忙碌";

                    break;

                case "3":

                    statusText = "离开";

                    break;

                case "4":

                    statusText = "打盹";

                    break;

                case "5":

                    statusText = "想交易";

                    break;

                case "6":

                    statusText = "想游戏";

                    break;

                default :break;

            }

            status.Text = statusText;

            status.FontSize = (this.Height - 80) / 3;

            //状态辅助赋值

            if (!userdata.Element("personastate").Value.Equals("0"))

            {

                try

                {

                    extraText = userdata.Element("gameextrainfo").Value + "  游戏中";

                    username.Foreground = new SolidColorBrush(Colors.Green);

                    status.Foreground = new SolidColorBrush(Colors.Green);

                    extra.Foreground = new SolidColorBrush(Colors.Green);

                }

                catch

                {

                    username.Foreground = new SolidColorBrush(Colors.Blue);

                    status.Foreground = new SolidColorBrush(Colors.Blue);

                    extra.Foreground = new SolidColorBrush(Colors.Blue);

                }

            }

            else

            {

                extraText = "上次在线时间：";

                username.Foreground = new SolidColorBrush(Colors.Gray);

                status.Foreground = new SolidColorBrush(Colors.Gray);

                extra.Foreground = new SolidColorBrush(Colors.Gray);

            }

            extra.Text = extraText;

            extra.FontSize = (this.Height - 80) / 3;

            //头像赋值

            BitmapImage bitImg = new BitmapImage(new Uri(userdata.Element("avatarfull").Value));

            head.Source = bitImg;

        }　　

 

说明：

以XElement.Load(Stream xml)将Stream转化成XElement形式，而后其子标签，则使用XElement.Element(“Name”)获得，所对应的值为XElement.Value。
