Question

我目前正在创建一个API，它接受像“sample input”这样的字符串作为输入参数。此API应该调用其他第三方API传递与输入相同的值，如

 https://thirdpartyhost/api/dept?name=sample+input

返回xml，如

<lab:labs>
<lab uri="https://thirdpartyhost/api/dept/1">
 <name>sample input</name></lab>
</lab:labs>

我需要从<lab uri="https://thirdpartyhost/api/dept/1">检索uri，这将为我们提供所需的响应。

 public IHttpActionResult Get(string DeptName)
    {
        using (var client = new HttpClient())
        {
            string BaseURL = ConfigurationManager.AppSettings["BaseURL"];
            Uri uri = new Uri(BaseURL);
            client.BaseAddress = uri;
            client.DefaultRequestHeaders.Accept.Clear();
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/xml"));
            var response = client.GetAsync("api/v2/dept?name=" +LabName).Result;
            if (response.IsSuccessStatusCode)
            {
                string responseString = response.Content.ReadAsStringAsync().Result;
            }
        }

我不确定如何从API的响应中提取uri。非常感谢任何帮助

Answer 1

使用AngleSharp，您可以执行以下操作：

var xmlString = "<lab:labs><lab uri=\"https://thirdpartyhost/api/dept/1\"><name> sample input </name></lab></lab:labs>"
var parser = new HtmlParser();
var parsedXml = parser.Parse(xmlString);
var extractedUri = parsedXml.QuerySelectorAll("lab").Attr("uri").FirstOrDefault();

试试这个：

string xmlString = @"<lab:labs>
    <lab uri=""https://thirdpartyhost//api//dept//1"">
        <name>sample input</name></lab>
    </lab:labs>".Replace("lab:labs>", "labs>");

XmlDocument doc = new XmlDocument();
doc.LoadXml(xmlString);
XmlNodeList nodes = doc.SelectNodes("labs//lab");

if (nodes != null && nodes.Count > 0)
{
    XmlNode node = nodes[0];
    if (node.Attributes["uri"] != null)
    {
        string uri = node.Attributes["uri"].Value.ToString();
    }
}

replace将删除您未使用的命名空间，xmlString是您的responseString。
