I'm getting the following block of xml back from a web service:
<?xml version="1.0" encoding="utf-16"?>
<ArrayOfItemResponse xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<ItemResponse>
<Item xmlns="http://www.xyz.com/ns/2006/05/01/webservices/abc/def">
<RequestKey Name="ESM.PA" Service="" />
<QoS>
<TimelinessInfo Timeliness="REALTIME" TimeInfo="0" />
<RateInfo Rate="TIME_CONFLATED" TimeInfo="10" />
</QoS>
<Status>
开发者_开发技巧 <StatusMsg>OK</StatusMsg>
<StatusCode>0</StatusCode>
</Status>
<Fields>
<Field DataType="Utf8String" Name="DSPLY_NAME">
<Utf8String>D15 |ASDFDSAA ETF </Utf8String>
</Field>
</Fields>
</Item>
</ItemResponse>
</ArrayOfItemResponse>
I'm trying to capture the Status element in an object as follows, but it's not working.
var _xml = XDocument.Parse(xmlFromService);
var stat = _xml
.Descendants("ArrayOfItemResponse")
.Descendants("ItemResponse")
.Descendants("Item")
.Descendants("Status");
What's the best way for me to get this element?
If you want to use System.Xml.Linq, you can use this expression:
var stat = (from n in _xml.Descendants() where n.Name.LocalName == "Status" select n).ToList();
You are not able to get the required results with your existing code because of the xmlns attribute in Item
<Item xmlns="http://www.xyz.com/ns/2006/05/01/webservices/abc/def">
This question addresses the problem you are actually facing. If you don't know the namespace then you should take a look at this question.
I don't know the best way, but you can read it like this
XmlDocument xdoc = new XmlDocument();
xdoc.Load(stream);
var statMsg = xdoc.GetElementsByTagName("StatusMsg")[0].InnerText;
var statCode = xdoc.GetElementsByTagName("StatusCode")[0].InnerText;
use xpath, something like
var stat = _xml.SelectSingleNode(@"ArrayOfItemResponse/ItemResponse/ItemStatus/StatusCode").Value;
that should put the value 0 into stat.
Your xml code use Namespace.
XNamespace ns = "http://www.xyz.com/ns/2006/05/01/webservices/abc/def";
var stat = _xml.Descendants(ns + "Status");
