Edited:
I'm trying to accomplish three things here: get XmlNode Query, get the XmlNode QueryId and get the value of a:schemaLocation but the after parsing they end up as null. If I remove the qualified name from the XML, the C# bit works fine. How should I re-write my code?
XML:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:loc="localhost">
<soapenv:Header/>
<soapenv:Body>
<loc:Service>
<!--Optional:-->
<loc:input>?</loc:input>
<Query a:schemaLocation="http://www.xyz.com/xml.xsd" xmlns:payload="http://www.xyz.com" xmlns:a="http://www.w3.org/2001/XMLSchema-instance" xmlns="loc4">
<QueryId>Data</QueryId>
</Query>
</loc:Service>
</soapenv:Body>
</soapenv:Envelope>
C#:
private NamespaceManager nsmgr;
private XmlDocument doc = new XmlDocument();
private Stream receiveStream = new Stream(HttpContext.Current.Request.InputStream);
private XmlNode Query, QueryId;
using (this.receiveStream){
using (StreamReader readStream = new StreamReader(this.receiveStream, Encoding.UTF8)){
doc.Load(readStream);
this.nsmgr = new XmlNamespaceManager(this.doc.NameTable);
this.nsmgr.AddNamespace("soapenv", "http://schemas.xmlsoap.org/soap/envelope/");
this.nsmgr.AddNamespace("loc", "http://localhost");
this.nsmgr.AddNamespace("schemaLocation", "http://www.xyz.com/xml.xsd");
this.nsmgr.AddNamespace("payload", "http://www.xyz.com");
this.nsmgr.AddNamespace("a", "http://www.w3.org/2001/XMLSchema-instance");
this.nsmgr.AddNamespace("x", this.doc.DocumentElement.NamespaceURI);
this.Query = doc.SelectSingleNode("//x:Query", this.nsmgr);
this.QueryId= doc.SelectSingleNode("//x:QueryId", this.nsmgr);
}
}
Here you go...
XmlDocument xDoc = new XmlDocument();
xDoc.Load("Query.xml");
XmlNamespaceManager xnm = new XmlNamespaceManager(xDoc.NameTable);
xnm.AddNamespace("schemaLocation", "loc");
xnm.AddNamespace("payload", "loc2");
xnm.AddNamespace("a", "http://www.w3.org/2001/XMLSchema-instance");
xnm.AddNamespace("x", xDoc.DocumentElement.NamespaceURI);
Inner Text For Query:
xDoc.SelectNodes("//x:Query", xnm)[0].InnerText
Inner Text For QueryId:
xDoc.SelectNodes("//x:QueryId", xnm)[0].InnerText
a:schemaLocation Attribute:
string namespaceURI = xnm.GetNamespacesInScope(XmlNamespaceScope.Local).FirstOrDefault(el => string.Equals(el.Key, "a")).Value;
var x = xDoc.DocumentElement.Attributes["schemaLocation", namespaceURI].Value;
Here's a simple solution I came up with:
Removed the following lines:
this.nsmgr.AddNamespace("soapenv", "http://schemas.xmlsoap.org/soap/envelope/");
this.nsmgr.AddNamespace("loc", "http://localhost");
this.nsmgr.AddNamespace("schemaLocation", "http://www.xyz.com/xml.xsd");
this.nsmgr.AddNamespace("payload", "http://www.xyz.com");
Modified:
this.nsmgr.AddNamespace("x", "loc4");
Finding the value of a:schemaLocation worked as suggested by Prash.
