selectsinglenode

Taking this simplifed example of my XML: <?xml version="1.0"?> <message xmlns="http://www.mydomain.com/MyDataFeed" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.mydomain.com/MyDataFeed https://secure.mydomain/MyDataFeed/myDataFeed.xsd" requestId="13898" status="1"> <error>Invalid Login</error> </message> I am trying to select the 'error' node using SelectSingleNode method, however using the following code it always returns NULL? XmlNode errorNode = oss.SelectSingleNode("/message/error"); if (errorNode != null) Console.Writeline("There is an error"); From

My XML looks like : <?xml version=\"1.0\"?> <itemSet> <Item>one</Item> <Item>two</Item> <Item>three</Item> .....maybe more Items here. </itemSet> Some of the individual Item may or may not be present. Say I want to retrieve the element <Item> two </Item> if it's present. I've tried the following XPaths (in C#). XMLNode node = myXMLdoc.SelectSingleNode("/itemSet[Item='two']") --- If Item two is present, then it returns me only the first element one . Maybe this query just points to the first element in itemSet, if it has an Item of value two somewhere as a child. Is this interpretation correct?

I am getting this error with SelectSingleNode method: DNX Core 5.0 error CS1061: 'XmlDocument' does not contain a definition for 'SelectSingleNode' and no extension method 'SelectSingleNode' accepting a first argument of type 'XmlDocument' could be found (are you missing a using directive or an assembly reference?) Is it not supported yet? What are my alternatives? In .Net Core 1.0 and .Net Standard 1.3 SelectSingleNode is an extenstion method https://github.com/dotnet/corefx/issues/17349 Add a reference to make it available again: <PackageReference Include="System.Xml.XPath.XmlDocument"

I've come up kinda dry as to why -- at least in the .Net Framework -- it is necessary to use an XmlNamespaceManager in order to handle namespaces (or the rather clunky and verbose [local-name()=... XPath predicate/function/whatever) when performing XPath queries. I do understand why namespaces are necessary or at least beneficial, but why is it so complex? In order to query a simple XML Document (no namespaces)... <?xml version="1.0" encoding="ISO-8859-1"?> <rootNode> <nodeName>Some Text Here</nodeName> </rootNode> ...one can use something like doc.SelectSingleNode("//nodeName") (which would

Hi I have xml file (which is actually msbuild file) that uses different namespace <?xml version="1.0" ?> <Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <PropertyGroup Condition="'$(key)'=='1111'"> <Key>Value</Key> </PropertyGroup> </Project> But the problem is I can't use SelectSingleNode with that file because of xmlns="http://schemas.microsoft.com/developer/msbuild/2003" I believe it's since default namespace (necessary for the method) is gone because of xmlns above. Then I think I just need to add necessary one for that.. But my tries weren't

Okay, so here is the snippet of my web.config file: <?xml version="1.0" encoding="utf-8"?> <configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0"> <location path="." inheritInChildApplications="false"> <connectionStrings> ... </connectionStrings> </location> <location path="." inheritInChildApplications="false"> <appSettings> <!--IT Ops--> <add key="SomeOtherKey" value="SomeOtherValue" /> <add key="SiteDomain" value="somedomain.com" /> <add key="SomeOtherKey" value="SomeOtherValue" /> .... </appSettings> </location> </configuration> What I'm trying to do is find the node
