c# - struggling with XML namespaces (linq)... what am I doing wrong here? -

-

Something trying to parse XML, but apparently it is too much for a lazy Sunday afternoon, / P>

This is my code: (I tried the XPathDocument and XmlDocument approach, but it also failed too badly) 

  XmlDocument xmlDoc = New XmlDocument (); XmlDoc.LoadXml (POSTDATA); XDocument xDoc = XDocument.Load (new XmlNodeReader (xmlDoc)); X-namespace soap = "http://schemas.xmlsoap.org/soap/envelope/"; XElement xEnv = xDoc.Descendants (SOAPON + "envelope"). first (); Excellence xBody = xEnv.Descendants (SOAPOVAN + "BODY"). first (); XReadReply = xBody.Descendants ("ReadReplyReq"). first ();

The last line fails with the exception: there is no element in this collection, however if I change this last line to: 

  XElement xReadReply = xBody.Descendants) .First ();

This gives the first node which is actually the "Ridleyplayerk" node.

Finally, these namespaces are working, it now fails on the first node without a breed ... oh bitter irony; ^)

This is the XML I am trying to parse: 

  & lt; SOAP-ENV: envelope xmlns: SOAP-ENV = "http://schemas.xmlsoap.org/soap/envelope/"> & Lt; Soap-ENV: Header & gt; & Lt; TransactionID xmlns = "http://www.3gpp.org/ftp/Specs/archive/23_series/23.140/schema/REL-5-MM7-1-2" SOAP-ENV: Actor = "" SOAP-ENV: mustUnderstand = "1" & gt; 12345678 & lt; / TransactionId> & Lt; / SOAP-ENV: Header & gt; & Lt; Soap-ENV: Body & gt; & Lt; ReadReplyReq xmlns = "http://www.3gpp.org/ftp/Specs/archive/23_series/23.140/schema/REL-5-MM7-1-2" & gt; & Lt; MMStatus & gt; Read & lt; / MMStatus & gt; & Lt; Timestamp & gt; 2007-12-13T14: 05: 27 + 01: 00 & lt; / Timestamp & gt; & Lt; MessageId & gt; 54321 & lt; / MessageId> & Lt; Sender & gt; & Lt; Shortcode & gt; + 12345 & lt; / Shortcode & gt; & Lt; / Sender & gt; & Lt; Recipients & gt; & Lt; Number & gt; + 12345 & lt; / Number & gt; & Lt; / Recipient & gt; & Lt; Statistic & gt; Message read & lt; / StatusText> & Lt; MM7Version & gt; 5.3.0 & lt; / MM7Version> & Lt; / ReadReplyReq & gt; & Lt; / SOAP-ENV: Body & gt; & Lt; / SOAP-ENV: envelope & gt;

What am I missing here?

And why not XPath just be some more intuitive: "// SOAP-ENV: envelope / soap-ENV: body / readley reek / mmstatus", one of these all instead of crazy hoops To jump through.

I think what you want is to add a namespace manager so that you select XPath on the pre-paid node Can you?

If so, something like this: 

  var doc = new XmlDocument (); Doc.LoadXml (PostData); Var ns = New XmlNamespaceManager (doc.NameTable); Ns.AddNamespace ("SOAP-ENV", "http://schemas.xmlsoap.org/soaf/envelope/"); Ns.AddNamespace ("def", "http://www.3gpp.org/ftp/Specs/archive/23_series/23.140/schema/REL-5-MM7-1-2"); XmlNode list = doc.SelectSingleNode ("// SOAP-ENV: envelope / SOEP-ENV: body / DIF: readley repreive / DIF: MMStatus", ns);

Maybe what you want

asp.net - Javascript/DOM Why is does my form not support submit()? -

This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

sockets - Delphi: TTcpServer, connection reset when reading -

I am trying to implement one for Delphi, but there are some problems with communication. Fitnesse will start my process, and give me a portmember as a command line argument. Then I should make a socket on the port number given to me, and fitness will connect to that port I am using a TCPCP server for the job: < Pre> TcpServer1.LocalPort: = ParamStr (ParamCount); TcpServer1 Active: = true; On OnEXEPT () -Event, I send the protocol version to use as specified in the protocol. Process TForm1.TcpServer1Accept (From: TOBject; ClientSocket: TCustomIpClient); Var s: ansistring; Start clientSocket. Syndrome ('slim - v 0.0', # 10); SetLength (S, 6); ClientSketts Receavebook (S, 6); End; When I call ReceiveBuf (), the process ends, and fitness throws an exception: java.net.SocketException: connection Reset I have seen what sent and received. It shows that my code sends the protocol version, fitness sends back a message, and when I try to get this message

javascript - Classic ASP "ExecuteGlobal" statement acting differently on two servers -

-
I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
