Xml validation

Xml validation

• ofsarac

  It does validate. I've just run the code from the sample on device (adjusted for paths and luck of console). Sure enough it shows expected message about attribute. Here’s my code (add two buttons and a textbox to the form, also add XML and XSD files to your project, set action to “Content” and condition to “Deploy always”):

  using System;

  using System.Collections.Generic;

  using System.ComponentModel;

  using System.Data;

  using System.Drawing;

  using System.Text;

  using System.Windows.Forms;

  using System.Xml;

  using System.Xml.Schema;

  using System.IO;

  using System.Reflection;

  namespace ValidateXml

  {

  public partial class Form1 : Form

  {

  public Form1()

  {

  InitializeComponent();

  }

  private void button2_Click(object sender, EventArgs e)

  {

  this.Close();

  }

  private void button1_Click(object sender, EventArgs e)

  {

  string path = Path.GetDirectoryName(Assembly.GetExecutingAssembly().GetName().CodeBase);

  // Create and load the XML document.

  XmlDocument doc = new XmlDocument();

  doc.Load(Path.Combine(path, "booksSchema.xml"));

  // Make changes to the document.

  XmlElement book = (XmlElement) doc.DocumentElement.FirstChild;

  book.SetAttribute("publisher", "Worldwide Publishing");

  // Create an XmlNodeReader using the XML document.

  XmlNodeReader nodeReader = new XmlNodeReader(doc);

  // Set the validation settings on the XmlReaderSettings object.

  XmlReaderSettings settings = new XmlReaderSettings();

  settings.ValidationType = ValidationType.Schema;

  settings.Schemas.Add("urn:bookstore-schema", Path.Combine(path, "books.xsd"));

  settings.ValidationEventHandler += new ValidationEventHandler (ValidationCallBack);

  // Create a validating reader that wraps the XmlNodeReader object.

  XmlReader reader = XmlReader.Create(nodeReader, settings);

  // Parse the XML file.

  while (reader.Read());

  }

  // Display any validation errors.

  private void ValidationCallBack(object sender, ValidationEventArgs e)

  {

  this.textBox1.Text = String.Format("Validation Error: {0}", e.Message);

  }

  }

  }

  Hi thanks for your help. I only copied the file in the same directory of the exe. I tried to launch this example before local to my computer (by double clicking on the .exe). And it doesn't give any error.
  
  When I try to deploy it on the device it doesn't found the file but they are in the same folder...
  
  Please help :)

  Sure. VS comes with a great help system which is accessible via F1 button. Just hit F1, type “File properties” and you’ll find them in no time.

  I created this example as a Windows application and it works. The same example as a Pocket PC 2003 application CF2.0 doesn't validate. So...

  It could not possibly display any errors as PPC 2003 has no console. Change the code to pop up a message box or set a breakpoint in debugger.< xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

   

  Device has no support for relative paths so putting files to the EXE folder won’t do you any good. Full path has to be specified or files won't be found.

   

  One more thing: for some reasons many developers believe device can see desktop’s hard drive by simply specifying “C:\path\file”.

  That is of course not the case – device can’t see desktop’s hard drive. So please make sure files are on device file system.

  Wonderful so it could be a deployment error. Very thanks!!!
  
  

• Latso

  Very thanks. Looking at the doc I believe this rule are contained in the assembly is correct
  
  Ok another thing. This strategy to use XML for configuration of my app (Tomcat like) is the more appropriate Or .NET gives me some additional instrument to use
  
  Sorry for the diozen of requests but I came from Java :)
  
  Hi

  If you mean validation against schema, validating XML reader is available on NETCF V2 and it works the same way as on desktop. There's no way to validate XML on NETCF V1 unless you do it all yourself.

  
  
  

• GregRoy

  That's properties of files in VS project which are telling VS what to do with the file and when to do it. It's not device specific.

  If you copied it without any modifications (really you have to at least correct file paths), the output goes to console. Does your device have console If not, you won't see any output.

  Thank you but the problem is that CF don't validate XML against a Schema. Anyway I've installed a prompt on my Ipaq.
  
  Thanks for the tips :)
  
  Hi
  
  

• VladAll

  Another thing. Where are the options: setAction & condition and what is their role
  
  Hi & thanks
  
  

• Charley Lou

  Thanks but I cannot find where to set that options can you explain me a where I can found it.
  
  Thanks
  
  

• Jonathan Sampson

  Yeah but to me it doesn't work. I tried this simple example: http://msdn2.microsoft.com/en-us/library/56xykaw6.aspx but it terminates correctly without raising any validation error. I copied the files without any modification but it doesn't work.
  
  Someone has never tried to effective trying to validate an XML against a schema in CF Any suggestion
  
  Thank you
