Hi
I am trying to upload the XML file to parse it. While I upload it I am getting this error:
System.Xml.XmlException: The '0' character, hexadecimal value 0x30, cannot begin with a name. Line 726, position 2823.
Somwtimes I also get invalid character exception.
I am parsing many XML files in a "for loop" after downloading it from a website automatically. Is their anyway to ignore these exceptions and able to load the document or a way to solve this problem with XML files through a progam, so that I dont have to manually handle such characters in the file?
Any help would be appreciated.
Thanks

Hi, I am new to manipulating XML with C#.
I want to know how to retrieve an element value.
I have this vey simple XML file :
<?xml version="1.0" encoding="utf-8"?>
<people>
<person>
<Lname> Washington </Lname>
<FName> George </Fname>
</person>
<person>
<Lname> Lincoln </Lname>
<Fname> Abraham </Fname>
</person>
</people>
All I need is a simple method :
public string GetFname(string Lname)
{
...
}
which returns the first name by last name.
Thanks a lot!

hi,
There are some different ways how you can do that. Maybe easiest (but not necessary most effective) is this:
XmlDocument doc = new XmlDocument();
doc.Load( fileNameofYourXml )
while( doc.Read() )
{
if( doc.Name == "Lname" && doc.Value == Lname )
{
doc.Read();
return doc.Value;
}
}
OR you can go with XPath:
doc.SelectSingleNode( string.Format("/person/following-sibling::Lname='{0}'", Lname) );
But I bet I got syntax for that XPath expresion wrong

Hi, thanks for your reply,
In fact I tried the first method. It doesn't work.
1-XmlDocument has no method Read, (only a method ReadNode which take a reader as argument! No idea how it works)
2-Instead I used XmlTextReader, still not working. One remark: when I display all the Values and Names in a label, I get many of them null. Other think, they are always the same : value=name?
Any hint?
For the Xpath method didn't try it.
Thanks.

Oh yes, sorry. My bad. Of course Read() is method of XmlReader.

Can you post snippet of your code?

Hi, since it is a simple requirement, I have placed a simple solution
Try this..
//////////////////////////////////////////
using System;
using System.Xml;
namespace ConsoleApplication1
{
/* c:\pk.xml
<people>
<person>
<lname> Washington
<fname> George
<person>
<lname> Lincoln
<fname> Abraham
*/
class XmlTest
{
XmlDocument doc;//
public XmlTest()
{
doc = new XmlDocument();
doc.Load("c:\\pk.xml"); // put your file path
}
public void Run()
{
while(true)
{
Console.Write("\nEnter a Name: ");
string input = Console.ReadLine();
if(input == "" || input==null)
break;
Console.WriteLine("Your FName is " + GetFName(input));
}
}
public string GetFName(string lname)
{
string ret = "Unknown" ;
XmlNodeList lnode = doc.GetElementsByTagName("Lname");
for(int i=0; i< lnode.Count; i++)
{
if(lnode.Item(i).InnerText.Trim() == lname.Trim())
{
ret = lnode.Item(i).ParentNode.LastChild.InnerText;
break;
}
}
return ret;
}
public static void Main()
{
XmlTest xmlDoc = new XmlTest();
xmlDoc.Run();
}
}
}

How do we parse a xml data in a string to memory (without saving it as a file ...etc.)?
In my form, i am submitting an xml file's text in a hidden field. I want to receive it as a string, and directly parse it to memory and perform DOM functions on it...

Hi
I am using WSE 2.0 to sign and encrypt a soap message using the x509 xcertificate. The problem is when I only sign the message it works fine but once I use encryption it gives me following error:
---------------------------------------------------------------
Microsoft.Web.Services2.Security.SecurityFault: Referenced security token could not be retrieved
at Microsoft.Web.Services2.Security.EncryptedKey.LoadXml(XmlElement element)
at Microsoft.Web.Services2.Security.EncryptedKey..ctor(XmlElement element)
at Microsoft.Web.Services2.Security.Security.LoadXml(XmlElement element)
at Microsoft.Web.Services2.Security.SecurityInputFilter.ProcessMessage(SoapEnvelope envelope)
at Microsoft.Web.Services2.Pipeline.ProcessInputMessage(SoapEnvelope envelope)
at Microsoft.Web.Services2.WebServicesExtension.BeforeDeserializeServer(SoapServerMessage message)
---------------------------------------------------------------
can any one suggest a solution to it or any workaround.
Thanks.

Hi,
I know that the XML Serializer does not support serializing private field. So I use a public field to get/set the private field like this:
namespace TestObjectToXML.CarComponent
{
[XmlRootAttribute("Wheel", Namespace="", IsNullable=false)]
public class Wheel : IWheel
{
public string wheelSize;
private string _wheelType;
public Wheel()
{
}
public string wheelType
{
get{return this._wheelType;}
set{this._wheelType = value;}
}
public string GetWheelType()
{
return this._wheelType;
}
public void SetWheelType(string type)
{
this._wheelType = type;
}
}
}
However, if the wheel class needs to implement methods from a IWheel interface which has already some get and set method for the wheelType, is there any way to simplify this? Sometimes the interface cannot be modified and has a lot of such get and set methods.
namespace TestObjectToXML.CarComponent
{
public interface IWheel
{
string GetWheelType();
void SetWheelType(string type);
}
}
Thanks

hi,
I have created a webservice project and i have another project of regular type.I have to move the webservice to this regular project.In order to do that what all files should I move and what steps need to be performed.
Thanks in advance,

hi,
umm what do you mean "move the webservice to this regular project"? Sounds like bad design to me... maybe you could move the code to another project (class library) and reference it in your project ( and in webservice project if you will still use it). BTW what is "regular type"? Windows app or class library or.. ?
To answer your question though, all code is in file(s) with extention .asmx.cs (or maybe .asmx.vb). Only difference between web method and ordinary method is in atributes, so without them (I think) it is ordinary method like in any other project.
[edit]can't you just reference dll in /bin folder of your webservice in your project?[/edit]
Does it help?

Hi
has somebody an idea, a hint, a link, to find out, how to
PROGRAMATICALLY generate a sample xml file from
a xsd schema, like it is possible e.g. with XMLSpy?
I have to do this in the code (C#) for schema fragments.
What about:
- .NET xml/xsd API?
- xslt?
Thank you.

An xsd specifies what is a valid document, as you know. This includes specifying a minimum and maximum number of times a node can exist, which means that there are many possible valid documents. The other trick is that XSDs can reference other XSD's, and define types for groups of nodes. I'd be far more inclined to try and unwind this in code than in an XSLT.

I tried the sample code from MS
http://support.microsoft.com/default.aspx?scid=kb;en-us;312114
I got the error message at
chatcenter.Submission += new SubmissionEventHandler(callback.SubmissionCallback);
Type System.DelegateSerializationHolder and the types derived from it (such as System.DelegateSerializationHolder) are not permitted to be deserialized at this security level.
it seems the delegate will not pass security check in remote object.
Does any body know why?
I am using .NET 2003 Enterprise version
Thank You

For example the "<month>" and "<sep>", how can I escape those in the xml?
