.removing empty elements

Hi,

I've written data from a dataset to xml with ds.WriteXml.
The problem is that empty fields in a record are written as empty elements in the xml-file.
Example
<fax>
<mobiel>
<email>
The best option is to avoid these empty elements directly at the WriteXml-method of the dataset.

The second option is to read the xml-file after construction, remove al the empty elements from it and save.

After searching the web i couldn't find any suitable solution for this problem. Can someone help me?
Note that the xml-file contains nested elements. Some of the nested elements can be empty also.

thanks

Ruud

Indeed, only the elements who have content need to be written from the dataset to xml.

Otherwise, a solution who will remove all the empty elements from the output xml-file would be a good alternative.

Every solution is right.

XSD:TIME and .NET

(i'm reposting, first time i posted i wasn't logged in Frown | :(

)

hello

i have an xsd with a tag from type "xsd:time". <REGTIME>
when i generate a sample xml file with XML spy i get this sample filled in: <REGTIME>14:20:0Z</REGTIME>
now when i try to parse this file with the .NET xpathdocument the application crashes on this line:

XPathDocument document = new XPathDocument(readerToUse);
(readerToUse is of type xmlreader)

it crashes and says this string in REGTIME is not a valid string for type DATETIME.

so i assume .NET recognizes the xsd:time field, but says it's invalid, why? xmlspy says it's ok.

i hope someone can help me out here.

thank you

27-Aug-05 3:07

I'm trying to use MSXML 4 DOM to parse a xml document in Visual C++, but without success. A snippet of the xml structure is a following:

<data>
<album label="Album title 1">
<track label="Label 1" sndUrl="1\0.jk" txtUrl="1\0.jk"/>
<track label="Label 2" sndUrl="1\1.jk" txtUrl="1\0.jk"/>
</album>
<album label="Album title 2">
<track label="Label 1" sndUrl="2\0.jk" txtUrl="2\0.jk"/>
<track label="Label 2" sndUrl="2\1.jk" txtUrl="2\0.jk"/>
</album>
</data>

Can anyone give me a code snippet to parse album label, track label, sndUrl, txtUrl attributes to a CString?
Please help!
Thanks in advance for any answers.

Problem loading XML

26-Aug-05 3:55

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

A very simple problem with XML

26-Aug-05 2:34

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() ) // read XML node by node
{
  if( doc.Name == "Lname" && doc.Value == Lname )
  {
    doc.Read(); // read following node (Fname node)
    return doc.Value; // return its 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 Blush | :O

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. Blush | :O

Of course Read() is method of XmlReader.

Parse XML to memory from a string

25-Aug-05 1:25

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 ZiggY,
that depends on tools you use. In .NET, it's XmlDocument.LoadXml( xmlString ).

can any one suggest a solution to it or any workaround.

XML Serialization private field problem

scchan198422-Aug-05 15:51

scchan1984

22-Aug-05 15:51

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
{
	/// <summary>
	/// Summary description for IWheel.
	/// </summary>
	public interface IWheel
	{
		string GetWheelType();
		void SetWheelType(string type);
	}
}

Thanks

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?

sample xml from xsd

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.
