I am trying to implement a C# Windows Forms application to generate XML file from a CSV based on XML's schema. I want to do this as much generic as possible since I am going to transform more than 1000 csv/schemas. Any ideas would be appreciated.
There is a pretty good article exposing appropriate approach for this case
converting csv to xml with an xsd

I'm trying to generate an XML file for a dataset across several SQL Server tables. I have an XSD definition for the desired dataset and was wondering if it's possible to use C#'s data objects to point to the tables, note their relationships, extract the data and populate an XML file going via the XSD validate. I'm fine with setting up the tables to EXACTLY represent the hierarchies in the final XML file if this helps.
Many thanks for any help.
You might try the following:
1) Create C# class files from the XSD using the xsd.exe tool.
2) Use an ORM to map the database objects to your C# classes.
3) Use the XmlSerializer class to convert C# objects to an XML document which will match your XSD.

I have a C# WPF program that needs to display GridView and 2D graph data which initially will come from a hardware device. I also want to continuously (or frequently periodic) backup this data to an XML file on disk. What would be the easiest way to implement this in visual studio? Should I create an XML schema first, or use the dataset designer? Should I bother with datasets at all or would it make sense to eliminate them and write my incoming data directly to xml?
I would recommend:
Plan a structure of an XML ahead. Create a simple empty file to help you along the way.
Create a data serialization provider as well as the interface that it will implement. In your case it will be an XML provider (who knows, you may need to save the data to a database in future. You should plan ahead for that.)
Write a custom class that serializes your poco domain objects into an xml using LinqToXML.
We have a need to save some of our configuration items into files. I have been told this is for some localization features we are going to use. From what I have been told, it is much faster to read from a binary file than a straight XML file. Is this true, and is it ideal to save xml data in binary format or is there another way I should save the data to pull it into my web application?
I would like to be able to read the data using LINQ or casting it as an object. Also, what is the best way to parse the file for sepecific data? Any suggestions would be greatly appreciated?
I would recommend using XML over binary simply because it's easier to work with. Binary is faster but I doubt you would notice that speed gain in your application, especially if you cache the values you read from the file.
The easiest way to parse the XML file would be to deserialize it to an object using the XmlSerializer class. This is absolutely the most painless way to parse XML in my opinion.
HI,
I want to keep the Outlook contacts in an XML file. And I want to compare, merge and resolve conflicts of this XML file with another XML file which may have same attributes ?
Also I want to know when a particular node is editied/newly added ? How we can achieve this in XML using C# 3.5 ? Should I use any XML Schemas ? How this is possible ?
Also please let me know using which one is faster - a XML file or a SQLite ?
You can use LINQ to XML, there are various books on LINQ to XML, please refer them.
for small data XML should be fast and effective way to go like configuration data, etc.
for large data SQLite is the way to go.
I have a web application that generates a medium sized XML dataset to be consumed by a third party.
I thought it would be a good idea to provide some form of schema document for the XML that I generate so I pasted the XML into Visual Studio and got it to generate an XSD.
The annoying thing is that my XML doesn't validate to the XSD that was generated!
Is it better to roll your own XSD?
What about different schema docs like DTDs, Relax NG, or Schematron?
The key is that I would like to be able to validate my document using C#.
What are your XML validation strategies?
Whether you choose XSD and/or Schematron depends on what you are trying to validate. XSD is probably the most common validation strategy, but there are limits on what it can validate. If all you want to do is ensure that the right type of data is in each field, XSD should work for you. If you need to assert, for example, that the value of the <small> element is less than the value of the <big> element, or even more complex business rules involving multiple fields, you probably want Schematron or a hybrid approach.
You will be able to validate your XML with either an XML Schema or a DTD using C#. DTDs are older standards as compared to XML Schemas.
So, I recommend an XML Schema approach.
