Question

My C#/.NET application reads XML files that are manually edited by the users. The allowed elements and tags are described in the application’s documentation. I’m using LINQ to extract data from the XML file.

Before extracting data from the XML file, I’d like to validate it to see if it has the expected structure. If not, it would be nice to have information about what is wrong so that I can give some feeback to the user.

What’s the simplest way to do this in C#?

Answer 1

You can validate xml files against XSD.

• First you have to create Xml Schema Definition file. See example
• use XML Schema Definition Tool to create XSD from XMLfile
• Use this code to validate input XML using corresponding XSD

Hope this will help…

EDIT

This article explains all possible ways to validate xml, using C#

IMO best option is to use XSD.
