I need to validate CSV files in a .NET project. XPATH is used to navigate XML files. We are already using XPATH to validate xml files. Can we navigate a csv file using XPATH to carry out validation ?
You already answered your own question:
XPath is used to navigate XML files.
so: No.
No, you can't XPath works for XML based data only.
You might generate an XML file from your CSV file and validate it, then:

At work, we're modifying an XLSX file, and we would like to turn this modified file into an HTML file (to convert it into PDF using Puppeteer#, but it's not the point here).
We know how to get XML files of this XLSX, and I already found XSLCompiledTransform to convert XML files to HTML.
The annoyance here is that, from what I have read for XSLCompiledTransform, to transform XML file to HTML you need one stylesheet + one XML file.
This brings three problems :
It looks like the stylesheet into XLSX for each sheet isn't well formated to use with this XSLCompiledTransform.
The XLSX file contains multiples sheets, so we would have to fuse them in some manner, and we don't know how.
It is not just some random XML files, they're parts of an XLSX file. Thus there are also some XML files in addition to the sheets (like a workbook and other files) and we can't figure how we could generate an HTML file which is precisely like the XLSX file as open using Excel without using these XML files.
These problems could be resumed as: We struggle to find how to generate an HTML file which will look exactly like the original whole XLSX file.
We don't really want to create an HTML file from some XML files, so any means to transform an XLSX to HTML is good.
We also know that there are some tools and libs available to directly do this, but all the ones I've found aren't free, and we would like to avoid to pay for that as it's the first time we need it and maybe the last.
Does anyone know an accurate option to programmatically transform an XLSX file to HTML, keeping every style options and using C#?
I don't know if this is possible or if I am thinking about this in the wrong way, but this is what I want to do:
I have an XML file linked to an XSLT file and I want to use C# to get the output of the transformed XML file and Response.Write() that wherever I want on the page.
I have found questions on stackoverflow about saving the transformed output to a new file etc, but I don't want to save it to a file, I just want to display it with Response.Write() anywhere on my aspx page.
Is there any way to do this in C#?
Any help is appreciated.
Yes, save the transformed file to a MemoryStream (so in memory not the hard disk). You can then output that to a string using a filestrem reader.
Another way of doing it is by using the XML control, it has XML and XSLT properties.
You could save yourself the effort and simply serve up the XML to the browser. As long as the XML document references the URL of the corresponding XSLT document, the browser will render the page for you.
Use HttpResponse.OutputStream as output stream to save transformed file.

LINQ to XML is one option. See also: Generating HTML using LINQ
The question is a little open-ended, but you might consider just writing a program that:
Deserializes the XML.
Having read in the XML, format the text.
Output the text using the standard in/out libraries in C#.
I don't know if this is the most efficient solution -- but I think it would work.
We would like to read information out of an xsd file in order to create a table with the same structure.
Is the way to do it just opening the file as an xml file, then parsing it, or is there a better way to do it?
XmlSchema.Read Method: http://msdn.microsoft.com/en-us/library/system.xml.schema.xmlschema.read.aspx
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#?
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...

IMO best option is to use XSD.
