Validate Xml file

Question

Hello,

I just need to verify if a file is xml, no specific structure, so just loading to an xml parser and if no exception is thrown at load, I'm fine with it, so I use:

Dim doc As XDocument
doc = XDocument.Load(InputStream, LoadOptions.None)
Check for exceptions
doc = Nothing

Now, is it the same as using the below code?

Dim doc As New XmlDocument
doc.Load(InputStream)
Check for exceptions
doc = Nothing

Any difference in loading behaviors of XDocument vs XmlDocument?

Thanks :)

Hi @StewartBW ,

For the specific task of verifying if a file is XML by attempting to load it and catching exceptions, both XDocument and XmlDocument will achieve the same result.

But XDocument provides options like LoadOptions to control certain behaviors (e.g., preserving white space, setting base URI, etc.).

Best Regards.
