Validating xml in visual studio

07 Feb

Hello there, we are writing a VSCode extension for Telerik Native Script projects and one of the biggest requirements from our customers is to enable Intellisense for the UI declarations which are written in XML files.

We have a schema declared on the root Page element, but it seems to be ignored at the moment.

For the latest documentation on Visual Studio 2017, see Visual Studio 2017 Documentation.

For the latest documentation on Visual Studio 2017, see XML Document Validation on docs.

You then perform the validation during the reading and parsing operations of the factory-created Xml Reader object. Validation is the process of enforcing rules on the XML content either through an XSD schema or a DTD or XDR schema.

Let's review some XML basics before diving into how the new features in XML can help you validate XML data more easily. An XML document contains elements, attributes, and values of primitive data types.

Is this something that is supposed to work, or are we missing something.

Here is a sample of an XML file (taken from our repo - Script/template-hello-world): @egamma By the way, the autocomplete-plus package provide is exactly what we need. As far as I found, the API is not rich enough, but I hope I might've been mistaken...

Now that the schema is loaded, Visual Studio will automatically suggest elements and attributes to insert.

XML data is valid when the elements and the content of the individual elements in the XML data conform to the declared data types specified in the schema or DTD. NET is handled primarily by the classes present in a handful of namespaces: System. The classes that are commonly employed to validate the XML document are Xml Reader, Xml Reader Settings, Xml Schema Set, and Xml Node Reader.

Xml namespace is probably the most significant of these namespaces if only because it includes classes such as Xml Document, Xml Node Reader, Xml Reader, and Xml Reader Settings, which are critical in validating XML data.

Yes, perhaps the initiative to support the XAML/XML -like csproj in core could be much less painful if we had more interactive development of the .csproj file.

I had been looking at venturing to build this, something that crossed REST client to api.nuget and used XML schema to create a very smooth yeoman-like experience, but with intellisense on available attributes and applicable versions of a package.
