Wrap selection in XML element

[adunning]

Most XML editors have a feature to wrap the current selection in an XML element, providing completion to suggest valid tags at that point in a file.

Within VS Code, the built-in 'Emmet: Wrap with Abbreviation' function provides part of this, but it is not XML-aware and does not give a list of the allowed tags in the current context. It would thus be brilliant if the XML extension could provide this.

There are at least two ways to implement this:

1. Inline: TextMate allows the user to make a selection, then type Ctrl + < to insert open/close tags around it, balancing the element name as the user types. The VS Code XML plugin could use this approach to immediately provide a list of options identical to the current functionality when typing <.
2. With a dialogue box: Similar to the existing Emmet function but with autocompletion. The Oxygen XML Editor, for example, provides such a dialogue with the shortcut Ctrl + E. The Scholarly XML extension for VS Code has an implementation of this, but it conflicts with this XML plugin.

Many thanks for your work on this project and considering this request!

@adunning if I understand correctly, teh native emmet extension does the job, but you would like to just have completion for allowed XML tags in command palette, is that?

[adunning]

Yes, exactly: giving users a list of available tags is an enormous help for beginners to a schema and prevents typos for everyone.

I prefer an inline interface along the lines of what the extension already provides, but it's likely a question of what is easier to implement.

Thank you again for your consideration!

I fear it can be a long task, I'm not sure that we will implement that soon. If we see that we hav emore andmore user who want to have this feature, we could change the priority.

@adunning don't hesitate to create any issue that you think it is important for RelaxNG and TEI.

For instance I wonder if xml:id supports could help TEI users (having completion, definitin, validation for xml:id). If you think it is important please create the issue and another. Thanks!

This similar to #605

I just want to add that this has been implemented both by the Scholarly XML (mentioned above) as well by TEI Publisher Extension for Visual Studio Code, but neither of them has the completion feature.

Ok thanks @otichy for your feedback. I will see if it is easy to implement.

@adunning @otichy I have started to implement inline wrap element at #813 (comment) but it requires to do some more work.
