How to efficiently decode XML encoded string from Span<char>

[lsoft]

Hi!

I have a XML encoded string in Span<char>, and I need to get decoded string. I have the following solution now:

var mystring = @"my string !@#$%^&*()_+|-=\';[]{},./<>?".AsSpan();
string result = global::System.Net.WebUtility.HtmlDecode(mystring.ToString());
return result;

I would to get rid of ToString for intermediate string, but I failed to find such alternative in .NET. Any approaches or ideas, guys?

Thanks!

There isn't span related API for xml yet. Xml was not focused for optimization in these years.

@huoyaoyuan thanks for info. I am wondering: will it be helpful for tracking purposes to convert this discussion into the issue?

I think it's better to open a new issue, and specify the API and scope you want to get improved.
