html/template: escape first char for XML

[alexandrestein]

It looks like HTML template escape characters out of the variable.
In my case I tried to build a simple XML file, and the the first charset is escaped.

It looks like a bug to me.

Best regards.

Probably because this is the HTML templating package and you're trying to produce XML. I suspect that it doesn't know how to parse the <?foo> directives with the question mark there.

You probably want to use the text/template package instead, if you're not going to be taking advantage of any of the HTML auto-escaping features.

/cc @robpike @adg to decide what (if anything) to do here.

I made it with encoding/xml package but the behavior is not as expected.

I believe Brad answered the question. Use text/template not html/template, and escape manually.

Ok, but it's a bug.
That's it.
