[stringtemplate-interest] Attribute not found exception?

[Miha Valencic]

Terence,

I to would like to know which attributes are needed in a given template.
Either by catching exception messages or by getting  a list of "used"
attributes in the list. I kind of though that Attributes property would
contain those, but found out that this collection is populated after the
SetAttribute method calls.

So, for now, I am using the block pasted below. Is there a better way to
achieve this? (I hope I am missing something :)). Good work though, thanks!
(I am using the C# version)

  Miha.

code to get all the required properties:

            StringTemplate st = new StringTemplate("I like $colour$ colour
and $temperature$ beer.");

            foreach (object o in st.Chunks) {
                if (o.GetType().ToString() == "
Antlr.StringTemplate.Language.ASTExpr") {
                    // do something with the attribute
                    st.SetAttribute(o.ToString().Trim(), "[value]");
                    // or
                    requiredAttributes.Add(o.ToString().Trim());
                }
            }
