[REBOL] Re: Working with tags

From: brett:codeconscious at: 11-Nov-2003 12:28

An oldie but a goodie :-) A Tag! is a type of String! just written differently. Ie instead of "tag" you write <tag> Rejoin uses Append See what happens when you append to a tag:
>> append <body> { bgcolor="green"}
== <body bgcolor="green"> That's they "why" of it. The how of it...What you wanted was a string result. One approach: text: "This is text" reform [<tag> text <tag>] Another (different result): rejoin [{} <tag> text <tag>] The second one works because the second, third and fourth items in the block are appended to the string giving the right datatype. Compare with: rejoin [[] <tag> text <tag>] ...which you wouldn't use (reduce would be simpler). Regards, Brett.
