Hi folks,
I'm experimenting with scripting the building of a POST message. So,
I'm creating a set of lines that take the form
"<opening_tag_string>" & tVariable & "</closing_tag_string>" and
using a repeat loop to build each component of each lines into a
variable tMessage.
When I use 'add return & "opening–tag–string" & tVariable after
tMessage' to create a partial XML node statement, I get what I would
expect to see in the message box when I put tMessage.
However, when I attempt to 'add return & "opening–tag–string" &
tVariable & "closing_tag_string" after tMessage' to create the full
statement, the opening and closing tag strings disappear and I'm
left with just the list of tVariable in tMessage.
I guess there is some wrapping or encoding that I need to apply to
the tag strings to preserve them inside the variable, but I can't
seem to find anything in the docs or the lists - I'm obviously using
the wrong search terms.
Any clues gratefully received.

There are a limited number of tags that livecode recognizes and thus
allows formatting of fields much like the early web pages.
The message box is simply a field in a stack, and
when debugging HTML and other code/encoded/decoded strings, the
message box is a very poor tool.
Save yourself some headaches and put the text strings into a good text
processor that won't automatically do things like change line endings
from Unix to Windows, etc. I use BBEdit, others use TextWrangler, and
a search of the archives will show others.
Further caution is needed if using UTF8 or uinicode, since character
sets across platforms, servers, and software packages can create hard-
to-detect bugs.
