[REBOL] why this not work? Re:

First, your message format.
Could you please sent your emails to this list in plain text? The HTML of
outlook will probably annoy all the plain text readers of the list.
To do this in Outlook Express you can either:
1) Send all your email in plain text by Tools -> Options -> Send tab and
select Mail Sending Format = Plain Text.
Or
2) For plain text only to this list. Add [list--rebol--com] as an address to
your address book. Select the properies of the this address and choose the
name tag. Check the "Send e-mail using plain text only" checkbox.
Thanks.
Secondly your program.
Your program is self-modifying (though you would not have intended that).
The problem line is
if find in_file "<BODY>" [body_tobe: {<BODY>}]
On this line the word body_tobe is referring to a string that is actually
part of your function definition. I know this sound strange but have a look
at this web page for a simpler explanation.

Change the line to read like this
if find in_file "<BODY>" [body_tobe: copy {<BODY>}]
There are other lines which are affected by this. Use
source make_generic_html_locator
to see the other changes.
On a side note, the line
in_file: make string! in_file
is completely redundant since the result of the read is a string.
Hope it helps.
Brett.

i just cant keep figuring out when you use this with two different files and
go say:
function <file here>
function <second file here>
function <file here>
btw: these are html files with one body having BGCOLOR="white" and one
simply having <BODY>
----- start of function -----
make_generic_html_locator: func [
a [file!] "Filename to add location reference for"
]
[
page_content: "sd"
clear page_content
if not exists? a [print reform ["File not found:" a] halt]
in_file: read a
in_file: make string! in_file
if not find in_file "<HTML>" [print "File is not HTML Compliant"
halt]
if find in_file "<TITLE>" [
parse in_file [thru {<TITLE>} copy page_title to {</TITLE>}]
print page_title
]
parse in_file [thru {<BODY} copy body_attrib to {>}]
body_tobe: rejoin [{<BODY} body_attrib {>}]
if find in_file "<BODY>" [body_tobe: {<BODY>}]
parse in_file [thru body_tobe copy page_content to {</HTML>}]
print body_tobe
print page_content
clear page_content
clear body_tobe
print "Generic Page Locator Finished"
]
