# strips from the beginning of the string, % from the end. ## and %% are the same when you're removing a literal string, so might as well use % and #. See string operations. Not all shells have all of these. Some don't have any of them. Developers on embedded busybox are more fortunate than some people using 'real' shells, it has at least a few
Code:
VAR="${VAR#<title>}" # Strip out <title>
VAR="${VAR%</title>}" # Then strip out </title>

YOu could also try putting quotes around "${VAR%"</title>"}"

globbing should also work inside it, so:
Code:
VAR="${VAR#<[^>]*>}" # Remove first <...>
VAR="${VAR%<[^>]*>}" # Remove last <...>

Also: If it works in the prompt and not in your script, then your data may not be what you really think it is. You feed it a nice "<title>stuf</title>" and it works but the data actually has stuff after <title> perhaps. PLEASE post a sample of your input data!!
