Hi All,
I have a script that I convert xml tags to html. like "<" I convert to
"<" and so on.
after the conversion I need to capture the information inside the tag.
let take for example the string "<abcd>: which is equivalent to
show/hide quoted text
"<abcd>".
I tried to capture the "abcd" which can be different from tag to tag
in the following way:
/\<\;([^\&\gt\;]*)/
like match "<" and then match anything that is not ">".
the thing is that it doesn't work on all tags for some reason and I
was wondering on a principal base if doing a [^somestring] suppose to
work ?
Thanks.

No, using [^string] wont work as you're expecting. Just like
[string] doesn't match 'string' but only one of the letters s, t, r,
i, n, or g [^stirng] just matches one letter which isn't in 'string'.
What you need is a negative look-ahead (?!string). Read 'perldoc
perlre' for the explanation of it.

You probably want something like:
/<(.*?)>/

The (?!string) didn't work for some reason but I have learned a lot
from "perldoc perlre" ;)
The solution was /<(.*?)>/ which is the simple one. I tried it
with only (.*) but it was "greedy".
Thanks John and Peter for your quick respone.

I'm still confused with your terminology 'xml tags to html'.
So be it.
show/hide quoted text
How do you go from "<abcd>" to "<abcd>" without capturing
'abcd' ?
