Hi all,
I've produced a string concatenator for a specific purpose, but it has a
bug.
http://myweb.tiscali.co.uk/ladycroft/Rewrite_line_in_text_file_based_on_contents.html

It's functional in firefox and chrome but in IE an extra newline (wrap)
appears in the output causing a problem. ...

any ideas on how to catch and kill this bug?

cheers.

Does this do the trick?

var input ="My-Video.wmv\nMy-Video2.wmv\n";
var reLine = /^([-\w]+)(\.\w+)$/m;
var output = input.replace(reLine,"<li><a onclick=
\"play(this.href);return false\" href=\"$1$2\">$1</a></li>");

clever stuff! .. That regex is alien to me ;)
It does work the same in firefox and IE ... but so far I only have it
returning one line for the first list item, and the unchanged remaining list
items.

what is that $1$2 stuff? looks like perl variables..
How does it 'know' those are the names in the list?

and how can I have it process all the list items?

I guess understanding your regex would explain all ..
know of a good online resource?

Add the global flag to the regexp :/^([-\w]+)(\.\w+)$/mg
^

Thats references to the two matched groups, grouped by the parentices ()

Not sure what you mean

See above

A good tip is to actually try to find the information your self before
asking others about it. Hint: google it.

Thanks, got it working now ..
Of course my first recourse was to web search for stuff on regex, but
everyone in the world has a favourite resource on regex right?

One of the things I have learned here is that regex can simplify/save many
lines of code in specific cases. .. I just gotta learn to use it.
Thanks again.
