Shiesse.
The docs all just show it as:
(Expression,[i,g,m])

The g needs to be in quotes for the global flag.
This works for me:
text_item = "fred was here";
my_exp = new RegExp("fred",'g');
new_string = text_item.replace(my_exp, "dave");
debug(new_string);

More likely PEBKAC.
"Problem Exists Between Keyboard And Chair"
text_item = "fred was here";
my_exp = new RegExp("fred",g);
new_string = text_item.replace(my_exp, "dave");
Nothing happens, or in some variations I get "Null" in
the debug trace.

I am a great fan of the
saying ‘if you have a problem that is best solved by regular expressions, then
you have two problems’.
What were you trying to do
again?

I tried a whole whack of variations and could not come up with a combination to
get it to work. :-/
The docs at the authors homepage had no sample code snippets, and the example
.fla code of course would not transfer.
The OP never did say how he resolved, so I just dropped it.

In Xerte the replace method
is added to the String class, so it’s
myString.replace(myRegExp,
‘replaceString’);

I could be imagining things, but I thought Julian just posted something about
Regular Expressions now being supported.
If that is true, then this would work:
new_xml = replace(original_xml, /the_string_here/g, "");
the /g at the end if the string parameter means "global", so it would
replace all the instances of that URL with "".

Cheers Dave that's very helpful - I'll give
that a try.

XML shorthands the closing tag to save characters when all the info is
contained in the attributes, i.e. there is no actual value between the tags.

<link type="text/html" rel="alternate" href="http://twitter.com/jamesclay/statuses/1483252089"/>
//all data in opening tag attributes, no explicit closing tag, just />
So if you know the format you show below would be consistent, you could key on
that "/>" as the end of the string and RFind (reverse find) back
to the first "/" you hit.
That should isolate the actual picture name/format.

Hi all
I've been experimenting with the
new module method of creating templates and have created a couple of new templates
optimised for a specific purpose which I’ll happily share with the community
once complete. One is an optimised view of twitter feeds but unless I’m
mistaken it seems like the xml isn't complete for some reason. I can pick up
and display the text and links etc ok but I can't work out how to access the
profile pics. Here's an example entry...
<entry>
<id>tag:search.twitter.com,2005:1483252089</id>
<published>2009-04-09T12:59:26Z</published>
<link
type="text/html" rel="alternate" href="http://twitter.com/jamesclay/statuses/1483252089"/>
<title>@ronm123 I meant in a browser, via a second projector
probably.</title>
<content
type="html"><a href="http://twitter.com/ronm123">@ronm123</a>

<updated>2009-04-09T12:59:26Z</updated>
<link
type="image/png" rel="image" href="http://s3.amazonaws.com/twitter_production/profile_images/96243182/Photo14_normal.jpg"/>
<twitter:source><a href="http://twitter.com/">web</a></twitter:source>
<author>
<name>jamesclay (James Clay)</name>
<uri>http://twitter.com/jamesclay</uri>
</author>
</entry>
I want to be able to strip out the
path to the .jpg e.g.http://s3.amazonaws.com/twitter_production/profile_images/96243182/Photo14_normal.jpg
But can't work out how to do
that. I can access the content of <id>,<title> and even
<name> but the tag containing the profile pic link e.g. <link
type=”image/png” doesn’t have a closing tag. Presumably I need some kind of
function + regular expression - any suggestions?
Cheers
Ron
