[Xerte] how to strip out a specific string?

Fri Apr 17 13:48:30 BST 2009

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.

It actually does have a closing tag: />

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.

<name>jamesclay (James Clay)</name> //no attributes,
data between 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">&lt;a href="http://twitter.com/ronm123"&gt;@ronm123&lt;/a&gt;
I meant in a browser, via a second projector probably.</content>

<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>&lt;a href="http://twitter.com/"&gt;web&lt;/a&gt;</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
