Global RegExp Stops At First Instance

I'm having some trouble getting a global RegExp to actually go global.
It's testing great at RegExr.com, but when I run it in my actual code, it stops after the first instance. Here's my code.
var strongRegExp:RegExp = /<h3><a title="(.*)" href="(.*)">(.*)<\/a><\/h3>/g;
var matches:Object = strongRegExp.exec(loader.data);
for( var i:String in matches ) {
if (i != "input") {
trace( i + ": " + matches[i] );
Why is this stopping at the first instance? Is it something to do with my loop?

Yes, I do mean that the regex doesn't catch all matches, only the first.
Here's a sample that includes two items it should catch.
<div class="title">
<h3><a title="SEO Article - SEO Optimize Your Website. Free SEO / Search Engine Optimization Lessons / Video. Need Help?" href="http://www.articlesbase.com/marketing-tips-articles/seo-article-seo-optimize-your-website- free-seo-search-engine-optimization-lessons-video-need-help-1268075.html">SEO Article - SEO Optimize Your Website. Free SEO / Search Engine Optimization Lessons / Video. Need Help?</a></h3>
</div>
<div class="title">
<h3><a title="Are You Actually Paying For SEO?" href="http://www.articlesbase.com/seo-articles/are-you-actually-paying-for-seo-3742716.html">Are You Actually Paying For SEO?</a></h3>
</div>
The regex should be able to capture both <h3> tags in their entirety and give me access to the title, the href, and the anchor text.
At least, that's what I'm after.

Can I install a second instance of i-Calender on the server where right now is running the first instance? How?

The first instance is running on a Sun R420 Enterprise
server. The second instance will run in the same server.

When you say "Authorized" you mean in the sense of Itunes Store Authorized? if so the system in Question is authorized it is my primary Workstation and was waiting until iCloud came out to update to Lion. My MBP , and 2006 MP are all running Lion and are part of the 5 systems "authorized". I did not run into this issue with either the MBP or the MP when i installed and I bought two copies at the same time on my the first day Lion was available.
Do you know the mechanism with which the App Store tracks purchases on different computers prior to iCloud coming out?
once again thanks for your response

Compare two columns and match ALL recurring values, not just the first instance

Hi everybody...
I was looking for a way to compare values in two columns, identifying every duplicate value instance on a third column.
Searching around the forums, I found a solution, albeit a partial one; I am using this formula: =IFERROR("Duplicate in row "&MATCH($A,$B,0),"") along column C, to compare values between columns A and B. When applied, the formula will render the first instance where there is a duplicate; unfortunately MATCH will only register the first instance of the duplicated values.
For example:
The first value on column A is 'Apple'. On column B there are three instances for the value 'Apple', the formula identifies the first of these values, but not the remaining two.
I am not an advanced Numbers or Excel user, and the answer to this problem eludes me. I am attempting to compare columns that have no less than 1000 rows each, so you can imagine how, finding a solution to my problem would be really great.
Thanks in advance,
Pablo

Unfortunately I can't see your screenshot, but supposing you have a table like this:
Col1
Col2
1
3
Dupe
2
4
Dupe
3
5
Dupe
4
6
5
7
Then here is one way to flag the duplicates.
The formula in C2, copied down, is:
=IF(COUNTIF($A,$B2)≥1,"Dupe","")
Then filter on column C for 'Dupe', and copy the values in column B to wherever you need them.

Interactive buttons on master pages only appearing on first instance in document [CS6]

I have a document being created for on-screen use that has next and previous buttons in the design. These buttons are on the master page with the 'On Click go to next/previous page' behaviour applied.
When the document is exported the buttons only appear on the first instance of that master page. IE. If pages 2-20 are created from that master, the buttons only appear on page 2.
I've seen other people reporting this problem in some other threads without an answer, so hopefully someone will see this who knows what the issue is.
I presume this is something to do with CS6, this is occuring in a document that was originally created in CS3 or 4. It's been revived for a new edition, and the buttons used to work perfectly under the old version, but now they're behaving as described. I've recreated them from scratch as well as using the previous version, but the results are the same.

Wasn't there an Acrobat issue that affected this as well? Make sure that is updated, too.
While I'm on it, this is being viewed in Acrobat/Reader, right? Anything else, especially Mac Preview is a bit of crapshoot.

I am trying to write a grep search for the first instance of a word in a paragraph.

How can I identify only the first instance of 'FREE' in a paragraph and apply a style to it, without also styling the 2nd or more instance of the word?
Thanks

(?i)^(.+?)FREE should find the first instance in a paragraph. The (?i) makes the search case insensitive in case it wasn't typed as all caps, the ? inside the second grouping makes the shortest match for cases when there is more than one instance in a paragraph, and I've not added any quotes since I presumed those aren't actually in the text.
I would deal with the formatting by typing FREE exactly as you want it someplace on the pastebord, then copy to the clipboard. Change to $1~c which replaces the found string with the text found in the first subexpression (.+?), which is the stuff before the first FREE, and the the formatted contents of the clipboard for the FREE.

How to stop after first loop operation over?

Hi friends.
How to stop after first loop operation over?
I have a loop operation in module pool program.
After first loop over I want to stop.
I used the STOP keyword, but it is going to dump.
Thanking you.
Regards,
Subash

Hey,
The statement STOP is forbidden in methods and, since release 6.10, leads to an uncatchable expection during the processing of screens called with CALL SCREEN...
As they said above, use a EXIT statement to fix this DUMP...

In search in Safari on my Ipad how do I stop multiple first letters typed

In the search feature of Safari how do I stop multiple first letters from automatically being entered. Example if I entered an A as the first letter it enters automatically 3 A's, This is frustrating to always have to delete 2 of the letter A to be able to continue entering my Question or what ever I may be searching for? Any help is appreciated. Thanks

I don't know what you are getting multiple letters in the search (URL) field in Safari. If you get double caps or double letters when you type in the text area here in the ASC forum, that is because of a bug in the Jive Software that Apple utilizes to run the forum. There is nothing at all that you can do to fix that.
If you really are getting double or triple letters in the URL field - that is the search field in Safari in iOS 8, try clearing Safari. Settings>Safari>Clear History and Website Data. Then reset the iPad by holding down on the sleep and home buttons at the same time for about 10 seconds until the Apple logo appears. Let go of the buttons and let the iPad start up.

GREP: Apply to first instance only

Hi,
Another GREP question for you if you can help.
Situation is trying to apply a character style before a specific word, i.e. Applied Character Style "four".......
There are 4 words (lets call them: one, two, three, four) which are a common occurence and will always appear after the text that needs to have the applied character style, but my issue crops up when one of the four words appears twice or more times in one line and the GREP applies it to the 2nd or more instance of this word, i.e. Applied Character Style "one" random text "one"
I am using these greps in the same paragraph style:
^.*(?= one)
^.*(?= two)
^.*(?= three)
^.*(?= four)
I only want to have the GREP to apply to the first instance only - hope this stuff above makes sense?
Thanks

It's because GREP is greedy, by default.
The expression
^.*(something more)
will always grab as much characters as possible, before processing "something more": effectively, it will match anything up to the very last occurrence of that text.
You can instruct GREP to not match greedy by adding a '?' after the repeat command code:
^.*?(?=\b(one|two|three|four)\b)
-- the question mark can be added to each of the "repeat-this" codes: +, *, and ? ("!??" would mean: "match '!' zero or once, but uses the shortest match possible).
I condensed your list of four commands into one, because it seems to me that all of them would get matched in turn, leading to problems when you have both "one" and "two" in the same sentence. With your GREPs, first all up to "one" would get marked, then all up to "two". Mine uses 'whatever comes first'.
(I also added 'word boundaries' \b before and after, because you wouldn't want to match the 'one' in "Mr. Jones".)

Starting and Stopping an FMS Instance?

Hi there,
I'm sorry if this issue has already been answered somewhere else, but my Google skills are up to par and I was unable to find a documented resolution to this problem within the last few days. Opening a new topic was my last resort.
I am designing a live-streaming system for a client. We've been running an instance 24/7 for the last month and my client just received an enormous bill for that.
Basically we need to be able to start and stop the instance as needed. When I check the checkbox next to it in the Management Console and click on Instance Actions, Stop and Start are greyed out. I am allowed to Terminate and Reboot the instance, but I'd like to keep my same instance and simply turn it on and off in between live streams. I've read that the Start and Stop options are disabled because my instance is not stored on an EBS volume, and that running FMS on an EBS volume is not supported. Must I leave the instance running all the time in order to get around having to set it up each time I need it? Is there any sort of workaround or widely accepted answer for this?
Thanks again.

Hi Smit,
I believe you are talking about FMS AWS instance and you may be using a centos 4.0.2 instance AMI or lower?
Well ... earlier, options for stopping a centos AWS image was not available, but recently they are there in place, so I suppose if you use a new centos 4.5.1 AMI then probably you can start stop the aws instance on yuor will. Give ut a shot and let me know.
Regards,
Shiraz Anwar
I again cross-checked and found that you were right, start and stop is not supported there .... an alternative method is to take a snapshots of the runinng instnace and terminate that instance after that, later you can use your snapshot to attach to the EBS volume to run your system again. You may need to use the Elastic IP address, because you wont like your users to update each time you terminate the old instance, and create new instance from snapshot. I have never used it in this way, but this is one of the approach.

I bought the APP Sasol Birds. 146MB of the 147,5MB downloaded without any problem. The download stopped and first the error code 3259 and later the error code 8012 appeared. Can someone help? I want the download to be completed. Thank you. Pieter Strobos

Maybe your firewall or security software are preventing the download from finishing. You could try disabling them until you finish the download

How do I stop the first slide to be the name of the Album?

I've created a slide show but cannot figure out how to stop the first slide from being the name of the album against a black background. I'd just like for the first slide in the show, to be the first slide in the show.
Thanks.

I have a similar problem, though not with a title. (I have unchecked the "Show Title Slide" option.)
Why, when I export a slideshow under the Slideshow tab, does it generate a black first slide? How do I get it simply to start with the first photo?

I need help writing a script that finds the first instance of a paragraph style and then changes it

I need help writing a script that finds the first instance of a paragraph style and then changes it to another paragraph style. I don't necessarily need someone to write the whole thing, by biggest problem is figuring how to find just the first instance of the paragraph style. Any help would be greatly appreciated, thanks!

Hi,
Do you mean first instance of the paragraph style
- in a chosen story;
- on some chosen page in every text frames, looking from its top to the bottom;
- in a entire document, looking from its beginning to the end, including hidden layers, master pages, footnotes etc...?
If story...
You could set app.findTextPreferences.appliedParagraphStyle to your "Style".
Story.findText() gives an array of matches. 1st array's element is a 1st occurence.
so:
Story.findText()[0].appliedParagraphStyle = Style_1;
//==> this will change a paraStyle of 1st occurence of story to "Style_1".
If other cases...
You would need to be more accurate.

Create return but linked to original sales order where the material was delivered in the first instance

Hi Everyone
I want to create return but linked to original sales order where the material was delivered in the first instance, I don’t want to create other sales order (to return) with references to the original, and then other sales order to be delivered again (replacement).
Example
SALES
1. Create a sales order number 33 with 10 Ton
2. The delivery is linked to sales order 33 just with 8 Ton
3. Invoice is created linked to the delivery with 8 Ton
4. Sales order number 10 pending qty is 2 Ton
RETURN
5. We would like to link the return delivery to the sales order, 5 Tons will be retuned
6. Credit memo is created
7. Sales order number 10 pending qty update to 7 Ton

The only way is to change the item categories in the delivery.
Create the delivery wrt the original sales order.
Change the item category(In the config make sure the return is checked)- But I think you need to do some changes in the user exit to enable the item category in the delivery)..
The other option is to have a return order document(type RE) and then create the return delivery for this document. In the copy controls you can maintain the return item categories while creating the return order from sales order..
Thanks

Hide all instances of text fields, instead of only first instance?

Hi All, Been scouring looking for an answer to this, and tried several things that I haven't been able to make work for me.
I'm creating a quote form in LC Designer.
I've got buttons to add or remove instances of a subform. The subform contains 5 fields. I need to add a checkbox that will hide only 2 of the fields within the subform when checked, and when unchecked, show them again. I am able to make this work, but only for the first instance (instance 0?). How can I make this work so it hides these fields from each of the visible instances?
You can view the form at: https://workspaces.acrobat.com/?d=GVqRa5BfyIKxpkAVBxje3Q
For anyone that is feeling abitous, what I really wanted to do seems impossible, so I'm going with the above as a simpler workaround. What I really want to do is have a check box that when clicked, will hide the quotation form, and make the purchase order visible, carrying over any field data into a new table on the Purchase order form from the quote form. I've attached this form at https://workspaces.acrobat.com/?d=pqpsXx5VPi*LkMeVKrX57w
I understand that I need to create an XML schema to accomplish this, but can't figure out for the life of me how to actually create the schema. I can only find info on how to bind the data source once it's been created.
I would be forever grateful to get a hand with getting either of these forms to do what I need.
Thank you!

Hi Barb,
The first question is fairly easy, you need do exactly what you were doing but for all the rows, so;
var newPresence = (this.rawValue == "1") ? "hidden" : "visible";
var rows = page1.resolveNodes("Subform2[*]");
for (var i = 0; i < rows.length; i++)
    var row = rows.item(i);
    row.Col2.presence = newPresence;
    row.Col4.presence = newPresence;
The second one can be done, but is a bit fiddly. I have updated your sample, https://workspaces.acrobat.com/?d=jLYZGae--BiZ0khRbZqvuA
This relies on having two top level subforms, one for Sales_Quotation and one for Purchase_Order, when you click the checkbox the name of the top element in your data connection is updated, the form is remerged and rendered with the top level subform that matches the new name. Look in the hierarchy tab and you will see what I mean by top level subform. Any elements that have the same binding under the Sales_Quotation and Purchase_Order subforms will bind correctly. You wont need an XML Schema.
The fiddly bit is that in Designer you can only edit the first top level subform in the form, the second one wont show up at all at design time. However, the approach was discribed in this blog http://blogs.adobe.com/formfeed/2011/02/multiple-top-level-subforms.html and John has a macro to move the first subform become the last. I've already run the first macro, NewTopSubform, so you just need the RotateSubforms macro. There's more information on macros and how to install them in the Designer help http://help.adobe.com/en_US/enterpriseplatform/10.0/DesignerHelp/WS3041177a02dcf48e2f8c933 d12daa5a53a3-8000.html
Good luck
