Using Bookmark Names to create Custom Stamps

Question

Hi all,
  I am a VB programmer that is struggling with a task in JS.  I am trying to do 1 of 2 things:  I would prefer #2.
1.Create a custom stamp using the filename.
or
2.Create a custom stamp using the bookmark name (which in turn will be the filename)
I have been foooling around for a number of hours trying to get this to work out, here's what I have done so far:
I have created a stamp, the stamp has two text boxes that I need to fill from one string. The string is in the format of
"08363-G-5109-DWG-R-00001_A.pdf" with a varying number of characters before the underscore, but always the same after the underscore. In the first text box I need
08363-G-5109-DWG-R-00001 which I get with
Code:
event.value = event.source.source.documentFileName.slice(0,-6); this work great. The second box needs to contain the letter(s) that are between the "_" and the ".pdf" and everything I have tried doesn't produce a result.
I focused most of my time trying to split the filename up, figuring the same logic would be applied to the bookmarks.
The things I have tried:
[CODE]
var str = event.source.source.documentfilename;
var strt = str.lastindexof("_");
var end = str.lastindexof(".");
event.value = str.substring(strt,end);
and
var arrStr = event.source.source.documentfilename.split("_");  ' **Harcoding = "08363-G-5109-DWG-R-00001_A.pdf" works**
var arrstr2 = arrStr[1].split(".");                                             'But isn't very dynamic
event.value = arrstr2[0];
and
var str = event.source.source.documentfilename;
var arrStr = str.split("_");
var arrstr2 = arrStr[1].split(".");
event.value = arrstr2[0];
[/CODE]
Any assistance would be greatly appreciated!

Answer 1

GJ - The bookmark would be selected manually and the stamp would reflect the change.  The sole purpose of this is to combine and stamp hundreds of documents in the most efficient manner.
So for example:
I combine 3 docs by selecting them in Windows and right clicking and selecting combine:
08363-G-5109-DWG-R-00002_A.pdf
08363-G-5109-DWG-R-00002_B.pdf
08363-G-5109-DWG-R-00002_C.pdf
I would have 3 bookmarks automatically when the combination occurs:
08363-G-5109-DWG-R-00002_A
08363-G-5109-DWG-R-00002_B
08363-G-5109-DWG-R-00002_C
So when I select the bookmark 08363-G-5109-DWG-R-00001_A then click stamps - dynamic stamps , my two text boxes have used this bookmark to get                 Text 1                          Text 2
                                                                       08363-G-5109-DWG-R-00001     A
Then I manually select the next bookmark and select stamp and it has used the next bookmark name to create a stamp  with two text boxes now              08363-G-5109-DWG-R-00002      B
If I had to stamp them first them combine, I would have to open one, stamp, save close rinse and repeat 100 times then combine.
GK - I did have a poke around with bookmarkRoot.children, but the only result I ended up with was the word "Root" in the second box.  I couldn't seem to determine if JS automatically builds the children collection based on the number of bookmarks off the root, or if I had to programmatically build it with an array.
