Extracting an increasing number from a line of text

[shaunreed1]

Hi, 

I am new to BP and struggling to fine a guide for expressions.  I understand how to use the expression builder but sometimes It isnt always fit for purpose so a guide detailing loads of expression strings would be great to aid my learning.  

My current issue is that I want to extract a number at the end of a line of text.  "Your order ref is 15", i used the expression RIGHT to get the last 2 digits however when the order number reaches order 100 then the expression will no longer be fit.  How can I extract an ever increasing number - Please reply in the simplest form to aid my understanding. 

Thanks in advance!

I've been thinking and is it possible to maybe take the fill text and minus off the text leaving the number?

Hello @shaun reed, if your text has variable number length, you can use Utility String VBO​ "Extract Regex Values" action. This will give you the extracted value of however many numbers from your string in a collection. The Coll1 collection should have 2 fields Name and Value. In the Initial Value add one row, where Name will have OrdNo and keep value blank. Hope this helps.

Hi,

This really helped.  I was wondering if you can help with another one.  I have extracted the order ref number now and it is sitting in a data item in the business object page.  I need to pass this to the process page.  How do I do this? The data item is called Order Ref.

Im assuming it would need to go into a collection so it will collect all of the orders.  This is part of training. ​

You can pass the data item via the End stage. So, open end properties and add your data item there. In your process when you are calling that object via action, open the properties, and accept that value in the Outputs.
Hope this helps

You can also Replace( [your_text] ,"Your order ref is ","") => "15" if string is always the same and just number changes.
