Hello, hope one of you can see what I'm struggling with here.....;

I'm trying to extract value from a Zone OCR, using script sample from this link:

https://forum.scanshare.com/thread/script-extracts-a-part-of-a-string-that-corresponds-to-a-regular-expression/

The problem I have is first of all, I'm not experienced in scripting, but normally I understand enough to edit simple examples. This time I was unable to...

The problem I have when using the script is that it will find several matches from my RegEx in the zone, but I should have the value from the first hit. I get the value from the last hit instead, and I don't understand what to change in the script to make it only get the first match.

This is the script (so I have only made some minor changes):

--------------------

'###Variable definition area
'The user need to define the name of the metadata that is used as input sSearch = Metadata.Values("metadata")

sSearch = Metadata.Values("OCR_ZONE01")
'The user need to define the regular expression to be used on the metadata sPattern(1) = expression
DIM sPattern(1)
sPattern(1) = "\d\d[\,\.]\d\d[\,\.]\d\d"
FOR I = 1 TO 1
   call Application.Log(20, "Pattern to search: " & sPattern(I))
   call TestRegExp(sPattern(I), sSearch)
NEXT

Sub TestRegExp(sPattern, sSearch)
   ' Do the regular expression match
   Dim oRE, oMatches
   Set oRE = New RegExp
   oRE.Global = True
   oRE.IgnoreCase = True
   oRE.Pattern = sPattern
   Set oMatches = oRE.Execute(sSearch)
   Dim oMatch
   For Each oMatch In oMatches
        call Application.Log(20, "Find part: " & oMatch.Value)
        call Metadata.SetValues("PART_OCR_ZONE01",oMatch.Value)
   Next
End Sub

--------------

Anyone have an idea?

Thanks in advance

Hi Anders,

no problem, you always assume that everything is almost possible in Scanshare .

For your script above it depends on what you have in the variable (oMatches) that you loop in the for. From your previous message, I think it is an exit for question so maybe you could solve it with a simple part of code looks like this:

...........

For Each oMatch In oMatches

call Application.Log(20, "Find part: " & oMatch.Value)

call Metadata.SetValues("PART_OCR_ZONE01",oMatch.Value)

Exit For

Next

............

or you can directly access the first element of the array:

............

Dim oMatch

oMatch = oMatches(0)

call Application.Log(20, "Find part: " & oMatch.Value)
