Extracting a number from a text field

I have a column containing text notes entered by technicians. They enter the system usage hours, which I need to extract into it's own column. Fortunately, the data is pretty consistent, and so I have been able to pull the info out using Regex Match(), but selecting the last value is tripping me up.

Regex Match( :diagnosis, "(ys.+sage: ?)(\d{1,5})\n" );

How do I extract the System Usage hours from the text block effectively?

 

Sample text looks like this:

UDI# 123456789123456789123456789456123

Device received, missing cover.

Major Reason For Service: xxxxxxxxxx

System usage: 2372
System PM due in: 7627
xxx usage: 120
yyy usage: 208

Here is a solution that uses JSL functions to extract the System Usage

Num( Word( 1, Substr( :Diagnosis, Contains( :Diagnosis, "System usage:" ) + 14 ), "\!n" ) )

I have attached the above data table

Re: Extracting a number from a text field

If the data is consistent enough you could do this without regex by using Substr with Contains (and Length)

Names Default To Here(1);
text ="UDI# 123456789123456789123456789456123

    Device received, missing cover.

    Major Reason For Service: xxxxxxxxxx

    System usage: 2372
    System PM due in: 7627
    xxx usage: 120
    yyy usage: 208";
  
stringToSearch = "System usage: ";
sysUsage = num(Substr(text, Contains(text, stringToSearch) + length(stringToSearch), 4));
show(sysUsage);

Edit1: Or by using Words and Word:

Names Default To Here(1);
text ="
UDI# 123456789123456789123456789456123

Device received, missing cover.

Major Reason For Service: xxxxxxxxxx

System usage: 2372
System PM due in: 7627
xxx usage: 120
yyy usage: 208";

list_of_rows = Words(text, "\!N");
Show(list_of_rows);
sysUsage = Word(3, list_of_rows[4]);
Show(sysUsage);

Edit2: </CODE>And finally regex with same text:</P><PRE><CODE class=" language-jsl">Names Default To Here(1); text =" UDI# 123456789123456789123456789456123 Device received, missing cover. Major Reason For Service: xxxxxxxxxx System usage: 2372 System PM due in: 7627 xxx usage: 120 yyy usage: 208"; //note "\2" matchRegex = Regex(text, "(System usage: )(\d{1,5})", "\2"); Show(matchRegex); //note index of number matchList = Regex Match(text,"(System usage: )(\d{1,5})"); Show(matchList); Show(matchList[3]);
