Extracting a number from a text field

Question

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})
" );

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

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: And finally regex with same text:

Names Default To Here(1);text ="UDI# 123456789123456789123456789456123Device received, missing cover.Major Reason For Service: xxxxxxxxxxSystem usage: 2372System PM due in: 7627xxx usage: 120yyy usage: 208";//note "\2"matchRegex = Regex(text, "(System usage: )(\d{1,5})", "\2");Show(matchRegex);//note index of numbermatchList = Regex Match(text,"(System usage: )(\d{1,5})");Show(matchList);Show(matchList[3]);
