Search for a number within a label?

Scenario:

Gallery with a multiline label (lblDuration)
Sample lblDuration text:
- "This REST service took 50 seconds to execute."
I'd like to set lblDuration Fill based on the number found in the text
Something like: If(Find(lblDuration, > Value("10")), Red, LightGray)
- Which would highlight lblDuration if there is a number greater than 10 found in the text.

The above sample using Find() doesn't work. Neither does Search().
Any other ideas?
THank you!

Will the number always be at a fixed spot? In other words, is the format of that text well defined? Or could the number be anywhere in the string?

Hello @PowerAddict , I appreciate your quick response. The answer is no, the content is not structured in a way to utilize string manipulation.

No problem. One more question: is there an expected range of values e.g. max will be 99?

Here you go:

Set the fill property to something like this:

If(Value(Match(Label28.Text, "\d+").FullMatch)>10, Red, RGBA(0, 0, 0, 0))

Label28 is where my text is. I used your example: This REST service took 50 seconds to execute. You can replace Label28 with your label or wherever the text is. Also, I used Red or No Fill. You can replace RGBA(0,0,0,0) with Gray.

Let me know if this works.

Hi @PowerAddict . Thank you.
I see the solution working in your demo, however porting it to my application doesn't seem to work.
lblGalDuration is the label in the gallery. As you can see, it holds a value of "0.25" in the label. I've lowered the value in the function to "0.1" but it does not trigger...

No problem.

Two questions:
1. Is lblGalDuration where your text is stored? Is it multi-line text? HTML text?
2. If you just put this expression in a label, what do you see?

Match(lblGalDuration.Text, "\d+").FullMatch

Also, your original post did not specify that the numbers will be in decimals. Will they always be in decimals or can they be in either format?

1. Yes, lblGalDuration is where my text is stored. It is a multi-line label.
a. I just changed the value to a whole number, 3. It flagged the "10.9" value, but not the "3.7" value.
b.
2. Placing Match(lblGalDuration.Text, "\d+").FullMatch in a label shows nothing, just blank.
3. Numbers may be whole or decimal.

Is there a max number of digits after the decimal?
