Match a string with a word and a digit 1-9

Question

My regex is weak, in the case of the following string

"OtherId":47
"OtherId":7
"MyId":47     (Match this one)
"MyId":7

I want to pick up the string that has "MyId" and a number that is not 1 - 9

I thought I could just use:

But its not happening... you can see my failed attempt here:

Which is

\b"MyId":\b(?=.*^[0-10]\d)

What am I doing wrong?

You can use this regex to match any digit >= 10:

^"MyId":[1-9][0-9]+$

If leading zeroes are to be allowed as well then use:

^"MyId":0*[1-9][0-9]+$

[1-9] makes sure number starts with 1-9 and [0-9]+ match 1 or more any digits after first digit.

If leading zeroes are to be allowed then use `^"MyId":0*[1-9][0-9]+$` – anubhava Dec 14 '17 at 11:25

Essentially, you are looking for 2 or more digits:

\"MyId\"\:(\d{2,})

I have escaped the quotes and colon, and {2,} means 2 or more.

"_higher than 10_", but `10` would match too ;) – AxelH Dec 14 '17 at 11:19

`\d{2,}` will also match `01` or `00` – anubhava Dec 14 '17 at 11:20
my bad, my question technically had 2 questions "higher then 10" and 0-9 , AndyG is right, I will edit the question to be less ambiguous – chrispepper1989 Dec 14 '17 at 11:20

Yes, I was looking at the sample regex which had `^[0-10]`, persuading me to look above 10. – Andy G Dec 14 '17 at 11:22

That is why there should be a single, clear, question :). Go with @anubhava 's answer as it is the more informative and popular. I won't lose sleep... ;) – Andy G Dec 15 '17 at 10:10
I know, I really failed that day! lessons learnt for sure! Cheers Andy :) – chrispepper1989 Dec 18 '17 at 11:04

If you need exact match to any number greater than 9 ^"MyId":[1-9][0-9]+$
