regex pattern to allow positive and negative integers

Question

I am trying to find regex pattern in XSD that allow both positive and negative integers

My current code allows only positive integers.

xs:pattern val         


        

Answer 1

Assuming you only mention an optional negative sign in front of the number:

xs:pattern value="-?[0-9]{0,10}"

Answer 2

Using the \d notation would make it even simpler:

xs:pattern value="-?\d+"

Answer 3

if you using python: example re.findall:

regex=re.findall(r'(-?[\d]+)',somestring)

*output: [negative integer, integer]
