Regex measurement like 100x100

I have some text with different measures in that Im trying to exract with regex. a text can look something like this

Ipsum Lorem 3. 100x210 cm
Ipsum Lorem Lorem, 100x210 cm

I have got as far as I can extract the measurements, but when there is an int in the middle of the text ( like option 1) my regex fails. 

([0-9x]+)(?:\^(-?\d+))?

Gets me

Match 1 : 100x210
Match 2  : 3
Match 3 : 100X210

Any suggestion on how I can skip match 2 and only regex INTxINT ?

Thanks in advance

Using a character class [0-9x]+ could possibly also match only xxx or in this case, only 3

The optional group in your pattern could possibly also match 100x210^-2, not sure if that is intended as \^ will match a caret.

To match both the lower and uppercase variant of x, you could use a character class [xX] or make the regex case insensitive.

Using word boundaries \b on the left and right:

\b\d+[xX]\d+\b

Or a more specific pattern using a capturing group, taking matching the cm part afterwards:

\b(\d+[xX]\d+) cm\b

You may use a regex like

\d+x\d+

See proof. It will match two substrings containing one or more digits separated with x character.
