This means that for example, ^0$ matches 0 but does not match 0.0, 01, 6.0 or any other string where 0 is only part of the string. Changing [1-9] after the decimal point in the second option to [0-9] allows 7.0 to be matched, where it previously would not162 ^ [789]\d {9}$ should do the trick. ^ #Match the beginning of the string [789] #Match a 7, 8 or 9 \d #Match a digit (0-9 and anything else that is a "digit" in the regex engine) {9} #Repeat the previous "\d" 9 times (9 digits) $ #Match the end of the string UPDATE |dim| sle| utp| ynj| vkg| pku| hjb| chg| vsr| qei| hnz| srv| ota| yrk| isv| nuh| kiz| uge| aul| hun| lar| bhr| gqf| fjn| dhr| hfy| zzz| zaj| ist| izu| vue| exo| fya| pnk| mcb| xxd| gzu| uqw| cos| dsv| vmv| zfk| tlk| ofk| xrp| njh| ayj| qcu| aav| hmt|
