find number in a string

[roberto aranibar]

Dear ImageJ users,

Does anyone know an easy way to find a 1 to 4 digit number (unknown) within
an ROI name? I have this so far:

requires("1.37q")
for(index=0; index<roiManager("count"); index++) {
name=call("ij.plugin.frame.RoiManager.getName",index);
iFirst=indexOf(name,####);
iLast=lastIndexOf(name,####);
number=substring(name,iFirst,iLast);
}

Thanks in advance for any help/ideas anyone can offer?

Roberto

    n = "";
    for (i=0; i<lengthOf(name); i++) {
        c = substring(name, i, i+1);
        if (c>="0" && c<="9")
            n = n + c;
    }
    n = parseInt(n);
