How do I parse a text file for coord pairs?

Vaughn

I want to read a file and return a list of all the coord pairs in the file. Due to the unknown seperator between coord. I want to return any two number pairs per line.

I can use the while command to parse strings but am unable to find how to parse for numbers while reading a file.

    Assume the variable line has one line from the file. Then run the following code to store the coordinates in variable coord:
            rexCompile( "[xyXY] *[=:]")
            coord = rexReplace( line " " 0)
            rexCompile( "[(){}=,:]")
            coord = rexReplace( coord " " 0)
            rexCompile( "\\. ")
            coord = rexReplace( coord " " 0)
            coord = parseString(coord)
            ;Get only the numbers from the rest of the data
            coord=mapcar( 'aelNumber coord)
            ;Keep non-nil values
            coord=setof(x coord x)
