I have the below file:

forgeversion.properties, inside is the below content.

```
forge.major.number=4
forge.minor.number=3
forge.revision.number=5
forge.build.number=318

```

I wish to grab the numbers at the end, and then combine them into a format such as:

```
4.3.5.318

```

Just to be more clear, I would like to parse the above data and grab from it the numbers, arranging them into the above new string.

I have already obtained the contents of the file into a variable, ReadVersion.
