String conversion and concatenation

Question

I have the following line of XML:

<indexentry><secondaryie>definition, 3/2/4</secondaryie></indexentry>

And I need a regex that matches the above and converts it as below:

ABC3(the first number)/P-2(second number)-4(third number)

How can I do this?

Regex (at least alone) are not a great tool for this. Use an XML parser. — Konrad Rudolph, Oct 22 '13 at 12:50

Use this regex:

([0-9]+)/([0-9]+)/([0-9]+)

And from captured groups #1, #2, #3 make your string:

ABC3\1/P-2\2-4\3
