So I have a column of long text strings that essentially are made up of '&'s followed by an alphabetic code, and then an '=', and finally, a bunch of numbers (varying lengths).

here is a sample:

...&abc=123435&defg=54321&hijklmno=14&...

I want to extract from the sample above the following:

defg=54321

I know Im always extracting defg=, but I do not know where it is in the cell, and I do not know how many numerals come after the = and before the following &.

Any ideas??
