Can you give an example of your input data and what you expect
the return value to look like?

When you say it is a hex representation of binary data do you
mean something like:


"Here is some text with a hex number, 0xAB23C, embedded in it"

If so then you don;t need to convert to hex, you just need a string
search.

But I'm not clear exactly what kind of data you are dealing with.

It might help if you posted some code too. And tell us what
happens when you run it, and why that was not what you wanted to happen...
