Data-driven application --> the data is essentially "machine code" tothe

Hi Folks,

Suppose you have data that drives an application. Maybe the data is something like this:

<Document>

    <item>data1</item>

    <item>data2</item>

    <item>data3</item>

</Document>

The application performs this loop:

1. read the next piece of data

2. perform an action based on the data

3. if no more data then done else goto 1.

That is how a CPU behaves, right? So the data is essentially “machine code” to the application, right?

The data could be a list of XPath expressions. Then the XPath expressions are essentially machine code, right?

Machine code is usually produced by a compiler. That is, a higher level language is compiled into machine code. Have you created a higher level language which you “compile” into data that then drives an application? What is the higher level language?

Have you ever “reverse engineered” data? That is, have you reverse engineered data to produce a higher level language?
