Hello DFDL Community,
My input file contains (among other things) a 2-byte (16-bit) sequence of
flags. Here are the 2-bytes for one input file (in hex):
01 07
Which corresponds to this binary:
0000 0001 0000 0111
Each bit with a value of 1 corresponds to a characteristic (flag):
bit 1 means: Relocation information was stripped from file
bit 2 means: The file is executable
...
bit 16 means: The bytes of the word are reversed
The bytes are in little endian order, so bit #1 is the rightmost bit, right?
I think that for the above example I would like to generate the following XML.
In the above binary there are 4 one's, so I have correspondingly 4
<characteristic> elements.
<characteristics>
<characteristic>Relocation information was stripped from
file</characteristic>
<characteristic>The file is executable</characteristic>
<characteristic>COFF line numbers were stripped from file</characteristic>
<characteristic>The computer supports 32-bit words</characteristic>
</characteristics>
Is that a good way to represent the characteristics (flags)?
I have no idea how to implement this in DFDL. Would you help please?
/Roger
