Dumping SWF Files Generated from MXML Applications

This section provides a tutorial example on how to dump and disassemble SWF files generated from Flash applications written in MXML format. '-D' and '-asm' options should be used.

In this example, let's dump and disassemble a SWF file generated from a Flash application written as an MXML file, sqft_converter.swf. See previous chapter on how sqft_converter.swf was created.

First dump it with the SWFTools SWF dumper using "-D" option:

C:\herong>\local\swftools\swfdump -D sqft_converter.swf

[HEADER]        File version: 10
[HEADER]        File is zlib compressed. Ratio: 49%
[HEADER]        File size: 80395
[HEADER]        Frame rate: 24.000000
[HEADER]        Frame count: 2

     staticconstructor * =()(0 params, 0 optional)
    [stack:0 locals:1 scope:3-3 flags:]
    {
        00000) + 0:0 returnvoid 
    }

     constructor * <q>[public]mx.core::IFlexModuleFactory=()
        (0 params, 0 optional)
     getter <q>[public]flash.utils::Dictionary 
        <q>[namespace]mx.core:IFlexModuleFactory::preloadedRSLs=()

[000]         0 END

Then disassemble it with the Flex SWF disassembler using "-asm" option:

C:\herong>\local\flex\bin\swfdump -asm sqft_converter.swf

                    </attrs>
                    ...
