Input -> Parser -> Writer = Input

[burner]

Test if the above shown chain yield an output document where the content is equal to the original input.

Test that with all combinations of lexer, parser and writer.

xmllint's --format option can be used to standardize the formatting of an XML file so that you can use diff. This may simplify writing the tests.

@Hackerpilot thank you.
This will prove very useful, as it will allow me to test on the entire W3 Test Suite without worrying about formatting issues.

@burner Great news!
I had to change the way <!DOCTYPE nodes are handled, but now the library can input and output them easily. This was the only thing that prevented input -> parser -> writer = input to be tested.
Now make test (test driver at source/test.d) runs the chain on every valid file of the W3C XML Test Suite.
Currently the reported failure rate is ~11%, due to the fact that we don't preserve any whitespace, while xmllint preserves some of them (even if all files are normalized with options --pretty 2 --c14n11).

sweet! Awesome job.

If you have the time, maybe just compare the nodes and there attributes. That might give you a more realistic failure rate, but only if you have time.
