[xml] xmlDocDump() generates output on one line

["Yong Chen (yongche)" <chen cisco com>]

Hi,

In FAQ, it states xmlDocDump outputs to one line only (which is true),
the #1 suggestion is "to generate those yourself too", can you please
elaborate it?

Do you mean we should traverse the doc tree ourselves to print out nodes
with indentation, or we need to add space and carriage return when
creating the nodes so xmlDocDump will print out the nodes nicely?

Thanks,
