Re: XML query language and another OS/XML suggestion
Yes, the pipe mechanism takes on whole new meaning with XML. It wouldn't be all that large of a job to do a lot of it. Obviously adding --XML capabilities wouldn't be that tough since it's simply adding labeling tags to output that is already formatted. Even /proc/xml wouldn't be that hard for output, a little tougher for input, but allowed input would be so restrictive that a simple regex parser would suffice for most things. Hacking bash in an appropriate way is more difficult, however there is already an sgrep (SGML grep) and external tools can handle all of this like Perl, Java, Tcl/TK. I suppose what we need is a group to start standardizing a DTD that settles what to call everything in a system (ports, network address, process/thread, user, etc.). That's probably the biggest job. sdw Oren Ben-Kiki wrote: > Stephen D.
