XML(-ish) output?

XML(-ish) output?

[Albretch Mueller]

 I couldn't find any reference to generating output files as XML
documents in sourceware's documentation per se, even though in the
mailing list
~
 http://sourceware.org/ml/systemtap/
~
 I did find some comments of people asking for xml-esque output
~
 I somehow expected to find something like that and I think this
shouldn't be that hard because the logic followed by the state
machines used by compilers is very much patterned and hierarchical
~
 Is there a way to have strap reports as xml? Or in case there isn't
in a straightforward way, what would you suggest?
~
 thanks

One can do so from first principles:

    probe FOO {
          printf("<tag attrib=\"foo\">\n");
          printf("<bar/>\n");
          printf("</tag>\n");
    }

How much deeper support for xml generation were you hoping for?
Quoting of some sort?

I've once experimented with utility functions providing brackets and the end tag, but I ran into problems with the maximum string length when nesting. So most of the output was from first principles as above.

function tags( name, content )
{
  return sprint( "<%s>%s</%s>/n", name, content, name );
}

 Well, as deep as necessary. Why should depth matter? Shouldn't
generating an XML-ish stack be straight forward?

 Anything that would let me test its output by generating an XML dump
and then somehow reconstruct original dump based on the XML feed, so
things is idempotent
~
 My intention isn't really hacking into binaries, but somehow getting
and tracking -detailed- dependency relationships in binaries and how
they relate to source code. Maybe you know of a better tools or you
have a better idea about how should one approach such a task
~
 Any suggestions?
