[PATCH] (#2) Make xmlgen.c use libxml2 instead of hacking it out manually
by Dan Smith 03 Dec '08

# HG changeset patch # User Dan Smith <danms(a)us.ibm.com> # Date 1228323360 28800 # Node ID 837fbfdeafbbbd071001d3487e1916497e22909f # Parent 03af2846604b1fdc8d1d7fa3aef737f727b0414b (#2) Make xmlgen.c use libxml2 instead of hacking it out manually Now that our XML generation is getting complex enough, I think it's worth using libxml2 to build a proper DOM tree and XML string. Note that due to the invasiveness of this patch, it's almost unreadable. It may be easier to review after it's applied to the tree. Also, it deserves some serious review and testing for correctness and error-handling abilities. Comments on this approach are welcome too, of course.

[PATCH] Make xmlgen.c use libxml2 instead of hacking it out manually
by Dan Smith 03 Dec '08

# HG changeset patch # User Dan Smith <danms(a)us.ibm.com> # Date 1228236226 28800 # Node ID c34ae7c0ded8870aeba40a0798ac31f1ea2c5bbd # Parent 6e8a488cf67b47efb618c28aa2a9104d5b0e1b91 Make xmlgen.c use libxml2 instead of hacking it out manually Now that our XML generation is getting complex enough, I think it's worth using libxml2 to build a proper DOM tree and XML string. Note that due to the invasiveness of this patch, it's almost unreadable. It may be easier to review after it's applied to the tree. Also, it deserves some serious review and testing for correctness and error-handling abilities. Comments on this approach are welcome too, of course.
