Just so I understand the reasoning correctly - you're not doing this so you can use virXMLPropString() instead of virXPathString(), but just so you can remove the "adapter" from the path to each attribute (and in the cases where that turns a "path" into simply the attribute name, you're switching to virXMLPropString() because it's presumably slightly more efficient. Right? Or is there some other reason you prefer virXMLPropString()? > > Signed-off-by: John Ferlan <jferlan(a)redhat.com&gt; > --- > src/conf/storage_conf.c | 51 ++++++++++++++++++++++++++----------------------- > 1 file changed, 27 insertions(+), 24 deletions(-) > > diff --git a/src/conf/storage_conf.c b/src/conf/storage_conf.c > index 1993d3a..4fa7c12 100644 > --- a/src/conf/storage_conf.c > +++ b/src/conf/storage_conf.c > @@ -464,13 +464,17 @@ virStoragePoolObjRemove(virStoragePoolObjListPtr pools, > > static int > virStoragePoolDefParseSourceAdapter(virStoragePoolSourcePtr source, > + xmlNodePtr node, > xmlXPathContextPtr ctxt) > { > int ret = -1; > + xmlNodePtr relnode = ctxt->node; (This is the first time I've seen "relnode" used to save a ctxt->node. When I look through the source, the one other place I see it is in virxml.c (other places use "node", "save_node", "oldnode", "save_ctxt", "tmpnode", and on an on). Now I'm trying to figure out what "rel" stands for but nothing comes to mind. How stupid am I?)
