This library includes implementations (mostly taken right from the DSSSL standard) of standard procedures which, at some point in time, were not implemented by Jade/OpenJade (though I think most of them are now built in to newer versions of OpenJade). It also contains useful procedures which are not part of the standard. The procedure in question is defined as such: (define (siblings #!optional (osnl (current-node))) (children (parent osnl))) So, (siblings) uses the "parent" property of the node to go up one level in the grove, then uses the "children-property-name" property of the parent to find the "siblings" of the original node (which would include the node itself). The (rsiblings) procedure, on the other hand, goes up one level in the grove using the "origin" property, then gets the "siblings" using the property of the origin node specified by the original node's "origin-to-subnode-rel-property-name" property. The difference would have to do with what are considered to be the "children" of a node. For instance, an element node has subnodes, usually text and other elements, that are considered its children. It also has subnodes, such as attribute nodes, which are *not* considered to be its children. So, if you had an attribute node, and you wanted to get all of the other attribute nodes of the containing element, the (siblings) procedure would not work, but (rsiblings) would. -Brandon :) DSSSList info and archive: http://www.mulberrytech.com/dsssl/dssslist
