.net - How do I guarantee node order for an XPath 'OR' query -

-

i have snippet of xml looks like

<body>    text....    <nodea>....</nodea>    more text    <someothernode>       <nodea>.......</nodea>    </someothernode>    <nodeb>.......</nodeb>      etc..... </body>

i'm selecting nodea , nodeb nodes inside <body> using xpath query similar //nodea|//nodeb

as understand it, .net supports xpath 1.0 not guarantee node order.

how can guarantee selected nodes returned in document order in or query : that's say: 

nodea, nodea, nodeb

as understand it, .net supports xpath 1.0 not guarantee node order

when xpath 1.0 expression selects nodes evaluated, selected nodes form node-set. a node-set set , this, among many other things, means unordered.

for practical purposes, though, there 1 main ordering chosen enumerate nodes of node set: document order. in practice, xpath 1.0 engines know (and in .net) return selected nodes in document order. in future unlikely change, because vendors try preserve backwards compatibility.

therefore, try using selectnodes() or evaluate() methods , verify nodes in results in document order.

do note: order of following cannot guaranteed , implementation-dependent:

  1. attributes of same element.

  2. nodes belonging different documents (a node-set containing nodes different documents can produced using xslt function document(), of no concern you).

cocoa - Nesting arrays into NSDictionary object (Objective-C) -

i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.
