is it possible to detect if an xml node is present using c#? -


i have xml file , want know if possible see if <vertrekvertragingtekst> present in xml file.

this xml node:

<vertrekkendetrein> <ritnummer>4722</ritnummer> <vertrektijd>2014-06-03t09:45:00+0200</vertrektijd> <vertrekvertraging>pt2m</vertrekvertraging> <vertrekvertragingtekst>+2 min</vertrekvertragingtekst> <eindbestemming>uitgeest</eindbestemming> <treinsoort>sprinter</treinsoort> <vervoerder>ns</vervoerder> <vertrekspoor wijziging="false">2</vertrekspoor> </vertrekkendetrein>

(these nodes in dutch dont pay attention say, not important)

this c# code have far:

xmlnodelist nodelist = xmldoc.selectnodes("actuelevertrektijden/vertrekkendetrein/*"); foreach (xmlnode nodelist2 in nodelist) {                         if (i < 1) //1         switch (nodelist2.name)         {             case "vertrektijd": string kuttijd1 = (nodelist2.innertext);                 var res1 = regex.match(kuttijd1, @"\d{1,2}:\d{1,2}").value;                 lblv1.text = convert.tostring(res1); break;             case "vertrekvertragingtekst": ververt1.text = (nodelist2.innertext); ververt1.visible = true; vertpic1.visible = true; logo1.top -= 9; lblts1.top -= 9; break;             case "eindbestemming": string vertrek1 = (nodelist2.innertext); if (vertrek1 == "uitgeest") { lblvia1.text = "krommenie-ass"; } lblbs1.text = vertrek1; break;             case "treinsoort": lblts1.text = (nodelist2.innertext); break;             case "routetekst": lblvia1.text = (nodelist2.innertext); break;             case "vertrekspoor": lbls1.text = (nodelist2.innertext); i++; break;         } }

i can read out of file , works want know how can detect presence of node?

use selectsinglenode method

var result = node.selectsinglenode("nodetocheck"); if(result!=null) { }

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
