ruby - Opening multiple html files & outputting to .txt with Nokogiri -


just wondering if these 2 functions done using nokogiri or via more basic ruby commands.

require 'open-uri' require 'nokogiri' require "net/http" require "uri"  doc = nokogiri.parse(open("example.html"))  doc.xpath("//meta[@name='author' or @name='author']/@content").each |metaauth| puts "author: #{metaauth}" end  doc.xpath("//meta[@name='keywords' or @name='keywords']/@content").each |metakey| puts "keywords: #{metakey}" end  etc...

question 1: i'm trying parse directory of .html documents, information meta html tags, , output results text file if possible. tried simple *.html wildcard replacement, didn't seem work (at least not nokogiri.parse(open()) maybe works ::html or ::xml)

question 2: more important, possible output of meta content outputs text file replace puts command?

also forgive me if code overly complicated simple task being performed, i'm little new nokogiri / xpath / ruby.

thanks.

i have code similar.
please refer to:

module myparser   html_file_dir = `your html file dir`   def self.run(options = {})     file_list = dir.entries(html_file_dir).reject { |f| f =~ /^\./ }      result = file_list.map |file|       html = file.read("#{html_file_dir}/#{file}")       doc = nokogiri::html(html)       parse_to_hash(doc)     end     write_csv(result)   end    def self.parse_to_hash(doc)     array = []     array << doc.css(`your select conditons`).first.content     ... #add selector code css or xpath      array   end    def self.write_csv(result)     ::csv.open("`your out put file name`", 'w') |csv|       result.each { |row| csv << row }     end   end end  myparser.run

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
