Semalt: Come analizzare i dati dai siti Web utilizzando Dcsoup

Oggigiorno, estrarre informazioni da siti Web statici e di caricamento di JavaScript è diventato semplice come fare clic sul contenuto di cui hai bisogno da un sito. Gli strumenti di scraping Web realizzati con tecnologie euristiche sono stati proposti per aiutare i marketer, i blogger ei webmaster online a estrarre dal web dati semi-strutturati e non strutturati.

Web content extraction

Conosciuto anche come web scraping, l'estrazione di contenuti web è una tecnica per estrarre vaste serie di dati dai siti web. Quando si tratta di Internet e del marketing online, i dati sono una componente cruciale da considerare. I marketer finanziari e i consulenti di marketing dipendono dai dati per rintracciare le performance delle materie prime nei mercati azionari e sviluppare strategie di marketing.

Dcsoup HTML parser

Dcsoup è una libreria .NET di alta qualità utilizzata da blogger e webmaster per raschiare dati HTML da pagine Web. Questa libreria offre un'interfaccia API (Application Programming Interface) molto comoda e affidabile per manipolare ed estrarre i dati. Dcsoup è un parser Java HTML utilizzato per analizzare i dati da un sito Web e visualizzare i dati in formati leggibili.

Questo parser HTML utilizza Cascading Style Sheets (CSS), tecniche basate su jQuery e Document Object Model (DOM) per raschiare siti Web. Dcsoup è una libreria gratuita e facile da usare che offre risultati di scraping web coerenti e flessibili. Questo strumento di scraping web analizza l'HTML nello stesso DOM di Internet Explorer, Mozilla Firefox e Google Chrome.

Come funziona la libreria Dcsoup?

Dcsoup è stato progettato e sviluppato per creare un albero di analisi sensibile per tutte le varietà HTML. Questa libreria Java è la soluzione definitiva per raschiare dati HTML da fonti multiple e singole.

 Scollega il PC ed esegui le seguenti attività principali: 

  • Impedisci gli attacchi XSS pulendo il contenuto da una white-list coerente, flessibile e sicura.
  • Manipola il testo, gli attributi e gli elementi HTML.
  • Identifica, estrai e analizza i dati dal sito web utilizzando i selettori di traversal DOM e CSS ben gestiti.
  • Recupera e analizza i dati HTML in formati utilizzabili. È possibile esportare i dati raschiati su CouchDB. Foglio di calcolo di Microsoft Excel o salvare i dati sul computer locale come file locale.
  • Raschia e analizza sia i dati XML che HTML da un file, una stringa o un file.

Utilizzo del browser Chrome per ottenere XPath

Il raschiamento del web è una tecnica di gestione degli errori utilizzata per analizzare i dati HTML e analizzare i dati dai siti Web. È possibile utilizzare il browser Web per recuperare l'XPath dell'elemento di destinazione su una pagina Web. Ecco una guida passo-passo su come ottenere XPath di un elemento usando il tuo browser. Tuttavia, si noti che è necessario utilizzare tecniche di gestione degli errori poiché l'estrazione dei dati Web può causare errori se la formattazione originale della pagina cambia.

  • Aprire gli "Strumenti per sviluppatori" su Windows e selezionare l'elemento specifico per cui si desidera utilizzare XPath.
  • Fare clic con il tasto destro del mouse sull'elemento nella scheda "Elementi".
  • Fare clic sull'opzione "Copia" per ottenere l'XPath dell'elemento di destinazione.

Lo scraping Web consente di analizzare documenti HTML e XML. I web scrapers hanno utilizzato un software di scraping ben sviluppato per creare un albero di analisi per pagine analizzate che possono essere utilizzate per estrarre informazioni rilevanti dall'HTML. Nota che i dati raschiati dal web possono essere esportati in un foglio di calcolo di Microsoft Excel, CouchDB, o salvati in un file locale.
