Esperto di Semalt: analisi web semplice come ABC

Tutti hanno affrontato la situazione quando è necessario raccogliere e sistematizzare una grande quantità di informazioni . Per le attività standard ci sono servizi già pronti, ma cosa succede se l'attività non è banale e non ci sono soluzioni pronte? Ci sono due modi: fare tutto manualmente e perdere un sacco di tempo o automatizzare il processo di routine e ottenere il risultato molte volte più velocemente. La seconda opzione è ovviamente più preferibile, quindi vi forniremo alcune informazioni sui parser web.

Come funziona un parser Web?

Indipendentemente dal linguaggio di programmazione in cui è scritto il parser web, l'algoritmo delle sue operazioni rimane lo stesso:

1. Accesso a Internet, raggiungendo il codice di un risorsa web e scaricandolo.

2. Lettura, estrazione ed elaborazione dei dati.

3. Presentazione dei dati estratti in forma utilizzabile: .txt, .sql, .xml, .html e altri formati.

Naturalmente, i parser web non leggono effettivamente il testo, semplicemente confrontano il set di parole proposto con quello che hanno trovato su Internet e agiscono secondo un determinato programma. Che cosa fa il parser con il contenuto che trova è scritto nella riga di comando che contiene un insieme di lettere, parole, espressioni e segni della sintassi del programma.

Web Parsers On PHP

PHP è molto utile per la creazione di parser web - ha una libreria incorporata libcurl che collega lo script a qualsiasi tipo di server, inclusi quelli che lavorano con i protocolli https ( connessione criptata), ftp, telnet. PHP supporta le espressioni regolari, attraverso le quali il parser web elabora i dati. Ha una libreria DOM per XML, un linguaggio di markup estensibile che di solito presenta i risultati del lavoro del parser web. PHP va d'accordo con HTML perché è stato creato per la sua generazione automatica.

Web Parsers On Python

Anche se diversamente da PHP, il linguaggio di programmazione Python è uno strumento generico (non solo uno strumento di sviluppo per Web), gestisce l'analisi in modo eccellente. Il motivo è un'alta qualità della lingua stessa.

La sintassi di Python è semplice, chiara, contribuisce a soluzioni ovvie di compiti spesso non ovvi. Di conseguenza, con questo linguaggio sono state create molte librerie consolidate per l'analisi web.

Pyparsing

Le espressioni regolari vengono utilizzate per l'analisi. C'è un modulo Python chiamato re per questo scopo, ma se non hai mai lavorato con le espressioni regolari, potrebbero confondervi. Fortunatamente, esiste un comodo strumento di analisi chiamato Pyparsing. Il suo vantaggio principale è che rende il codice più leggibile e consente di eseguire un'ulteriore elaborazione del testo analizzato.

Beautiful Soup

Beautiful Soup è una scritta sul parser web Python per l'analisi sintattica di file HTML / XML in grado di convertire anche un markup errato in un albero di analisi. Supporta i modi semplici e naturali di navigare, cercare e modificare l'albero di analisi. Nella maggior parte dei casi, aiuterà a risparmiare ore e persino giorni di lavoro.

Conclusion

Hai imparato alcune informazioni di base sui parser web e due linguaggi di programmazione più utili per creare e usare un parser web e alcune librerie che ti torneranno utili. Naturalmente, ci sono molte altre opzioni per l'analisi web, ma questi esempi possono aiutarti a iniziare.
