Semalt erklärt, wie man Daten mit Lxml und Requests kratzt

Wenn es um Content-Marketing geht, kann die Bedeutung von Web Scraping nicht sein ignoriert. Web Scraping ist auch als Web-Datenextraktion bekannt und ist eine Suchmaschinenoptimierungstechnik, die von Bloggern und Marketingberatern verwendet wird, um Daten von E-Commerce-Websites zu extrahieren. Website-Scraping ermöglicht es Vermarktern, Daten in nützlichen und komfortablen Formaten zu erhalten und zu speichern.

Die meisten E-Commerce-Websites werden üblicherweise in HTML-Formaten geschrieben, wobei jede Seite ein gut erhaltenes Dokument enthält. Das Auffinden von Websites, die ihre Daten in JSON- und CSV-Formaten bereitstellen, ist ein bisschen schwierig und kompliziert. Hier kommt Web-Daten-Extraktion ins Spiel. Ein Web-Scraper hilft Vermarkter, Daten aus mehreren oder einzelnen Quellen herauszuziehen und in benutzerfreundlichen Formaten zu speichern.

Rolle von lxml und Anfragen beim Data-Scraping

In der Marketingbranche wird lxml häufig von Bloggern und Webseitenbetreibern verwendet, um Daten schnell von verschiedenen Websites zu extrahieren. In den meisten Fällen extrahiert lxml Dokumente in HTML- und XML-Sprache. Webmaster verwenden Anfragen, um die Lesbarkeit von Daten zu verbessern, die von einem Webseiten-Scraper extrahiert wurden. Anforderungen erhöhen auch die Gesamtgeschwindigkeit, die von einem Scraper verwendet wird, um Daten aus einzelnen oder mehreren Quellen zu extrahieren..

Wie extrahiere ich Daten mit lxml und Anfragen?

Als Webmaster können Sie einfach lxml und Anfragen mit der Pip-Installationstechnik installieren. Verwenden Sie einfach verfügbare Daten zum Abrufen von Webseiten. Verwenden Sie nach dem Abrufen der Webseiten einen Webseiten-Scraper, um Daten mithilfe eines HTML-Moduls zu extrahieren und die Dateien in einem Baum zu speichern, der allgemein als Html.fromstring bekannt ist. Html.fromstring erwartet, dass Webmaster und Vermarkter Bytes als Eingabe verwenden, daher ist es ratsam, page.content tree anstelle von page.text zu verwenden.

Eine exzellente Baumstruktur ist von größter Bedeutung beim Parsen von Daten in Form eines HTML-Moduls. .. CSSSelect- und XPath-Wege werden meistens verwendet, um Informationen zu finden, die von einem Webseiten-Scraper extrahiert wurden. Webmaster und Blogger bestehen hauptsächlich darauf, XPath zu verwenden, um Informationen über gut strukturierte Dateien wie HTML- und XML-Dokumente zu finden.

Zu den empfohlenen Tools zum Auffinden von Informationen in HTML-Sprache gehören Chrome Inspector und Firebug. Für Webmaster, die Chrome Inspector verwenden, klicken Sie mit der rechten Maustaste auf das zu kopierende Element, wählen Sie "Element prüfen" aus, markieren Sie das Skript des Elements, klicken Sie erneut mit der rechten Maustaste und wählen Sie "XPath kopieren" aus.

Importieren von Daten mit Python

XPath ist ein Element, das hauptsächlich auf E-Commerce-Websites zum Analysieren von Produktbeschreibungen und Preisschildern verwendet wird. Daten, die mithilfe des Web-Scrapers von einer Website extrahiert wurden, können mithilfe von Python leicht interpretiert und in lesbaren Formaten gespeichert werden. Sie können die Daten auch in Tabellen oder Registrierungsdateien speichern und sie mit der Community und anderen Webmastern teilen.

In der aktuellen Marketingbranche ist die Qualität Ihrer Inhalte sehr wichtig. Python gibt Vermarkter die Möglichkeit, Daten in lesbare Formate zu importieren. Um mit Ihrer eigentlichen Projektanalyse zu beginnen, müssen Sie entscheiden, welchen Ansatz Sie verwenden möchten. Die extrahierten Daten sind in verschiedenen Formen verfügbar, von XML bis HTML. Schnelles Abrufen von Daten mit einem Web-Scraper und Anfragen mit den oben genannten Tipps
