Semalt legt uit hoe u gegevens kunt schrapen met Lxml en aanvragen

Op het gebied van inhoudmarketing kan het belang van webschrapen niet worden buiten beschouwing gelaten. Ook bekend als web data-extractie, web scraping is een zoekmachine optimalisatie techniek gebruikt door bloggers en marketing consultants om gegevens uit e-commerce websites te extraheren. Met scraping op de website kunnen marketeers gegevens in handige en comfortabele indelingen verkrijgen en opslaan.

De meeste e-commerce websites worden gewoonlijk in HTML-indeling geschreven, waarbij elke pagina een goed bewaard document bevat. Het vinden van sites die hun gegevens in JSON- en CSV-indelingen aanbieden, is een beetje moeilijk en gecompliceerd. Dit is waar de extractie van webgegevens binnenkomt. Een scraper voor webpagina's helpt marketeers om gegevens uit meerdere of afzonderlijke bronnen te halen en op te slaan in gebruiksvriendelijke indelingen.

De rol van lxml en verzoeken om gegevens te schrapen

In de marketingindustrie wordt lxml vaak gebruikt door bloggers en website-eigenaren om snel gegevens van verschillende websites te extraheren. In de meeste gevallen extraheert lxml documenten geschreven in HTML- en XML-talen. Webmasters gebruiken verzoeken om de leesbaarheid van gegevens die door een webpaginaschraper worden geëxtraheerd, te verbeteren. Verzoeken verhogen ook de algehele snelheid die door een schraper wordt gebruikt om gegevens uit enkele of meerdere bronnen te extraheren.

Hoe gegevens extraheren met lxml en verzoeken?

Als webmaster kunt u gemakkelijk lxml en verzoeken installeren met behulp van de pip install-techniek. Gebruik direct beschikbare gegevens om webpagina's op te halen. Nadat u de webpagina's hebt verkregen, gebruikt u een schraper voor een webpagina om gegevens te extraheren met behulp van een HTML-module en slaat u de bestanden op in een structuur, beter bekend als Html.fromstring. Html.fromstring verwacht dat webmasters en marketeers bytes als input gebruiken en daarom is het raadzaam om de paginacontentboom te gebruiken in plaats van page.text

Een uitstekende boomstructuur is van het grootste belang bij het parseren van gegevens in de vorm van een HTML-module . CSSSelect- en XPath-manieren worden meestal gebruikt om informatie te vinden die wordt geëxtraheerd door een schraper op de webpagina. Vooral webmasters en bloggers staan erop XPath te gebruiken om informatie te vinden over goed gestructureerde bestanden zoals HTML- en XML-documenten.

Andere aanbevolen hulpmiddelen voor het lokaliseren van informatie met behulp van HTML-taal omvatten Chrome Inspector en Firebug. Voor webmasters die Chrome Inspector gebruiken, klikt u met de rechtermuisknop op het element dat moet worden gekopieerd, selecteert u de optie 'Inspecteer element', markeert u het script van het element, klikt u met de rechtermuisknop op het element en selecteert u op 'XPath kopiëren'.

Gegevens importeren met python

XPath is een element dat vooral wordt gebruikt op e-commerce websites om productbeschrijvingen en prijskaartjes te analyseren. Gegevens die zijn geëxtraheerd van een site met de webpaginaschraper, kunnen eenvoudig worden geïnterpreteerd met Python en worden opgeslagen in door mensen leesbare indelingen. U kunt de gegevens ook opslaan in werkbladen of registerbestanden en deze delen met de community en andere webmasters.

In de huidige marketingsector is de kwaliteit van uw inhoud van groot belang. Python biedt marketeers de mogelijkheid om gegevens in leesbare formaten te importeren. Om aan de slag te gaan met uw daadwerkelijke projectanalyse, moet u beslissen welke aanpak u wilt gebruiken. Geëxtraheerde gegevens zijn er in verschillende vormen, variërend van XML tot HTML. Haal snel gegevens op met een schraper voor webpagina's en verzoeken met behulp van de hierboven besproken tips.
