Wilt u meer weten over HTML-scraping? - Vraag het aan Semalt!

Dec 11, 2017

Websites en blogs zijn geschreven met behulp van HTML; het betekent dat elke webpagina het gestructureerde document is met daarin verschillende HTML-codes. Soms is het eenvoudig om gegevens van een website te extraheren of te schrapen en deze in een gestructureerde vorm op te slaan, en soms moeten we deze of gene HTML-scraptool gebruiken. Websites en blogs bieden niet altijd gegevens in CSV- en JSON-indelingen en daarom moeten we een HTML-scraper gebruiken. Met deze techniek verwerken verschillende softwaretools webpagina's om goed gestructureerde en georganiseerde gegevens te krijgen, waardoor we veel tijd en geld besparen.

Kenmerken van HTML-scraping:

Er zijn verschillende benaderingen voor HTML-scraping of gegevensextractie op de markten en HTML-scraping is een van de meest prominente. De onderscheidende eigenschappen of kenmerken worden hieronder genoemd.

1. Schraap een enorme hoeveelheid gegevens uit verschillende inhoudbeheersystemen:

Het beste deel van HTML-scraping is dat u een groot aantal WordPress-sites kunt schrapen. Zelfs wanneer een site is ontwikkeld op een ander contentbeheersysteem, hebt u toegang tot die gegevens en kunt u deze schrapen met een HTML-scraper.

2. Structuur en organiseer de gegevens:

HTML-scraping is een favoriete techniek geworden van webmasters, programmeurs en webontwikkelaars. Ze gebruiken deze methode om opgehaalde informatie te organiseren en op te slaan in een begrijpelijk formaat voor verder gebruik.

3. Het ondersteunt verschillende formaten:

Hoewel de geëxtraheerde gegevens altijd worden opgeslagen in de spreadsheet- of database-indelingen, is het interessant dat een HTML-schraap uw gegevens kan opslaan in zijn eigen database of cloudopslagapparaat. Dit type service werkt op webgebaseerde browsers en extraheert alleen gegevens van zware sites. Het schraapt en organiseert zowel tekst als afbeeldingen voor de gebruikers.

4. Goed voor advertenties en andere items:

Een HTML-krabber kan gegevens ophalen uit de gerubriceerde advertenties, gele pagina's , directories, e-commerce sites en privé-blogs handig. Een andere ongelooflijke bron van informatie is sociale media; het HTML-scrapen omvat het schrapen van sociale media en datamining ter overweging.

5. Geweldig voor Twitter-gebruikers:

Er zijn meer dan 300 actieve gebruikers op Twitter, en het is niet mogelijk voor een gewone schraper om alle gegevens van deze te schrapen sociale netwerk site. Een HTML-scraper kan deze functie echter voor u uitvoeren en kan de enorme hoeveelheid informatie schrapen in de vorm van afbeeldingen en tweets.

6. Het communiceert met webservers:

De HTML-scraping-software werkt op dezelfde manier samen met de webservers als de standaardwebpagina's en ontvangt informatie en query-aanvragen de hele dag. In plaats van de gegevens op een scherm weer te geven, slaat de HTML-scraper uw informatie op in het lokale opslagapparaat of de database voor later gebruik.

Concluderen:

Het is duidelijk dat HTML-scrapers verschillende webpagina's strategisch kunnen bewerken en schrapen, zodat u in een korte tijd de best mogelijke kwaliteit krijgt. Zonder dit kunt u geen inzicht krijgen in gigantische websites en uw bedrijf niet laten groeien op internet. Daarom moet u altijd investeren in een HTML-scraper die binnen enkele seconden of minuten de gewenste resultaten belooft.
