Semalt: alles wat u moet weten over PHP Web Scraper als een HTML-scrapper

Dec 06, 2017

PHP Web Scraper helpt om HTML automatisch van webpagina's af te schrapen en weer te geven op verschillende websites. Wat deze applicatie uniek maakt, is dat deze gegevens van een bepaalde locatie haalt en deze ergens anders herhaaldelijk weergeeft. Dus terwijl de inhoud van de bronwebsite wordt bijgewerkt, schrapt het programma de inhoud en laat het deze zien op de bestemmingswebsite, waardoor de website ook wordt bijgewerkt.

Als u bijvoorbeeld voortdurend de nieuwste voetbalscores van een populaire website moet opvragen, voert u de URL van de bronwebpagina in die is gekoppeld aan een CSS-kiezer aan PHP-webschraper. Het zal een code genereren. U voegt nu de code in de broncode van uw pagina in en dat is het. Wat u op uw pagina zult vinden, is de laatste score op de bronpagina.

Deze tool is geweldig voor het extraheren van regelmatig bijgewerkte inhoud zoals rankings, aandelenkoersen, prijzen en nieuws om er maar een paar te noemen. Deze HTML-scraper is een van de beste omdat hij gemakkelijk te gebruiken is, hij biedt hoge prestaties, hij werkt met vrijwel alle browsers en vooral met kwaliteitsondersteuning.

Nadelen

Helaas kan de applicatie mogelijk geen gegevens van sommige sites extraheren. Het is dus raadzaam om het te proberen voordat je het koopt. Momenteel kan de scraper geen video's van Vimeo, YouTube en vele websites voor het delen van video's extraheren.

Het kan ook niet de inhoud van flash-bestanden grijpen, hoewel het de bestanden kan pakken. Het kan inhoud die alleen zichtbaar is voor geregistreerde gebruikers van sommige websites zoals de inbox en profielpagina van sommige van deze websites, niet ook pakken. Inhoud die door Angular.js, AJAX en enkele andere JavaScript-technieken wordt gegenereerd, kan niet met deze tool worden geëxtraheerd.

Schakel JavaScript in uw browser uit voordat u een webpagina schraapt en bezoek de webpagina. Alle inhoud die u nog steeds kunt zien nadat JavaScript is uitgeschakeld, is wat u van de pagina kunt extraheren. Het is ook belangrijk om in gedachten te houden dat HTML die afbeeldingen met relatieve paden bevat, niet op uw pagina wordt weergegeven.

Antwoorden op veelgestelde vragen

Met deze tool kunt u inhoud van verschillende pagina's extraheren en op één pagina weergeven. U hoeft alleen een code te genereren voor elk van de bronpagina's en deze in te voegen in de broncode van de pagina waarin u ze wilt weergeven.

Daarnaast is het mogelijk om verschillende elementen uit dezelfde bronpagina te extraheren.
Het is niet mogelijk om webpagina's met dit hulpmiddel te klonen, omdat dat niet de bedoeling is.
Hoewel deze toepassing WordPress niet ondersteunt, is er een afzonderlijke tool voor WordPress.
U kunt CSS gebruiken om de geëxtraheerde HTML te stijlen
U kunt JavaScript / jQuery gebruiken om de geëxtraheerde HTML aan te passen.
U kunt alleen de nieuwste HTML-gegevens ophalen door uw webpagina te vernieuwen. Als u het voorbeeld van de voetbalscore opnieuw gebruikt, als de laatste score die u zag 0 - 0 was en de score verandert in 1 - 0, zult u deze niet zien op uw webpagina totdat u hem hebt vernieuwd.
De geëxtraheerde HTML zal zonder HTML in HTML-formaat op uw webpagina verschijnen.

Concluderend wordt aanbevolen om deze tool op legitieme wijze te gebruiken. Zoek altijd de toestemming van de eigenaren van een webpagina voordat u HTML-inhoud erop pakt. U staat volledig alleen voor het gebruik van deze tool.
