I am trying to web scrape the website savevideo.tube using JSOUP.
When we put a link in the search bar and click the search button, the website dynamically loads and shows some download links that I want to scrape. My problem is how to load link in JSOUP with the link search without clicking the search button and showing the results (scraping the results).
Is there any way to search for a link and load it without clicking any button and get results?
I tried this code but I'm not getting the required result.
val result:Document = Jsoup.connect(Constants.BASE_URL)
.data("url", Constants.YOUTUBE_LINK)
.data("sid", "9823478982349872384789273489238904790234")
.userAgent("Mozilla").post()
JSOUP is a Static HTML parser. You cannot parse the content that is loaded by javascript dynamically. For that, you have to use a web drive.
The best web drives that you can use are
HTML Unit
JBrowserDriver
You can also use selenium but it may not be ideal for android
:-
As mentioned by ʀᴀʜɪʟ, JSOUP is a static HTML parser only. If you want to scrape a website that uses JS generated content you should probably take a look at skrape.it library
fun getDocumentByUrl(urlToScrape: String) = skrape(BrowserFetcher) { // <--- pass BrowserFetcher to include rendered JS
request { url = urlToScrape }
response { htmlDocument { this } }
}
fun main() {
// do stuff with the document
}

I am new to java and using a jaunt1.3.8 library for web scraping.
I am trying to get the InnerHTML of the webpage : https://www.justdial.com/Pune/Cake-Shops/nct-10070075.
the site will not show us the full list of search results.
when we reach the bottom of the page it will load again.
it will stop loading after 10 scrolls.
I want to scrap the data of this dynamic loading webpage using the jaunt1.3.8 library but I don't know how to do it.
This is your first page: https://www.justdial.com/Pune/Cake-Shops/nct-10070075/page-1
PagniaE = "https://www.justdial.com/Pune/Cake-Shops/nct-10070075/page-1";
Make a loop:
while (IniPag<=100) {
userAgent.visit(PaginaE);
// (do someting)...
PaginaE = PaginaE.replace("page1","page2"); //Dynamic
}
I'm using Jsoup to scrape some online data from different stores, but I'm having trouble figuring out how to programmatically replicate what I do as a user. To get the data manually (after logging in), a user must select a store from a tree that pops up.
As best I can tell, the tree is not hard-coded into the site but is built interactively when your computer interacts with the server. When you look for the table in "view page source," there are no entries. When I inspect the tree, I do see the HTML and it seems to come from the "FancyTree" plugin.
As best as I can tell from tracking my activity on Developer Tools -- Network, the next step is a "GET" request which doesn't change the URL, so I'm not sure how my store selection is being transferred.
Any advice on how to get Jsoup or Java generally to programmatically interact with this table would be extremely helpful, thank you!
Jsoup can only parse the original source file, not the DOM. In order to parse the DOM, you'll need to render the page with something like HtmlUnit. Then you can parse the html content with Jsoup.
// load page using HTML Unit and fire scripts
WebClient webClient = new WebClient();
HtmlPage myPage = webClient.getPage(myURL);
// convert page to generated HTML and convert to document
doc = Jsoup.parse(myPage.asXml());
// do something with html content
System.out.println(doc.html());
// clean up resources
webClient.close();
See Parsing Javascript Generated Page with Jsoup.
I have the following code:
doc = Jsoup.connect("http://www.amazon.com/gp/goldbox").userAgent("Mozilla").timeout(5000).get();
Elements hrefs = doc.select("div.a-row.layer");
System.out.println("Results:"+ hrefs); //I am trying to print out contents but not able to see the output.
Problem: Want to display all image src within the div with class name "a-row layer". But, i am unable to see the output.
What is the mistake with my query?
I have taken a look at the website and tested it myself. The issue seems to be that the piece of html code you want to extract (div.a-row.layer) is generated by JavaScript.
Jsoup does not support JavaScript and cannot parse those generated by it. You would need a headless web browser to deal with this, such as HTMLUnit.
I am trying to Jsoup to parse the html from the URL http://www.threadflip.com/shop/search/john%20hardy
Jsoup looks to only get the data from the line
<![CDATA[ window.gon= ..............
Does anyone know why this would be?
Document doc = Jsoup.connect("http://www.threadflip.com/shop/search/john%20hardy").get();
The site you try to parse loads most of its contents async via AJAX calls. JSoup does not interpret Javascript and therefore does not act like a browser. It seems that the store is filled by calling their api:
http://www.threadflip.com/api/v3/items?attribution%5Bapp%5D=web&item_collection_id=&q=john+hardy&page=1&page_size=30
So maybe you need to directly load the API Url in order to read the stuff you want. Note that the response is JSON, not HTML, so the JSoup html parser is of not much help here. But there is great JSON libraries available. I use JSON-Simple.
Alternatively, you may switch to Selenium webdriver, which actually remote controls a real browser. This should have no trouble accessing all items from the page.
The problem is that some of the urls I am trying to pull from have javascript slideshow containers that haven't loaded yet. I want to get the images in the slideshow but since this hasn't loaded yet it doesn't grab the element. Is there anyway to do this? This is what I have so far
Document doc = Jsoup.connect("http://news.nationalgeographic.com/news/2013/03/pictures/130316-gastric-brooding-frog-animals-weird-science-extinction-tedx/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+ng%2FNews%2FNews_Main+%28National+Geographic+News+-+Main%29").get();
Elements jpg = doc.select("img[src$=.jpg]");
jsoup can't handle javascript, but you can use an additional library for this:
