Cannot fetch image Url (defined with data-original) inside specic class ( JSOUP)

问题

HTML source (Note that it uses lazy load jQuery plugin):

1). When I run code below it fetches all image Urls from website:

    Elements images=document.select("img[src~=(?i)\\.(png|jpe?g|gif)]");

2). But when I specify the class it fails, like below:

    Elements images=document.select("div.newscat img[src~=(?i)\\.(png|jpe?g|gif)]");

And then I employ ( in second case it throws OutOfBoundsException):

for (int i=0;i<images.size();i++){
  imageUrl[i]=images.get(i).attr("src");
}

Could, anyhow, lazy load be problem, if yes, How to solve?

回答1:

Finally , thanks to android: how can i scrap images (in url ) using jsoup?(Image tag contain attribute "data-original" which is url of image)

I found work around changing

Elements images=document.select("div.newscat img[src~=(?i)\\.(png|jpe?g|gif)]");
for (int i=0;i<images.size();i++){
  imageUrl[i]=images.get(i).attr("src");
}

to

Elements images=document.select("div.newscat").select("img");
for (int i=0;i<images.size();i++){
  imageUrl[i]=images.get(i).attr("data-original");
}
