Question

I want get all images using html parsing with jsoup. I use below code ;

Elements images = doc.select("img[src~=(?i)\\.(jpe?g)]");
        for (Element image : images) {

            //System.out.println("\nsrc : " + image.attr("src"));
            arrImageItem.add(image.attr("src"));

        }

I parse this method all images but i want to parse this url

http://tvrehberi.hurriyet.com.tr/images/742/403742.jpg

I want to parse beginnig of this url

http://tvrehberi.hurriyet.com.tr/images .... .jpg

How to get parse like this ?

Answer 1

This will probably give you what you ask for, though your question is a bit unclear, so I can't be sure.

public static void main(String args[]){

    Document doc = null;
    String url = "http://tvrehberi.hurriyet.com.tr";
    try {
        doc = Jsoup.connect(url).get();
    } catch (IOException e1) {
        e1.printStackTrace();
    }

    for (Element e : doc.select("img[src~=(?i)\\.(jpe?g)]")) {
        if(e.attr("src").startsWith("http://tvrehberi.hurriyet.com.tr/images")){
            System.out.println(e.attr("src"));
        }
    }
}

So, this might not be a very "clean" solution, but the if-statement will make sure it only prints out the image URL's from the /images/-directory on the server.

If I understood correctly, you want to retrieve the URL path up to a certain point and cut off the rest. Do you even have to do that every time? If you are only using URLs from the one site in your example, you could store "http://tvrehberi.hurriyet.com.tr/images" as a constant since it never changes. If, on the other hand, you fetch URLs from many different sites, you can parse your URL as described here .
Anyway, if you shared the purpose of parsing the URLs, we certainly could help you more.
