Jsoup get href within a class - java

I have this html code that I need to parse
<a class="sushi-restaurant" href="/greatSushi">Best Sushi in town</a>
I know there's an example for jsoup that you can get all links in a page,e.g.
Elements links = doc.select("a[href]");
for (Element link : links) {
print(" * a: <%s> (%s)", link.attr("abs:href"),
trim(link.text(), 35));
}
but I need a piece of code that can return me the href for that specific class.
Thanks guys


You can select elements by class. This example finds elements with the class sushi-restaurant, then gets the absolute URL of the first result.
Make sure that when you parse the HTML, you specify the base URL (where the document was fetched from) to allow jsoup to determine what the absolute URL of a link is.
public static void main(String[] args) {
String html = "<a class=\"sushi-restaurant\" href=\"/greatSushi\">Best Sushi in town</a>";
Document doc = Jsoup.parse(html, "http://example.com/");
// find all <a class="sushi-restaurant">...
Elements links = doc.select("a.sushi-restaurant");
Element link = links.first();
// 'abs:' makes "/greatsushi" = "http://example.com/greatsushi":
String url = link.attr("abs:href");
System.out.println("url = " + url);
}
Shorter version:
String url = doc.select("a.sushi-restaurant").first().attr("abs:href");
Hope this helps!


Elements links = doc.select("a");
for (Element link : links) {
String attribute=link.attr("class");
if(attribute.equalsIgnoreCase("sushi-place")){
print link.href//You probably need this
}
}

jsoup extract specific attribute from a hyperlink

I have I some hyperlinks in a web page that I want to extract the attribute title which within it
I tried
select("a[href]").attr("title")
but I get no thing
Edit
The complete div here
Trial code
Elements es = doc.select("div.mini-placard")
for(Element e:es)
{
System.out.println( e.select("span.align-image-vertically").select("a").attr("title"));
}
no output !

Please extract link element properly and then inspect attributes of the link element as below:
String html = "<p>An <a href='http://example.com/' title='hi'><b>example</b></a> link.</p>";
Document doc = Jsoup.parse(html);
Element link = doc.select("a").first();
String text = doc.body().text(); // "An example link"
String linkHref = link.attr("href"); // "http://example.com/"
String linkTitle = link.attr("title"); // 'hi'

Extracting multiple links within a specific class

<div class="customer"><a href='view.php?customer=1234' class=''></div>
<div class="customer"><a href='view.php?customer=1235' class=''></div>
<div class="customer"><a href='view.php?customer=1236' class=''></div>
In this example, would there be any way to extract the href links within the customer class, without having to re-parse the html?

Unless there is a better way, I think this works...
Elements links = doc.select("div.customer a[href]");
String absHref;
for (Element link : links) {
absHref = link.attr("abs:href");
System.out.println(absHref);
}

Elements customerElements = doc.getElementsByTag("cutomer");
for(Element cutomer:customerElements){
String link =customer.getElementsByTag("a").first().attr("href");
}

You can do it using the below code.
Elements links = doc.select("div.customer a");
String linkUrl;
for (Element link : links) {
linkUrl = link.attr("href");
System.out.println(linkUrl);
}

java jsoup parse how to parse html

Is there any possible way to parse
Huhi
in html:
Huhi
White
Angle
Output:
Huhi
White
Angle

Create your document and get all the a[href] links, iterate through these links and get the text they contain. Like so:
Document doc = Jsoup.connect(url).get();
Elements links = doc.select("a[href]");
for (Element link : links) {
String text = link.text();
}

You just select a and iterate the elements and print
String html ="Huhi\n" +
"White\n" +
"Angle";
Document doc = Jsoup.parse(html);
Elements links = doc.select("a");
for (Element link : links) {
System.out.println(link.text());
}

Parse the inner html tags using jSoup

I want to find the important links in a site using Jsoup library. So for this suppose we have following code:
<h1>This is important </h1>
Now while parsing how can we find that the tag a is inside the h1 tag?

You can do it this way:
File input = new File("/tmp/input.html");
Document doc = Jsoup.parse(input, "UTF-8", "http://example.com/");
Elements headlinesCat1 = doc.getElementsByTag("h1");
for (Element headline : headlinesCat1) {
Elements importantLinks = headline.getElementsByTag("a");
for (Element link : importantLinks) {
String linkHref = link.attr("href");
String linkText = link.text();
System.out.println(linkHref);
}
}
Taken from the JSoup Cookbook.

Use selector:
Elements elements = doc.select("h1 > a");

Extracting user details from facebook page

I am extracting details from a page which I'm administering. I tried using jsoup to extract the links then from that extract names of users but it's not working. It only shows links other than user links. I tried extracting names from this link
https://www.facebook.com/plugins/fan.php?connections=100&id=pageid
which is working quite well but does not works for this link
https://www.facebook.com/browse/?type=page_fans&page_id=
Can anyone help me...Below is the code which I tried.
doc = Jsoup.connect("https://www.facebook.com/browse/?type=page_fans&page_id=mypageid").get();
Elements els = doc.getElementsByClass("fsl fwb fcb");
Elements link = doc.select("a[href]");
for(Element ele : link)
{
system.out.println(ele.attr("href"));
} }

Try This
Document doc = Jsoup.connect("https://www.facebook.com/plugins/fan.php?connections=100&id=pageid").timeout(0).get();
Elements nameLinks = doc.getElementsByClass("link");
for (Element users : nameLinks) {
String name = users.attr("title");
String url = users.attr("href");
System.out.println(name + "-" + url);
}
It will give all the users name and URl present on the first link defined in your question.
