How to extract those elements in Jsoup - java

I want to extract the "Abstract" and the "Title" as shown in the photo below. However I can't extract the title and I tried to extract the tag "Abstract" but it didn't work.
String html = "http://example.com/";
Document doc = Jsoup.parse(html);
Element link = doc.select("Abstract").first();

Try this:
Element title = doc.select("FONT[size=+1]").first();
Element abstractParagraph = doc.select("CENTER:has(b:containsOwn(Abstract)) + p").first();

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'

Jsoup don't parse xml correctly, missing tags

I want to parse a xml text but jsoup seems to delete <col> tags.
This is what happens:
Original:
<rowh> <col>DTC Code</col> <col>Description</col> </rowh>
Result:
<rowh> DTC Code Description
</rowh>
This is the code I am using to see the content.
Document jDoc = Jsoup.parse(contentXML);
Log.d("Original", contentXML);
Log.d("Document", jDoc.outerHtml());
I need to count how many <col> tags are inside each <rowh> tag but it always returns 0. I am using Jsoup version 1.11.2
May this helps you:
String html = "<?xml version=\\\"1.0\\\" encoding=\\\"UTF-8\\\"><rowh><col>DTC Code</col><col>Description</col></rowh></xml>";
Document doc = Jsoup.parse(html, "", Parser.xmlParser());
Elements e = doc.select("rowh");
String text = e.text();
Log.i("TAG1", text);

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");

How to extract absolute URL from relative HTML links using Jsoup?

I am using Jsoup to extract URL of an webpage. The href attribute of those URL's are relative like:
example
Here is my attempt:
Document document = Jsoup.connect(url).get();
Elements results = document.select("div.results");
Elements dls = results.select("dl");
for (Element dl : dls) {
String url = dl.select("a").attr("href");
}
This works fine, but if I use
String url = dl.select("a").attr("abs:href");
to get the absolute URL like http://example.com/text, it is not working. How can I get the absolute URL?
You need Element#absUrl().
String url = dl.select("a").absUrl("href");
You can by the way shorten the select:
Document document = Jsoup.connect(url).get();
Elements links = document.select("div.results dl a");
for (Element link : links) {
String url = link.absUrl("href");
}
String url = dl.select("a").absUrl("href");
Is not correct because dl.select("a") will not return a single item but a collection.
You need to get elements by index
eg :
Elements elems = dl.select("a");
Element a1 = elems.get(0); //0 is the index first element increasing to (elems.size()-1)
now you can do
a1.absUrl("href");
If you are sure only one item will result from the select above, or that the item you want will be the first, you can:
String url = dl.select("a").get(0).absUrl("href");
Which is also same as
String url = dl.select("a").first().absUrl("href");
It doesn't have to be the first element anyway, you can always replace the 0 in
String url = dl.select("a").get(0).absUrl("href"); with the index of your element.
Or use a select that is more specific that will only result in one element.
