    <p>I would like to make a program that parses the html page and selects useful information and displays it. I did it by opening a stream and then line by line searching for this appropriate content, but this is a time consuming process. So then I decided to do it by treating it as a xml and then using xpath. This I did by making a xml file on my system and loading the contents from the stream, and I got white space error, then I decide to direct open document as</p> <pre><code>doc = (Document) builder.parse(inputStream); </code></pre> <p>but the same error still persists. After asking here I was suggested to use jSoup for html parsing, now when I execute my code for:</p> <pre><code>Document doc= Jsoup.connect(url).get(); </code></pre> <p>I get Read timed out. The same program when made in python and using a naive strategy like using find method of string and searching, I am displayed the contents and that too fast. How to make it work fast in java?</p> <p>Complete code:</p> <pre><code>import java.io.*; import org.jsoup.Jsoup; import org.jsoup.helper.Validate; import org.jsoup.nodes.Document; import org.jsoup.nodes.Element; import org.jsoup.select.Elements; public class Parser { public static void main(String[] args) { Validate.isTrue(true, "usage: supply url to fetch"); try{ String url="http://www.spoj.com/ranks/PRIME1/"; Document doc= Jsoup.connect(url).get(); Elements es=doc.getElementsByAttributeValue("class","lightrow"); System.out.println(es.get(0).child(0).text()); }catch(Exception e){e.printStackTrace();} } </code></pre> <p>}</p> <p>Exception:</p> <pre><code>java.net.SocketTimeoutException: Read timed out at java.net.SocketInputStream.socketRead0(Native Method) at java.net.SocketInputStream.read(Unknown Source) at java.net.SocketInputStream.read(Unknown Source) at java.io.BufferedInputStream.fill(Unknown Source) at java.io.BufferedInputStream.read1(Unknown Source) at java.io.BufferedInputStream.read(Unknown Source) at sun.net.www.http.HttpClient.parseHTTPHeader(Unknown Source) at sun.net.www.http.HttpClient.parseHTTP(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source) at java.net.HttpURLConnection.getResponseCode(Unknown Source) at org.jsoup.helper.HttpConnection$Response.execute(HttpConnection.java:412) at org.jsoup.helper.HttpConnection$Response.execute(HttpConnection.java:393) at org.jsoup.helper.HttpConnection.execute(HttpConnection.java:159) at org.jsoup.helper.HttpConnection.get(HttpConnection.java:148) at Parser.main(Parser.java:12) </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
