Read URL Using java.net.URL
This example shows how to display HTML text from the first paragraph on the www.mathworks.com website.
Construct URL Object
Call a java.net.URL constructor to create object url pointing to the MathWorks website.
url = java.net.URL('http://www.mathworks.com');
Open Connection to URL
Call the openStream method to establish a connection with the website. The method creates an InputStream object is for reading bytes from the site.
is = openStream(url);
Set Up Buffered Stream Reader
Create a buffered stream reader isr for reading characters using the java.io.InputStreamReader constructor. Create a buffered reader object br for efficient reading of characters, arrays, and lines.
isr = java.io.InputStreamReader(is); br = java.io.BufferedReader(isr);
Read Lines of Text
Read lines of HTML text from the website which are within the first paragraph tag '<p>'. The BufferedReader method readLine reads a line of text which is terminated by a carriage return and/or line feed character.
p1 = java.lang.String('<p>'); p2 = java.lang.String('</p>'); s = readLine(br); while ~(s.startsWith(p1)) s = readLine(br); end
