Thanks - it was a version error, on my side, I think.

The tools.jar file comes with the JDK. It's in the ext directory I think.
It's probably a version issue - it's looking for an older version of the JDK
tools than you have.
You may be able to edit the build.xml and change the version.

Sorry if this is a FAQ, I couldn't see it mentinoed on the site.

Since using HTML Parser, I've been getting the following from Maven:
"Missing artifact com.sun:tools:jar:1.6.0:system"

I've tried adding the extra build profile mentioned on the Maven FAQ
page, to no avail.

Could someone please help?

I am going to do a project based on HtmlParser.  So as a first step i
suppose to learn the HtmlParser. I go through the documentation but it is
difficult keep track the context while learning through the documentation.
So could you please provide some tutorials of HtmlParser, so that i can
learn it well.. Thanks in advance..

You don't need a parser.
Just get the text directly:

URL url
URLConnection con;
InputStream in;

con = url.openConnection ();
con.connect ();
in = con.getInputStream()

then do what you want with the contents.

Hi Good Day,

I've been trying to look for a function in this library that can return a string of html text of a web page. I know the java.net.URLConnection can provide me with it, but it's better for me to just use a single function say getHTMLSource that returns the html text of a url.Please let me know if it's possible here and with sample code :) Thanks in advance,



Kind Regards,
nef

You probably want the text that you can get from the StringBean.
http://htmlparser.sourceforge.net/javadoc/index.html.

Or if you really want the tags too, you can use toHtml().

Dear Users,

I am quite new to this library. I want to use the function getStringText()  from CompositeParser class. I dont know how I can use it.  I am doing the following:

parser = new Parser (urlString);
NodeList list = new NodeList ();
NodeFilter filter = new TagNameFilter ("STRONG");

for (NodeIterator e = parser.elements (); e.hasMoreNodes ();)
		  (e.nextNode ()).collectInto (list, filter);


Can you help me for finding the way I can typecast or something to get getStringText() function work.


Thank you very much

Ashish

Good Day!

I just woke up,8:30 in the morning. I'm very glad got a reply from this organization already with very helpful information. I will look at this later this morning as I will have a seminar to attend to at university.

Thank you very much! i really appreciated this help :)

I will check on here from time to time if I get hung up on a problem regarding the topic.



Respectfully,
neftali

I am newbie to HTML parsing. I knew both Java and HTML well. I would like to
construct a DOM tree from the HTML coding of a Webpage. It would be helpful
for me if someone specify how to get started and kindly provide some
tutorial or article links. Provide Sample programs if possible.. Thanks in
advance..

Have a look at the mainline in Parser.java:
http://htmlparser.svn.sourceforge.net/viewvc/htmlparser/trunk/parser/src/main/java/org/htmlparser/Parser.java?revision=8&view=markup

That program prints it out, but the results of parser.Parse (filter) is a
NodeList which is your (nested) dom tree.

Also have a look for other main methods in the code.

Hi everyone.

I am Neftali Papelleras, an Engineering student from University of San Carlos, Cebu City, Philippines. I am currently having my thesis project which involves web crawling. The title of my project is A Web Extraction Tool to Monitor Websites and is implemented in Java. I am still on the first month of this one-year thesis project, and still on the information gathering stage.

The first question I need to answer is how to create a Java-based web crawler. And next is how to retrieve the the web contents on every web page. And lastly, how to retrieve links from a given web source. First thing came to my mind was to use Java RegEx to retrieve the links given a web source. But now I understand it's not the right way to do it. And that's why I came to HTML Parser, because I knew this is the right way.

I know Java but not on advanced level, I just know the concept. Though I have created several programs already, last was a chat system, I am still not confident with my skills on Java. But I am very much eager to learn and I am starting now, again.

I have already downloaded the 1.6 version of HTML Parser and have browsed on different folders and files. I attempted to create a very simple parser program using the HTML Parser API, but unfortunately I was confused where to and how to start. I am hoping that this organization can provide a simple program that illustrates how to retrieve a link given a  web page source/html text. I can follow through the program and eventually lead me to the understanding of using this API.

Looking forward for a good response from this organization.

Respectfully,
neftali

The first question I need to answer is how to create a Java-based web crawler. And next is how to retrieve the the web contents on every web page. And lastly, how to retrieve links from a given web source. First thing came to my mind was to use Java RegEx to retrieve the links given a web source. But now I understand it's not the right way to do it. And that's why I came to HTML Parser, because I knew this is the right way.

I know Java but not on advanced level, I just know the concept. Though I have created several programs already, last was a chat system, I am still not confident with my skills on Java. But I am very much eager to learn and I am starting now, again.

I have already downloaded the 1.6 version of HTML Parser and have browsed on different folders and files. I attempted to create a very simple parser program using the HTML Parser API, but unfortunately I was confused where to and how to start. I am hoping that this organization can provide a simple program that illustrates how to retrieve a link given a  web page source/html text. I can follow through the program and eventually lead me to the understanding of using this API.

Looking forward for a good response from this organization.

Respectfully,

Have a look at the mainline in Parser.java:
http://htmlparser.svn.sourceforge.net/viewvc/htmlparser/trunk/parser/src/main/java/org/htmlparser/Parser.java?revision=8&view=markup

That program prints it out, but the results of parser.Parse (filter) is a
NodeList which is your (nested) dom tree.

Also have a look for other main methods in the code.

I am newbie to HTML parsing. I knew both Java and HTML well. I would like to
construct a DOM tree from the HTML coding of a Webpage. It would be helpful
for me if someone specify how to get started and kindly provide some
tutorial or article links. Provide Sample programs if possible.. Thanks in
advance..
