Thread: [Htmlparser-user] Link Parsing within RemarkNode

I have a link that I would like to parse out of html code, but the link 
is located within a remark.  How can I parse out the contents of the 
"href" that is between the <!--  <a class="greylink" href="somecode"> 
-->

Thanks,

Ed

You can take the text from the Remark node and pass it into another parser:

NodeList remarks = parser.parse (new NodeClassFilter (Remark.class));

Parser parser = new Parser (); // you can't pass the string in the 
constructor... it wants a URL
... foreach remark node in the list
{
    String s = remarkNode.getText ();
    parser.setInputHTML (s);
    NodeList links = parser.parse (new TagNameFilter ("A"));
    // if there's at least one link...
    if (1 <= links.size ())
        LinkTag link = links.elementAt (0);
}

  // I wrote this code .My output is different from the output by running
the StringExtractor batch file.
 In my output i didnot get the carriage return(\n).can u suggest any remedy
for this?
  sextract =3D
new StringExtractor (url1);

PrintWriter out1 =3D
new PrintWriter (new FileOutputStream ("C:\\goo.txt"));

out1.println(sextract.extractStrings (
true));

out1.close();

sextract1 =3D
new StringExtractor ("c:\\goo.txt");

PrintWriter out11 =3D
new PrintWriter (new FileOutputStream ("C:\\goo1.txt"));

out11.println(sextract1.extractStrings (
true));

out11.close();

 can u suggest how to get the same output with my code?

plz reply me.....

Thanks!  This worked great.  Now I have another issue.  I want to parse 
the link that was just extracted.  The link now contains spaces in the 
string instead of %20.  This causes a parser exception.  Is there a way 
to covert the spaces to %20?

I think this may be what you're looking for. Hope it helps.

String encodedString = java.net.URLEncoder.encode("string you want to 
convert to UTF-8", "UTF-8");
