Hi,
Thanks for your response. I tried this code below in an attempt to see if it
would work given your comment:
StringBuffer finalContents = new StringBuffer();
//Generate final output
for (NodeIterator e = list.elements (); e.hasMoreNodes (); ) {
Node node = e.nextNode ();
if ( node.getEndPosition() == node.getStartPosition() ) {
log.debug ( " IGNORED node : " + node.toHtml());
continue;
}
if (node instanceof TagNode) {
if ( ((TagNode)node).getTagEnd() == ((TagNode)node). getTagBegin() )
{
log.debug ( " IGNORED node : " + node.toHtml());
continue;
}
}
finalContents.append(node.toHtml());
}
This didn't seem to make any different. The positions of the virtual tags
must've been corrected at an earlier stage in htmlparser. I have started
looking at the htmlparser source to see where this occurs.
Kind Regards,
Mark

Subject: Re: [Htmlparser-user] Parsing malformed HTML whilst still leaving
it intact
This has been a requested task for two years now:
http://sourceforge.net/pm/task.php?group_project_id=21601&group_id=24399&fun
c=browse
The virtual tags that are added have the start position the same as the
end position, so a smarter toHtml() could recognize them that way and
avoid outputting them.

Greetings. I am new to HTML. I need to login to an https webpage via a script. I have got as far as using HTMLParser to get the webpage, then POST to back to it with the received cookie and the four input fields required. (Two of the fields were hidden variables.) However, login is not working since I just get back the same initial webpage. Is it possible to use HTMLParser for https connections? Regards, Lori |

Hi, I'm parsing snippets of HTML pages at a time, making some changes and then outputting back to HTML. The problem with HTML snippets is that they will be malformed since some closing tags, for example, will be missing. The Parser seems to automatically correct the malformed HTML by adding closing tags. Is it possible to prevent it from doing so? Or at least it can notify me when it does so, so that before reconstructing the modified HTML output I can simply delete them. An alternative would be to use the Lexer but then I loose all the hierarchical features of the Parser, which not an option. This is similar to the general problem brought up in <http://sourceforge.net/mailarchive/message.php?msg_id=12635550> http://sourceforge.net/mailarchive/message.php?msg_id=12635550 . Kind Regards Mark |

The recursive extract should get *all" nodes matching the filter in a
flattened list.
That is, there may be parents and their children all in the same
NodeList... you have to traverse the parent child relations to find out
which is which.

The filter isn't going to re-arrange your page for you.
The best you can do is get the list of tags and then remove them from
their parent's child list:
for (int i=0; i < arr.length; i++)
{
filter1 = new TagNameFilter (arr[i]);
filter2 = new NotFilter (filter1);
NodeList x = n.extractAllNodesThatMatch (filter2);
for (int j = 0; j < x.Length; j++)
{
Node tag = x.elementAt (j);
tag.getParent ().getChildren ().remove (tag);
}
}
or something like that. No guarantees about removing something that's
already been removed though.

hi,
my name is srikrishna,i am a college student.
i am quiet new to html parser.
i am trying to use html parser to filter out certain tags in a html page.
with not filter i am able take out tags like script,img.
but the problem is that the tags are removed only if they outside any other
tags.
eg:if there is an img tag inside an table or td tag,the img tag is not
removed.
i dont want to remove the table or td tag,but i want to remove the
img,script tags inside the table tags.
the initial code i wrote was:
String[]arr=3Dnew
String[]{"img","input","br","span","script","noscript","b","a href",};
try{
Parser parser =3D new Parser ();
parser.setURL ("targetin.html");
NodeList n =3D parser.parse(null);
NodeFilter filter1 =3D null;
NotFilter filter2 =3D null;
for(int i=3D0;i<arr.length;i++){
filter1 =3D new TagNameFilter (arr[i]);
filter2 =3D new NotFilter(filter1);
n =3D n.extractAllNodesThatMatch(filter2);
}
String s1=3Dn.toHtml();
This code removes all tags,outside table,tr,td tags.but if they are inside
a table tag,it is not able to do it.

Gather all the nodes into a list using no filter:
NodeList all_nodes = parser.parse (null);
Then use the table filter on the whole list, process the nodes, and then
turn it back into a string:
NodeList tables = all_nodes.extractAllNodesThatMatch (all_tables);
... process the tables list...
System.out.println (all_nodes.toHtml ());

By the way, after this call:
NodeList list = parser.parse (all_tables);
the parser will be at the end of the page and return no more nodes.
So, this:
// Seperate all table tags
* for* (NodeIterator e = parser.elements ();
e.hasMoreNodes ();)
e.nextNode ().collectInto (list,all_tables);
doesn't do anything.
You can use:
parser.reset ();
to start again, if that is what you really want to do, but in your case
you would get duplicates of everything.

Hi All!
I want to change several attributes of the td and tr tags of certain =
tables but I don't know if do it the right way.
The problem is that I find the right table (only tables with ids) but I =
don't reach the td or tr tags....
My code looks like that:
public void cleanDokument(HttpServletRequest request,HttpServletResponse =
response) throws IOException
{=09
// Get the calling HTML Document define the Writer and open the =
connection
URLConnection connection;
URL request_url =3D new URL(request.getHeader("referer").toString());
PrintWriter out =3D response.getWriter();
connection =3D (HttpURLConnection)request_url.openConnection ();
=09
try
{
Parser parser =3D new Parser ();
parser.setConnection(connection);
=20
NodeFilter all_tables =3D new TagNameFilter("table");
NodeList list =3D parser.parse (all_tables);
Node[] nodelist;
// Seperate all table tags
for (NodeIterator e =3D parser.elements (); e.hasMoreNodes ();)
e.nextNode ().collectInto (list,all_tables);
=20
nodelist=3Dlist.toNodeArray();
=20
for (int h=3D0; h<nodelist.length;h++)=20
{
if (nodelist[h] instanceof TableTag)=20
{=09
//for schleife f=FCr die td's und tr's=09
if(((TableTag)nodelist[h]).getAttribute("id")!=3D null)=20
{
for (int i=3D0; i<nodelist.length; i++)
{
out.println(nodelist.toString());
if(nodelist[i] instanceof TableRow)
{
out.println("Row found!");
((TableRow)nodelist[i]).removeAttribute ("nowrap");
}
else if (nodelist[i] instanceof TableColumn)
{
out.println("Column found!");
((TableColumn)nodelist[i]).removeAttribute ("nowrap");
}
}
out.println(nodelist[h].toHtml());
}
}
else if(nodelist[h] instanceof TableRow || nodelist[h] instanceof =
TableColumn)
{
out.println("Else erreicht!");
out.println(((TableRow)nodelist[h]).getText());
}
}
//makePdf(out,response);
}
catch(Exception e)
{
out.println("Fehler beim Parsen!");
e.printStackTrace(out);
}
}
Does my nodelist contain the tr and td tags? Is it right to say =
instanceof TableRow????
Many thanks and best regards
Michael

Are you looking for Option tag that is selected at load time, I mean has SELECTED attribute? I don't know how well will this work because most of time OPTION tag's state is set by JS in DOM.

Hello, Could anyone advise me on the best way to go about querying a SelectTag for which of the child OptionTags is selected if indeed any are? I was looking for something like a isSelected() method within the OptionTag but didn't see anything. It's very possible i've missed something basic, if so apologies and thanks in advance. |

Here is some sample code... Sorry it is not java. But it should give you =
idea.
static void GetValuesFromTestPage()
{
FileStream obFile =3D new FileStream("TestPage.htm", FileMode.Open);
Source obSource =3D new InputStreamSource(obFile);
Page obPage =3D new Page(obSource);
Lexer obLexer =3D new Lexer(obPage);
Parser obParser =3D new Parser(obLexer);
NodeFilter obTagFilter =3D new TagNameFilter("input");
NodeFilter obAttribFilter =3D new HasAttributeFilter("name", =
"displayName");
NodeFilter andFilter =3D new AndFilter(obTagFilter, obAttribFilter);
NodeList inputs =3D obParser.ExtractAllNodesThatMatch(andFilter);
if (inputs !=3D null && inputs.Count =3D=3D 1)
{
INode obNode =3D inputs[0];
Console.WriteLine(((ITag)obNode).GetAttribute("value"));
}
obFile.Close();
HTML parser");
}

Ted, I don't think HTML Parser is what you need. It's primary use-case is programatic extraction of information from web pages, i.e. spidering, with some facilities for re-writing. As far as I know, there isn't anyone using the HTML Parser as the parsing component of the JEditorPane, and I don't believe anyone has written a browser based on it. You might want to try some of the java based browsers, e.g. shogun <http://sourceforge.net/projects/shogun>, JXWB <http://sourceforge.net/projects/jxwb>, or others <http://sourceforge.net/softwaremap/trove_list.php?form_cat=91> that purport to do what you want.

HTMLParser is not a browser so it is not going to be possible to get coordinates and positions of elements directly. You may have to write some addin on top of the parser where you load the output of the parser into some UI controls and then get the position. Just curious, is there some specific functionlaity you are looking for by knowing the coordinates?
