From HTML string to HtmlDocument?
I have a String consists of a HTML string e.g. <br>Hello</br>
How to convert it into a javax.swing.text.html.HtmlDocument?
You can't convert any String directly to HTMLDocument !
HTMLDocument is a back-end of any HTML editor (eg.,JTextPane / JEditorPane).
If you want to have an HTMLDocument that represent your string "<br>Hello</br>" ,then do one thing. (Your HTML string is still invalid ,cos there is no such TAG called </br>)
JTextPane text=new JTextPane();
text.setContentType("text/html");
text.setText(yourHTMLString);
HTMLDocument doc= (HTMLDocument)text.getDocument();

How to REMOVE [b] H1 Tag[/b] from HTML without changing other Tags?
Hi there!
I'm searching for a method to remove Tags from HTML (using HTMLEditorKit, HTMLDocument ...).
My current code is as follows:
// first get the whole paragraph
int iCaretPos = tpMyTextPane.getCaretPosition();
Object oAttrib;
HTMLDocument.BlockElement oElem = (HTMLDocument.BlockElement)oMyDocument.getParagraphElement(iCaretPos);
AttributeSet oAttribs;
SimpleAttributeSet oNewAttribs;
int iParaStart = oElem.getStartOffset();
int iParaEnd = oElem.getEndOffset();
tpMyTextPane.select(iParaStart, iParaEnd);
// the following only fetches the Tags that are valid for the whole paragraph!!!!!
oAttribs = tpMyTextPane.getCharacterAttributes();
oNewAttribs = new SimpleAttributeSet(oAttribs);
if(iParaEnd - iParaStart > 0)
// now analyse the attributes (remove all paragraph-tags)
for(int iIndex = 0; iIndex < oaOurFormatTags.length; iIndex++)
oNewAttribs.removeAttribute(oaOurFormatTags[iIndex]);
if(iParaEnd - iParaStart > 0)
oMyDocument.setCharacterAttributes(iParaStart, iParaEnd - iParaStart, oNewAttribs, true);
tpMyTextPane.setCaretPosition(iCaretPos);
tpMyTextPane.requestFocus();
tpMyTextPane.repaint();
}This code works for me, but all Tags of the selected paragraph are removed. That means:
<P><H1>This is a <B>test</B> text<H2></P>
will be converted to:
<P>This is a test text</P>
but I want it to be converted to:
<P>This is a <B>test</B> text</P>
Is there any other method to remove specific Tags (<H1>, ... <H6>) without touching other tags????In February I wrote a feature request about this. Today it has been accepted to the bug database. Please make your vote:

How to extract an element value from a String of HTML
I have a web service that returns a fragment of HTML that contains a number in a table. The return parameter type is a string. I need to get this number and use it in a BPEL while loop, as the condition for the loop (while the number > 0).
I have tried using the function bpws:getVariableData() but the BPEL PM faults and says: XPath expression failed to execute. Error while processing xpath expression. I think this is because I am trying to apply an XPath expression over a String variable.
The return value from my web service looks like this:
<whileConditionResultSet>
<part xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance" name="response">
<ns1:string_Response xmlns:ns1="http://systinet.com/xsd/SchemaTypes/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="d:string">
<p>SQL Query: select count(*) from delta_manages</p>
<p><table border='1'>
<tr> <th bgcolor='#C0C0C0'>COUNT(*)</th></tr>
<tr> <td>28</td></tr>
</table>
</p></ns1:string_Response>
</part>
</whileConditionResultSet>
How do I get the value from the HTML table into a BPEL variable?the doSqlService() which executes an arbitrary SQL statement, returns a string of HTML like this:
<doSqlServiceResponse>
<part xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance" name="response">
<ns1:string_Response xmlns:ns1="http://systinet.com/xsd/SchemaTypes/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="d:string"><p>SQL Query: select count(*) from delta_manages</p> <p><table border='1'> <tr> <th bgcolor='#C0C0C0'>COUNT(*)</th></tr> <tr> <td>14</td></tr> </table></p></ns1:string_Response>
</part>
I then copy the result to the whileResultString variable
<variable name="whileResultString" type="xsd:string"/>
<copy>
<from variable="doSqlServiceResponse" part="response" query="/ns1:string_Response">
</from>
<to variable="whileResultString"/>
</copy>
I realise too, a root element will be needed. This is not a mission critical problem as we could change the web service at the other end. It was originally designed for a client to display the results rather than use them within a business process. Anyway, I'm just interested to know if I can create a node from this string data in BPEL.

Remove HTML tags from a string
I have a string that contains a couple of HTML or XHTML tag, for example
lv_my_string = '<p style="something">Hello <strong>World</strong>!</p>'.
For a special use case, I want to remove all HTML from that string and process only the plain text
lv_my_new_string = 'Hello World!'.
Is there any method, function module, XSLT or anything else for that already?Hi Daniel,
I tried using the FM (SWA_STRING_REMOVE_SUBSTRING) but I guess it is expecting a particular pattern which is not so apparent in your case. Iu2019ve written a small piece of code which you can try using in a FM or a PERFORM and that should do the trick. Please let me know if you have any questions.

How to remove HTML tags from a String ?
Hello,
How can I remove all HTML Tags from a String ?
Would you please to give me a simple example ?
Best regards,
EricHere's some code I cooked up. I have created an object that processes code so that it can be incorporated directly into a project. There is some redundancy so that the it can be used in more than one way. Depending on your situation you might have to make the condition statement a little more sophisticated to catch stray ">" tags.
I have also included a Tester application.
//This removes Html tags from a String either by submitting the String during construction and then
// calling getProcessedString() or
// by simply calling " stringwithoutTags=removeHtmlTags(stringWithTagsSubmission); "
//Note: This code assumes that all"<" tags are accompanied by a ">" tag in the proper order.

Out of Memory error while builng HTML String from a Large HashMap.
Hi,
I am building an HTML string from a large map oject that consits of about 32000 objects using the Transformer class in java. As this HTML string needs to be displayed in the JSP page, the reponse time was too high and also some times it is throwing out of memory error.
Please let me know how i can implement the concept of building the library tree(folder structure) HTML string for the first set of say 1000 entries and then display in the web page and then detect an onScroll event and handle it in java Script functions and come back and build the tree for the next set of entries in the map and append this string to the previous one and accordingly display it.
please let me know whether
1. the suggested solution was the advisable one.
2. how to build tree(HTML String) for a set of entries in the map while iterating over the map.
3. How to detect a onScroll event and handle it.
Note : Handling the events in the JavaScript functions and displaying the tree is now being done using AJAX.
Thanks for help in Advance,

Stripping HTML Tags from a String
What's the best way to remove html tags from a string (i.e. user input)?
Can you give an example? You can do substring, if your passing spaces between pages you can do a trim to the variable. Also look at the indexOf(). Look at methods relating to java.lang.String.

Parsing the FRAME tag from HTML pages

How to change inner content of HTML tag using HTMLDocument?
I want to change the inner content of an HTML tag from a HTMLDocument. The tag is like
<span id ="id1">Replace me</span>.
So I want to change the text "Replace me" inside the span tag and replace it with an other text.
I can get the span element using
HTMLDocument.getElement("id1")
I have tried many things with the Element instance i got from getElement. But I find no way to change the inner content of the HTML element. Any ideas?If I use JDK 1.5 the SPAN tag works, so I checked the core of the problem which is inserting HTML code in an HTML tag.
setInnerHTML works fine for block tags like DIV but not if the tag is a leaf element like the SPAN tag. I have tried to use the following code for leaf elements:
Element elem = m_htmlDocument.getElement(id);
int nStartOffest = elem.getStartOffset();
int nEndOffset = elem.getEndOffset();
int nLength = nEndOffset - nStartOffest;
m_htmlDocument.replace(nStartOffest, nLength, html, elem.getAttributes());
This works, but only if the new HTML string does not contain HTML tags like a link <href..... >. If the string contains HTML tags the replace method masks all characters like < or >. So the link is not shown as link in the HTML page but as HTML text.
The next thing I have tried is using
m_htmlDocument.setOuterHTML(elem, html);
This works too but it replaces the whole original HTML element like the SPAN tag.
So there is still the question how to insert HTML text into a leaf Element in a HTMLDocument. -

Problem to display Animated Gif from HTML into JEditorPane
I have a problem displaying animated gif that comes from URL (HTML) into JEditorPane.
Let me show you the source I have:
* @author Dobromir Gospodinov
* @version 1.0
* Date: Dec 6, 2002
* Time: 6:47:53 PM
package test.advertserver;

e.printStackTrace();
JPanel panel = new JPanel();
panel.setPreferredSize(new Dimension(500, 500));
panel.add(ed);
frame.getContentPane().add(panel);
frame.pack();
frame.setVisible(true);
}Part of the returned from servlet HTML includes an img tag:
<img src="/images/MyAnimatedGif.gif" alt="animated gif comment" width="480" height="50" border="0">Let us assume that MyAnimatedGif.gif has 10 frames and gif is looped - when the 10th is dipslayed it has to display the 1st and so on.
JEditorPane displays frames from 1 to 10 correctly but does not start from the first again. Instead JEditorPane displays a broken image.
I locate where the problem arise:
JEditorPane has an HTMLEditorKit that creates javax.swing.text.html.ImageView instance for every IMG tag.
And here is the problem:
ImageView has an ImageObserver necessary for the asynchronous image download. ImageObserver has the imageUpdate method. But this imageUpdate method is never called with ALLBITS flag raised up. Instead, after the last frame of MyAnimatedGif.gif is downloaded the imageUpdate method is called with flag ERROR raised up. Obviously this is a bug of Sun's implementation. Finaly the flag ALLBITS has to be received for normal end of image observing. But ALLBITS flag does not come.
So, can anybody help me how to load an animated gif within JEditorPane completely.
Thank You in advance,
Dobromir Gospodinov
P.S. If somebody of you wants to debbug what happens within ImageView will have to implement it (and related classes too, because of the limited package visability) borrowing the source from Sun's ImageView.I'm also having this problem with java 1.4.1 I discovered that some animated gifs work fine, while others stop animating.

Escape single quote from a String variable
Hi,
I have a String variable called "name" which i am using in my form tag.
<form name=test action="test.jsp?fname=<%=name%>" method="post">
But i am getting Javascript error if the "name" variable contains a string with some special characters like single quote( ' ).
Plz help me to escape this special char from my String variable.
Thanks..You need to url-encode the value using the URLEncoder class.
http://java.sun.com/javase/6/docs/api/java/net/URLEncoder.html
For example:
<form name=test action="test.jsp?fname=<%=URLEncoder.encode(name, "ISO-8859-1")%>" method="post"> -

but the following files don't work .
<%@ page language="java" import="java.net.*,java.io.*"%>
<%@ page import ="java.util.*"%>
<%
try
String SContent = request.getParameter("click");
String SDocName = "temp.doc"; // out put file File Name
ServletOutputStream stream= response.getOutputStream(); // Getting ServletOutputStream
response.setContentType("application/msword"); // Setting content type
response.setHeader("Content-disposition","attachment;filename=\"" +SDocName+"\""); // To pop dialog box
BufferedInputStream in = new BufferedInputStream(new FileInputStream(SContent));
int c;
while ((c = in.read()) != -1){
stream.write(c);
in.close();
stream.flush();
catch(final IOException e)
System.out.println ( "IOException." );
catch(Exception e1)
System.out.println ( "Exception." );
%>I am so confuse, what is the path and file name I sould give ? for example my click should equal to http://******/Test/display.jsp?click=00-1Hi all,

Thank you! -
How to parse select lines in an html string?
I've been writing a program to deal with demographic data and the first server it calls returns an xml string. However, the backup server returns an html string instead of an xml string, so the formatting is a bit different. I was going to use a regex as I did with the xml server, but regex's don't work that well with html. i was wondering if you could offer some advice on how to effectively parse the html string? It is in this format <html>

}Currently it functions using a regex, and executes, but doesn't return any numbers, only returns zeros...If you could help me out with this, that would be amazing! Thanks so much.hmm, is there a way to do it without an external API? Of course there is.
looks like i have to download the API and the idea behind the program is to make it so multiple people running only java can run the program, without having to download APIs, ect, to make it run. Not sure if that is what JTidy entails, but is that what you were suggesting?Personally, I don't understand the resistance to using well-tested tools already in existence as opposed to trying to rewrite a shallow facsimile of said tools. You can distribute the JTidy library along with your application and save yourself a great deal of development and debugging effort.
