well in html parser we require to give some url in which it parse out the tags as per the requirementReally? Which parser did you choose which had that limitation?
but what i want is i want to give my simple string as an input and in that it parse out the html tagsThe standard XML parser built into Java allows that. Convert your HTML to XHTML and use that, if you can't figure out how to get your chosen HTML parser to parse from a string. Or better, go back to the documentation for the HTML parser you chose and look again.

  • I need my java program to read HTML tags from the browser...

    so, i've made this java GUI, which can run from my internet explorer toolbar...
    as of now, this program doesn't do anything, it just produces an interface with blank fields
    i want these fields to automatically add information about the current web page on the browser... basically, is there any way that my java program can automatically read the HTML source of the web page opened? i just need it to be able to capture the page's URL and title.
    i programmed it using NetBeans, and it runs from the .jre file outside of NetBeans. I got an icon for it to appear on my IE toolbar by editing my computer's registry. When I click on this icon, my GUI runs, but doesn't do anything. Can I get it to read (i.e. automatically output on one of the textfields on my GUI) the URL and title of the webpage that i'm currently on? I want this to work like Bookmarks/Favourites does, so that means i don't want to download every single webpage before reading from it.
    any help will be greatly appreciated.

    I think that if you wanted to do this, it would involve something like the following:
    Have your toolbar GUI listen on a local port
    Set IE to proxy to localhost at that port
    Tunnel/proxy all requests. This will allow you to intercept the page source and the original request. Between the request URL, the request payload, the HTTP headers of request and response and the response payload, that's everything the browser would 'see'. The downside of the above is that you cannot intercept SSL (HTTPS) requests. You might be able to use the Windows/IE API (native) to fetch page source, but this would definitely be an application and O/S specific solution.

  • How to extract HTML page from the internet

    i am new to java, i wish to know how to extract Html page from the internet and also how to identify the differences between the images and text information?

    You can create a java.net.URL that points to the file you want to "extract" and read the HTML code (or what ever that file contains) from there using the inputstream given by URL.openStream().
    The difference between images and text... well, images are embedded in html using the img-tag. example: <IMG src="http://forum.java.sun.com/images/reply.gif" alt="Reply">. Attributes width, height, alt are sometimes left out and there may or may not be quotes around the values and everything is case insensitive... you'll be having hard time trying to parse the input so I'd suggest using existing parsers.
    What are you trying to do anyway? You can load a URL directly to a JTextEditorPane with the setPage(URL page) method...

  • Handle invalid html tag in the htmlText

    Hello,
    I"ve a <mx:text control which takes html text, it is a chat application, so, the client will simply concatinate the text comming through the network. But if the html text has invalid tags, it does not show the rest of the chat messages.
    I get something like
    <a href="http://google.com&quot;">http://google.com<a>
    here the red text is creating problems.
    P:S: you might want to say, handle it when sending from other client, but, we are dealing with legacy data, which has a lot of html format issues.

    Thanks for responding
    I understand that adding more HTML tags will change the font size. What I don't get is why it changed from one size to another by adding a HTML tag in the first place. I figured that it should have retained the same size it was without the tag when I added the tag. If I had added a font tag I would have excpected the font to change size but I added  a href.
    Sorry for the confusion.

  • E-Mail Notification shows up HTML tag in the body

    Hi all,
    We successfully implemented the email notification. we have the standalone version of 2.6. We are now seeing the notification mails delivered to our mail boxes.
    We need some assistance, in setting the type of notification. We have set the Global preference for all the users as "Plain text mail with HTML attachments" and we have set the preference at user also like "MAILATTH". But the body of the notification mail has HTML tags along with the contents, we do have the attachment, when we open it , it works fine.
    our problem is , how to see the mails without those HTML tags, in the inbox.
    Any advice,
    Johnson

    There was a newline character in Subject field.
    Removing that fixed the issue.

  • How do I set BI Publisher to read html tags from the database?

    How do I set BI Publisher (Release 10.1.3.4) to read html tags from the database? For example if the text is quoted with a bold tag I want my output to display the text in bold. Is there a setting or something I can set?

    I took a look at Tim Dexter's blog as suggested and the sample worked, but for the elements in the xml file not for the value coming from the database, however this is good to know as well!
    I have data in the data base column which looks like this:
    'MS Applied <B(bold tag)> Mathematics</B(bold tag)>University of Southern California'
    I want the data to be rendered like this:
    'MS Applied <B>Mathematics</B> University of Southern California'.
    In Report Builder on the property sheet I would set Contains HTML Tags property to Yes and the report would render correctly.
    In BI Publisher 10.1.3.4 I can not seem set it to read this I have change the configure properties of the report to Character set to HTML and Make HTML output accessible to True. I just can't figure out what I'm missing.
    Thank you for any assistance you can offer.

  • Getting the regular expression from the given text

    Hi
    I need to develope an application which can convert the given text into the regular expression. I need that when i enter any text in textarea that should be translated into regular expression in another panel. but i could not find the method or technique which can do so. plz help me to resolve this issue.
    Thanks Imran khan.

    well, there are an infinite number of regular expressions for an arbitrary piece of text, so you will have to qualify in your mind what the purpose of the regular expression is.
    For instance, it is trivial to create a regex for a string just by copying the input text, and inserting \ before any special characters. But this pattern would probably be quite silly.

    And that is a critical distinction to make. HTML parsing is horribly complex. XML is quite easy. For HTML you have to code your own parser in PL/SQL. XML can be parsed using the XMLTYPE class/data type in PL/SQL.
    So if you need to find a single specific tag in HTML - I would not try to treat it as XML. I may not even try to use regular expressions.
    I would do a basic substring search for the start of the tag. Read the data following the tag. Ensure that there are no nested or embedded tags in the data. Until the end tag is read. Because HTML is that much abused - and because that is an accepted norm as parsers used by browsers deals with that abuse without complaining.
    Proper HTML is mostly a myth in my experience of "screen scraping" web servers for data extraction as they do not have web services supplying the data.

  • Problem removing html tags from the text retrived

    Hi there,
    I am using jdbc to connect the database and retriving the data. In one of the columns along with the description there are some html tags in few of the recors of that column. is there a way to retrive the text only ignoring the html tags in between. Or can i retrive and then strip off the html code in the text to display only normal text.
    example of the data retrived which are pipe seperated and one of the columns has html tags in it:
    209|The euphoria |187945-2|http://www.abc/lst.jsp?mktgChannel=I86023&sku=18791-2&siteID=qpF0HYnRugA|http://www.abc.com/assets/images/product/medium/18793-2_198.jpg|Rooftop Singers: Walk Right In | abc Music proudly presents THE FOLK YEARS, an unforgettable era in music history!<BR><BR><B>Featuring:</B><BR>
    <LI>The most complete collection of folk and folk-rock songs ever put together -- 132 classics!
    <LI>Original hits by the original artists!
    Now i need to remove the tags before displaying this on the output. Is there a simple way to do this.
    Thanks...

    Did you read the documentation of the trim() method,
    where it describes which whitespace it removes?I believe his problem is that
    "Some text here  
    <blah> 
    More text"becomes
    "Some text here  
    More text"... and he wants ...
    "Some text here
    More text"So, your problem is that your regex isn't matching whitespace as well.
    See the "Trimming Whitespace" section:

  • HTML Tags in the Webdynpro ABAP

    Hi Experts,
                    How to create a html page in the webdynpro ABAP, we have existing page in the HTML format. I have tried the Formatted Text View it is not supporting all existing HTML tags like <table>
    .Can u suggest me how to integrate the HTML in the Application ...

    As you stated, the SAP recommendation is to not use iFrames.  That UI element is depricated.  The recommended solution is to use the NetWeaver Portal or NetWeaver Business Client.  You create two iViews and place them both in the same page if you need to mix Web Dynpro with more free form HTML coding.  The one iView can be Web Dynpro and the other can be one of many types of technologies (static HTML, BSP, JSP, JSF, ASP.NET, etc).  You can use portal eventing to communicate between these two separete iViews if needed.

  • How to remove html tags from the pdf file ?

    Hello,
    Using BI publisher we are generating a pdf file. In the table, we have data which contains html tags. for example " test1<br> 2.test2<br> 3.test3<br> ".
    In the pdf file we need to get the output like this
    test1
    test2
    test3
    But the output is as follows :"test1<br> 2.test<br> 3.test3<br> "
    Any idea, how these html tags can be removed from the pdf file and obtain the required result?
    Thanks in advance!!
    Archana

    Archana,
    Can you wrap your code in <code> tags (use square brackets rather than angled ones), as the forum software is interpretting the HTML tags, in other words we can't see what you mean ;)
    In any case, there are a few different options (guessing at what your problem is, without seeing the actual data), you could use htf.escape_sc or replace, regexp_replace etc to substitute the values before you output them to your PDF.
    Hope this helps,
    John.

  • Conditional text - multiple tags on the same text

    I have three conditional tags in my project: e.g. A, B & C.. Some text has two tags. I defined the A layout as all excluding B &C. However, that also excludes the text that have both A & B tags.  How do I show the A text that is also tagged B?

    Hi there
    Keep in mind that if you go that route, you need to ensure ALL content is tagged. Anything untagged is always included.
    Cheers... Rick
