How to parser a HTML page to get its variable and values?

Hi, everyone, here is my situation:
I need to parser a HTML page to get the variables and their associated values between <form>...</form> tag. for example, if you have a piece of HTML as below
<form>
<input type = "hidden" name = "para1" value = "value1">
<select name = "para2">
<option>value2</option>
</form>
the actual page is much complex than this. I want retrive pare1 = value1 and para2 = value2, I tried Jtidy but it doesn't reconginze select, could you recomend some good package this purpose? better with sample code.
Thanks a lot
Kevin

See for example Request taglib from Coldtags suite:

  • How to embed a HTML Page in a Web Template and display it

    Hi All
    Can you please share ideas how I can embed a HTML page in a web template and how I can make it displayed as a popup when a button is pressed.
    Also, how do I call a HTML page stored in Portal KM from the press of a button in the web template.
    Your help is greatly appreciated.
    Thanks
    Karen

    Using C# or javascript to authenticate the user to AD to read the property directly will be very difficult. Creating a custom user profile property and adding a sync from AD to that property is definitely the easiest way to do what you are describing.
     Once its in User Profiles there are lots of samples on how to add it to the page.

  • How to parser a html page and get useful information?

    now ,I try to get the page by the url,after getting the whole page,
    is there any way to get the useful text ,and abandon other ,liks ,ad likes,
    other related links?
    I try to use java.util.regex.*;
    is there any other methods for dointg this?

    Regex isn't a good method unless your requirements are quite simple. In general if you want a Java HTML parser they are not hard to find -- "java html parser" is a good choice of keywords for an internet search.

  • How to create a html page

    Hello,i am very new to dreamweaver 8,and i have searched
    everwhere possible on how to create a html page.My website has a
    navegation bar.And on the navegation bar it has links,like
    forums,your accounts,and etc,but thats already integrated with the
    website.Now i have an option in the admin area,wher i can create a
    new category so that it would show up in the navegation bar,and i
    have a drop down menu where i cans select what to put in that
    category.But also i have an option to put a external url,so that
    when they click on it,it will take them to where that link is
    directed.The point is that i asnt to make a category in the
    navigation menu that says Lirics.So that i can put lirics of songs
    and etc,and that when users click on that link it will take them to
    the lirics page..Do you guys understand?Sorry for the bad english,i
    am now quite good with it..

    The most eloquent description will do nothing for us. To get
    a solution to
    your problem, we must see your code. Can you upload the file
    and post a
    link to it, please?

  • Parsing an html page

    i am trying to parse an html page read from the internet.
    i assume i need to create a URL of it's address, but after that im not sure how i go about reading the lines of that html page.
    i would like to load each line as a String into an array or a Vector so that i can easily parse each line from there...
    any tips?
    thanks.

    haha...this is what i ended up doing...and i was able to parse it all pretty easy...
    BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
    in.readLine();
    thanks!

  • How to upload an html page?

    Hi, I have an urgent problem and no one here in office seems to be able to help me.
    We have an html page uploaded in our portal and now I need to upload a new version of it. I have no idea on how to use oracle portal interface to do the job.
    If it helps, the page now is here: http://www.companywebsite.net/pls/portal30/docs/FOLDER/FOLDER1/FOLDER2/FOLDER3/FOLDER4/htmlpagename.HTM
    Thanks for any suggestion

    If the HTML page was uploaded as a "file" item type, then in order to edit the file, you must edit the file using whatever client side tool you want. Save the file locally.
    Then in Portal, when editing the page the HTML file has been uploaded to, click the edit pencil for the HTML file and re-upload the new version of the HTML file.
    Things uploaded to Portal as file types, you cannot directly edit the file within portal - only upload new file versions.
    Not sure if this was your issue or not ... but thought maybe it was.
    thanks,

  • I am trying to delete pages I have crated in numbers, but can only see them in print preview. Without print preview I do not see them. How can I delete these pages, but keep others before and after?

    I am trying to delete pages I have crated in numbers, but can only see them in print preview. Without print preview I do not see them. How can I delete these pages, but keep others before and after?

    Hi Crushed,
    Numbers doesn't have pages. It has a canvas that holds objects such as tables and charts.
    Drag the objects from the bottom of the canvas onto the white space above. That will reduce the number of "pages" (sheets of paper) that will print.
    Regards,
    Ian.

  • How do I use Migration Assistant to get my Mail and Keychain settings from

    How do I use Migration Assistant to get my Mail and Keychain settings from my Power Mac G5 2.3Ghz? I just purchased a new 2.5 MacBook Pro which will be delivered tomorrow, and I want to to know how to transfer Mail and Keychain?
    Thank You in advance for your reading and replying.
    Kindest Regards,
    Sebastian

    Rather than using Migration Assistant, which can cause trouble with the PPC to Intel change, simply boot the G5 in FireWire target disk mode and manually transfer the following:
    /Home/Library/Keychains (copy the whole folder)
    /Home/Library/Mail (copy the whole folder)
    /Home/Library/Preferences/com.apple.mail.plist
    You might want to look over Kappy's helpful guide for migrating, which covers the full process for a manual migration (including the above files).
    Hope this helps...

    How do I select multiple files under "Get File Info"and lock or unlock them all? It seems to do it automatically when I have 10 or more selected. But how do I lock or unlock 5 or 6 files in one swoop? Thanks

    Select the desired files then press OPTION and select Show Inspector from the Finder's File menu.

  • How do i recover music from old computer. its broken and i did not have the music backed up on any other hard drive.

    how do i recover music from old computer. its broken and i did not have the music backed up on any other hard drive.

    OK, well, seems like you need to lose the attitude if you really want help.
    There are several ways to get music from iTunes on your computer to your device.
    The easiest is to sync directly with iTunes by connecting your device to your computer, selecting the device, setting up your Profile pages, and then clicking the Sync button to sync.
    First you want to open iTunes and under Preferences>Devices, make sure that you are not syncing automatically:
    Make sure that box is checked.
    Then follow the instructions in the article below for either your computer or your Mac to set up your Profile pages and to sync your music via iTunes:
    WINDOWS IOS SYNC ITUNES 11
    iTunes 11 for Mac: Set up syncing for iPod, iPhone, or iPad
    You can also directly download music from iTunes to your device by going to the iTunes icon, going to "Purchased", and selecting the items that are not on your device that show a little cloud next to them. Click on the cloud and the music will download.
    You might also want to familiarize yourself with your iPhone 5 manual. It has all the answers you cannot find on Google or by trying to just do it by brute force. If you would take a little time to read about your device and how to use it, you might not be so frustruated and unnecessarily snarky to people who are trying to help:
