How to detect and get the valid html tags?
View 2 RepliesI am planning to create a system for my case study wherein i can Add tags from images and search for it by "tags" such as photobucket. For example i open an image to my system, and it's file name was "WhiteHouse.jpg" and i added or tagged it as "Building". Once i search on my computer, and type the word/keyword "Building", the image "WhiteHouse.jpg" will be displayed on search results as i tagged it on my system.Is that possible guys? or i can only search by tags using my system/application? and not in the search command in my computer?If it is possible please tell me what to do. or if you have sample vb.net2008(windows Application) files it will be helpful. Or if you have sites related into it. pls send me those links, especially downloadable vb.net files w/ codes for further studying.

View 6 RepliesWith my code as I have a trouble with the returned strings that I have extracted from my php source to add the strings in my listview.
I'm reading the tags of mystrings1 and mystrings2 for each paragraph from the php source. I got the returned strings which it looks like this:
PHP
<p id='mystrings1'>my strings</p> | <a href="http://xfvasfasfasfasf">Link</a> </td> | <a href="delete.php?id=0">Delete</a> </td> | <span id="mystrings2">Enabled</td>
I want the returned strings to be like this when I reads the tags of mystrings1 and mystrings2 while ignore the other tags.
PHP
<p id='mystrings1'>my strings</p> | <span id="mystrings2">Enabled</td>
Here's the
Public Sub timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs)

timer1.Stop()

Do you know how I can ignore the other tags when I get the returned strings of mystrings1 and mystrings2?
This may sound really stupid but I have to ask cause I'm not finding this answer anywhere.I have an application where the user will need to sign up for a new user account on the website [URL]..However when I am using Firefox's plug-in Firebug to view html I am getting something totally different than when I just right click on the site and view the page source.
What I am trying to do is to get the captcha from the website and display it in a picturebox on the application so the user can view the captcha, solve the captcha and then the app post is back to the service for a response.
Here is the source that I am getting using Firefox's Firebug to inspect the element:
<td>
<input type="hidden" value="Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK" name="iden">
<img class="capimage" src="/captcha/Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK.png" alt="i wonder if these things even work">
</td>
[Code]...
Why would the two be showing me two different versions of the HTML?
And how would you be able to grab that source to view in a picturebox using webclient?

I'm looking for an efficient means of extracting an html "fragment" from an html document. My first implementation of this used the Html Agility Pack. This appeared to be a reasonable way to attack this problem, until I started running the extraction on large html documents - performance was very poor for something so trivial (I'm guessing due to the amount of time it was taking to parse the entire document).[code]...
View 3 RepliesI am trying save a value from an input tag in some HTML source code. The tag looks like so:

I have the page source in a variable (pageSourceCode), and need to work out some regex to get the value (3 in this example). I have this so far: [Code] Which works fine most of the time, however this code is used to process source code from multiple sites (that use the same platform), and sometimes there are other attributes included in the input tag, or they are in a different order, eg:
<input class="someclass" type="hidden" value="3" name="user_status" />
I just dont understand regex enough to cope with these situations.
