2008 : Extracting Parsing Keyword Tags, Title Tags, Td Class, Meta Tags Etc?
Nov 8, 2009
I'm trying to analyze web pages for seo. I'm trying to create my own personal tool to extract all the keywords and tags from web pages (a little clearer).I already know how to extract or parse links and text from web pages. The issue is that I tried to implement title tags, body tags or keyword tags in general via using the following code:
Dim theElementCollection As HtmlElementCollection = WebBrowser1.Document.GetElementsByTagName("a")
For Each curElement As HtmlElement In theElementCollection
If curElement.GetAttribute("href").Contains("http://twitter.com/") Then
[code]....
Try to extract all the keywords from the title, body etc. for this page:[URL] and send it to separate textboxes (title keywords in textbox1, meta tags in textbox2 etc.).

I was just wondering how to extract or parse any particual tags (whichever I specify) from webpages. I know how to extract text and links from webpages, but I tried to use the same method from the following code for div tags, title tags etcetera and it doesn't seem to work:
I have a website with product pages that are created dynamically depending on the itemws in my database. The site works fine with no errors. I now would like to add Meta Tags to the header.
When the pages are created I would like to dynamically/programmically set the meta tags for that page - Keywords, etc.
How can I add them using VB.Net in Visual Studio 2008. I am using a masterpage for the overall layout if that affects anything.
I 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.
How do I Edit and Save Image EXIF / Metadata / FileInfo without using an external DLL?
Project:I'm building an app for personal use to rename, retag, and organize the apocalyptic quantity of images I host on my personal website. As I have been collecting funny pictures and such for several years, there is no real rhyme or reason to the file naming conventions. Ergo, Image0001.jpg needs to be renamed to a descriptive filename, and the Metadata fields need to be filled in.
The desired process will take an existing jpg, gif, png, tiff or bmp and do the following:
load image into memory convert bmp files to jpgs if needed (for a smaller file size, mostly) load image tags into ImageData Structure (see below)

[3] load image tags into ImageData Structure (see below)
[4] load file data into ImageData Structure (where needed)
[5] display image and tags for user to edit (In a Picture Box and several Text Boxes)
[6] allow editing of fields and renaming of the file
[2] Type in Description: "lolcat ceiling cat sends son".
[3] ImageData.FileName changed to "lolcat-ceiling-cat-sends-son.jpg".
[4] ImageData.Name, .Keywords, .Title, .Subject, and .Comments changed to "lolcat ceiling cat sends son".
[5] Save file with new filename and save all new tag fields.
(Later, I will also be using SQL to build a referential database with links to the online copies of these files to allow for searching by keywords, subject, filename, etc, but that's another layer that's much easier than this one. At least to me.)
Problem:So far, several days of research have yielded almost no measurable progress. Information has apparently been inexplicably hidden behind a bunch of unexpected search keywords. Current Code as is:
I'd like to look into extracting EXIF tags/data from jpg images. I've looked around but can't seem to see any simple example. Anyone able to point me into the direction of pulling out the model/date values etc out of EXIF data?
<td style="text-align: center;"><img src="http://www.pkmdb.com/res/icons/001.png" alt="Pokemon" /></td> <td style="text-align: center;">001</td> <td style="text-align: center;"><a href="http://www.pkmdb.com/DL/PKM/bulbasaur.pkm">Bulbasaur</a></td> <td style="text-align: center;"><img src="http://www.pkmdb.com/res/types/grass.png" alt="Type" /></td>Different Number, different name. I need a way to get the number and name out of these tags. I'm rather terrible at this, and I've seen examples on the site, I just don't know where to start really on this.
How do I edit JPG File Title, Subject, Comments, and Tags/Keyowrds?The Exif information provided was helpful, but in the end did not actually solve the real riddle I was working on. So I'll take another angle at describing the desired result:
I want my VB.NET app to allow me to edit the following details of a Jfile (see image):
Title, Subject, Comments, and Tags/Keyowrds
I had a handy image to include but not enough points to post it. Weak.
RIGHT CLICK A .JPG IN WINDOWS and select PROPERTIES
Win XP: Select the "Summary Tab" and Look at the "Description" group
Win7/Server 2008R2: "Details Tab" and look at "Description" group
how to edit those fields through VB.net in Visual Studio?
EDIT: The ultimate goal is to use the image viewer/editer that I built, to sort thousands of images of random webjunk I have collected over the years.Upon viewing the image (say "00001.jpg") and figureing out what it is ("ceiling cat sends son" picture of a lol cat), I want to type in the description (already done in the form). When I hit enter I want to rename the file (from "00001.jpg" to "ceiling-cat-sends-son.jpg", then fill in the keywords, title, subject, and comments fields with the same data: "ceiling cat sends son".
local indexing and with my (later) automating a SQL server referential database for use with site wide searches on my website. The ONLY thing I can't seem to figure out is how to modify those four fields as if I had right-clicked the file and added the keywords.
I didn't like the fact that I had to use the MSHTML stuff (cause I think IE uses it also, and we all know that IE sucks :) ) and that I had to add code the make it work.Don't want to start a browser-war thread so neglect my last remark.Is there a different (/better) approach of parsing html-pages in VB.Net.Basically what I'm trying to do is get all the links (<a> tags) and embeds (<object> tag) on a page.
I am trying to figure out how to get the "1:39" from this page's source:
[Code]....
I have searched the forums through pretty well, and cannot find a solution. I am assuming I would have to use Regex to get the numbers specified. If I need to provide more of the page source,
I am trying to format xml entries I have so that I can use the xmltextreader without getting errors. I added a default header and footer in the event I notice there is no opening or closing tags. I remove illegal characters and check for unicode but I always find an issue where an entry slips in and gives the error: data at the root level is invalid and when I check that entry is slipped through the cleaning process or just has an unmatched tag somewhere.
Now I use Dim stringSplitter() As String = {"</entry>"} ' split the file content based on the closing entry tag sampleResults = _html.Split(stringSplitter, StringSplitOptions.RemoveEmptyEntries) To split my xml into individual entries before I start the cleanup process.
Here are my default headers: Private defaultheader = "xmlns=""[URL]""" Private headerl As String = "<?xml version=""1.0"" encoding=""utf-8""?>" & vbNewLine & "<entry " & defaultNameSpace & ">" Private footer As String = "</entry>"
Is there any tool in the .net framework that can detect and cleanup unmatched tags so that I can get this to work.
i have text in textbox1.text How can i wrap html tags around that text by clicking a button. Example : Textbox1.text has "Hello there" in it When i click a button i want it to display :
I've crafted together a quick web page together to look something like this: <span class="vanity">Just A Test Document</span> <br> <B>Hey VBForums!</B> I have a standard text box, a button & web browser control on my form. On the load event I send my browser out to this web page. I had a quick question, after clicking button 1, does someone know how I could get the data from in between these 2 tags '<span class="vanity">' & '</span>' into Text Box 1?
This is the format of the html, i just need to gett he users age and name, using reg ex i have so far:
Dim proxySourceHTML As New Regex("(?<=<tr bgcolor=""#ffffff"" class=""text"" height=10>"").*?(?="".*?"">)", RegexOptions.IgnoreCase Or RegexOptions.Singleline) Dim matchesFound As MatchCollection = SourceHTML.Matches(GETHTMLResponse)
Did anyone already try to read RFID tags but not by reading request?I mean, When some tag is readable can't just the RFID reader detect it?So far this is the code I've been trying to use without success.

When in VS 2008 if a developer hits the ''' it generates the XML comment tags for you, but this only works when the project setting for "Generate XML documentation file" is checked. Is there a way to tell VS to generate the XML Comment tags, regardless of the project setting? I think it is possible that someone may want comments but not create a XML documentation file. In this case I am exceeding the current Team Settings, yet other developers don't want me to change this project setting. This forces me to flip this back before checking in the project. I have the same problem with other Project settings like "code Analysis". This is only a problem for VB.NET projects.
what i am trying to do is extract information beween two tags in some html from the source of a website. The contents of the text between the two tags will always be different. the code i currently have is;
I know how to extract the ID3 tags from mp3 but how do I do it for .mpg.I need info like Genre, Artist, Song Title etc.Searched Google but couln't find any good link. The only link that I came across was this[URL]..This is in vb6 and it doesn't give the info that I wanted.
