Is it possible to preserve whitespace inside tags? I am accessing XML nodes (containing XHTML content) in an XPathDocument using a XPathNodeIterator.Some of the tags in the nodes are not "strict" XHTML (and this is allowed in the final output of the tool). Some nodes contain image tags without the trailing space.
<img src="filename.png" alt="description"/>
When i store the resulting nodes they get nicely formatted with the trailing space.
<img src="filename.png" alt="description" />
[Code]...
As a temporary work-around i added a few regular expressions (comparing new and previous versions of the nodes) to search for and fix the "differences" introduced by parsing the XML with .NET
Is there any way in VB.NET to remove all of the whitespaces between tags in HTML? Say, I've got this:
<tr> <td>
The string I've built is an entire HTML document, and it counts everything before those tags as legitimate space, so I need to trim it out. Is there a reg ex or function out there I could use to do this?
I would like to pass a whitespace character by using the System.Text.Encoding.ASCII.GetBytes(" "), and System.Text.Encoding.Unicode.GetBytes(" ") , where " " is the whitespace Character required. What do I need to type (" ") to get a whitespace character passed.?
Im trying to find a tag inside of a tag, so far ive gotten this, but i have no idea how to find another tag inside.There are multiple li tags with data inside so once it find the li tag that equals "a username" i want to click the button tag under it.
If (WebBrowser1.Document IsNot Nothing) Then Dim Elems As HtmlElementCollection Dim WebOC As WebBrowser = WebBrowser1
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'm trying to learn the query structure. I have the following XML:
<?xml version="1.0" encoding="utf-8"?> <list> <item> <due>07 May 2012</due>
[code]....
And I'm trying to delete <item> elements with a query:
Dim DeleteItems = From e In Root.Elements("list") Where e.Element("name").Value = Text
However it isn't working. I think it's trying to select tags called <item> in the file's root, however it needs to be selecting <item> tags in the <list> element - which I don't know how to do.
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 an xml document on the internet right. Lets say it contains: <tag>goose</tag> What I want to do, is when the user clicks a button in my vb form it looks for the "tag" tag and finds the text inside the tags which is goose. Then it sets a label to equal goose, or whats in those tags.
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.
I'm creating a Website and I noticed that when the page reloads due to a postback, My variables all are unloaded so I have a Null variable,
For Example I'd Declare a String With an initial value of "" then later in the code set it to "Some Value", when a button is clicked to cause a postback, this value then becomes "" again
Is there some way to preserve variable so their values remain the same after a postback
I'm dynamically loading User Controls into a div, which I need to preserve on postback in order to call a Save method once the user is done editing them. The div and all the User Controls have the EnableViewState = True.
So... the controls load fine, but I can't find a way to preserver them on postback, I can't reload them because the user has already input data into the usercontrol (which is what I need to save).
P.S. I tried adding them to a list and then adding the list to the ViewState, but I haven't been able to properly serialize the control. I implemented ISerializable for the userControl's code behind but then it says the ASCX is mot marked as serializable with
Type 'ASP.controls_userControlType_ascx' in Assembly 'App_Web_pn5vxhpw, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable.
I am using the FreeTextBox.dll to get user input, and storing that information in HTML format in the database.A samle of the user's input is the below: [code] I want the HTMLWorker to perserve the white spaces the users enters, but it strips it out.Is there a way to perserve the user's white space? Below is an example of how I am creating my PDF document. [code]
I am trying to have it so that when a user hits a button to enter a shop, it will open a popup window which will have the shop's goods. The only problem is I can't figure out how to keep the variables working between the two windows.
I need to get the variable 'gold' to transfer to and from form2(the shop window) and whatever is bought at the store to transfer back to the main window.
Right now, when I go to form2 all the values are 0, and all the variables I used on form1 are undeclared on form2.
How do I access variables from form1 to show up in form2? Is there an easier way to accomplish this than using a separate form?
Is there a fast way in VB.NET to take a 32-bit int and cast to a 32-bit float while preserving the underlying bit structure? BitConverter will do this, but I'd like to cast it directly without involving byte arrays.
I'd like to hide the contents of a picturebox while still preserving it's imagelocation, width, height, borderstyle, top, left, and sizemod properties. Is this possible?
I am using structures in my programming and I sort the structure according to a value in the structure using IComparer.This is a simple example for what I want.
Dim MyArray(6) As Integer MyArray(0) = 1 MyArray(1) = 45
[code]....
How does number 1 get sorted? Is it brings the newest 1 to top or keeps the old 1in the same index? In my original example (before sorting), MyArray(0) = 1 and after sorting MyArray(0) = 1.Is this the same original 1 or this another 1 (the newest one added to the array) moved to that position?In case the MyArray(0) = 1 after sorting should be MyArray(5) = 1 before sorting.
Here is my a sample of my Code:
Public Structure ToSolve Dim Con(,) As Integer Dim Discharge(,) As Double
[code]....
Using all these methods, how can I preserve the positions of similar number in the list? i.e. I want to bring the newest 'Similar' value to the top of the list.
If I have an existing exception object (I'm not in a catch block, I just happen to have been given an exception object), is there any way (re)throw it while preserving it's stack trace?
The context for asking is that I'm writing a RunWorkerCompleted handler. If an error happened while running the background task, then this will have shown up in the Error property of the RunWorkerCompletedEventArgs. To keep the code simple I want to use the same error handling code to trap this, or any error that happens later during the handler. That means I need code like this:
Private Sub OnDone(ByVal sender As Object, ByVal e As RunWorkerCompletedEventArgs)
[Code]...
I don't think that using an InnerException here (ie. saying something like Throw new Exception(ex)) will work because then I have the problem that my Catch block has no way of knowing whether the exception it's supposed to be handling is the outer one or an inner one. StackOverflow seems to have various similar questions, but I've not found anything that describes this particular situation.
i'm working on a project after returning to coding after four years off and i'm a bit rusty. My problem is that i'm creating a login page and i've got a few people with two last names. in the login box they would put their full name but in the database they have spaces between them. An example would be the name mighel santa anna.
I am using Visual Studio Professional 2008. I am writing a program in Visual Basic 2008 that copies the Used Range from one worksheet to another worksheet, I am able to achieve this by the following code segment:
I need to split a string at all whitespace, it should ONLY contain the words themselves. How can I do this in vb.net? Tabs, Newlines, etc. must all be split! This has been bugging me for quite a while now, as my syntax highlighter I made completely ignores the first word in each line except for the very first line.
I'm having difficulty with some strings of varying 'meaningful' length from a different database (not under my control) that I am trying to trim in my vb.net code.
I only want to remove TRAILING whitespace... therefore, I can't really use .trim method.
The reasoning behind this being that the field sent from the french database usefully uses a <space> to represent a 0 (as you do).
The string is always the same length but the meaningful length can vary, an example being 95WO<space>5CA<space><space><space>...etc
Or it could be this...
<space><space>WO<space><space><space>... etc
Or this...
<space>5WO95CA<space><space><space>...etc
I've got my methods in place to split the string into pairs and perform various lookups but until I can remove the trailing whitespace I'm a bit stuck
I have text like this format "term: 156^^^:^^59 datainput" Or "term: 156^^^:59 datainput" or "term: 156:^^^59" The "^" represented white space. Notice the white space between the the two numbers and the colon. There 2, 3, 4 or even 7 white space between the two number. I want to remove these white space so that the text can be in this format:
Returns a list of customers with whitespace on the end.. very annoying .what can i do to trim in code behind?Also if I bind using the databinding on smart tag is there a way to trim? [code...]
