XPath - How To Get Value Of Specific DIV From HTML
Oct 28, 2011
I'm trying to get the value of a specific <div> from an html. This div has a class attribute of "itemPrice6", but problem is that this class appears few more times for other <div>s in which i'm not interested in. Best thing for me is if I am able to access the needed <div> using something like XPATH so I can target only those I need.
My Code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim web As New HtmlAgilityPack.HtmlWeb
Dim doc As HtmlAgilityPack.HtmlDocument = web.Load("[URL]")
Dim prices As HtmlAgilityPack.HtmlNodeCollection =
[Code] .....
New to VB.net, just trying to figure out how to properly manipulate the asp:Label control.I have a page that, based on if there are results, etc should display an <h1></h1> tag with a header, then the data. As I am using the code-behind model, my user facing page essentially just has the following:
[Code]...
On my code-behind page, I then set the asp:Label and asp:DataList to Visible="true" based on the data from the database. Here's the catch - if there is data, I want to set lblMessage to be an H1, and if not, just standard Label text. I realize I can emulate the look through the CSS, but was just hoping there was another way (maybe similar to the ItemTemplate concept) to specify the HTML type of the Label control - it appears to be a by default.
i have a HTML logs file, the size of this logs is 20mb i need to run a specific logs , the HTML file contain alot of rows almost (50000)rows , it separated by <TR>
when i run a search it should separate each row and chick if it is contain that search log , if so copy it to textbox this what i need when i run a Vb.net application some time work (take log time to finish) and some time stack (stop working) (crash) .... this is my code
my frined have a application in Java and it work much fast but have bad GUI , then i go to VB.net but now the problem is very slow how i can modify the code to overcome this problem ??
I know how to extract an entire page source into VB.NET, but once I do that how do I make VB.NET search the text and return a specific vlaue that is not constant?
I have a simple HTML viewer and I would like to add the capability of searching an open document for a text value I specify. Below is an example I found on MSDN. VB gives me an error, "Selection" is not a member of "System.Windows.Forms.Application".
Private Sub SelectionFind() Dim findText As String = "find me" Application.Selection.Find.ClearFormatting() If Application.Selection.Find.Execute(findText) = True Then
[code]....
What I would like to search is the content of a WebBrowser control.
I want to read a specific line from an html source code. Im storing the source into a string file and i want to read the line X.So im using this method that i found on net
Public Shared Function ReadSpecifiedLine(file As String, lineNum As Integer) As String Dim contents As String = String.Empty Try Using stream As New StreamReader(file)
I'm trying to extract the text fields inbetween the code but the text is always changing so I'm not sure how to keep this dynamic. In put them in to the proper text boxes.
So text box 1 might be Date: then it pulls the date.
and there are multiple listings. so I need it to loop until the end of </table>
How can you find a specific HTML element in a webbrowser.document? I'm making a program that will go to a specified address on the internet and find a html element and get the src link from the element then return the src to the imagelocation of a picturebox. Is this at least possible?
so I had an idea today while modding a game I play. I decided to make a mod-manager.In order to start the game with mods, you have to go to the website, log in, click playnow and view the source of the html file. From there you get the sessionID variable and add it to a shortcut on your desktop. I wanted to be able to automate this process by doing the following:
on button1.click: somehow parse the source of the html file to locate the line that looks like chis: var sessionId = 'random26charSessionID'; and take what is inside of the ' ' and add it to textbox1.text
Any ideas? Not sure if it will be in the same line every time with add banners and stuff...so I wanted to parse the doccument.
I have used .NET and ShDocVw for years to grab data off webpages without any issues I couldn't overcome. This website has me beat though. It seems like such as easy task to grab the titles and other information off a library search page, but I can't see the data to be able to grab it. Usually, I just look in the DOM, but the data wasn't there. I did a view source, but the data wasn't there.
I'm using HtmlAgilityPack to parse HTML. I want to check if an element has a specific attribute. I want to check whether an <a> tag has the href attribute.
Dim doc As HtmlDocument = New HtmlDocument() doc.Load(New StringReader(content)) Dim root As HtmlNode = doc.DocumentNode Dim anchorTags As New List(Of String) For Each link As HtmlNode In root.SelectNodes("//a") If link.HasAttributes("href") Then doSomething() 'this doesn't work because hasAttributes only checks whether an element has attributes or not Next
I use DocTools to Create a Compiled HTML Help File. I want to link to a specific topic in the help file from my program, but the filenames of the html files are generated randomly.
Is there any way to open a CHM to a specific topic by name?
I created a wrapper for DocTools, so I could have the command line piped to a text box and then I could obtain the Topics from there and save them in an INI file that I read when I call the help, but I don't know how to pipe the command line to a textbox.
There seems to be no documentation on the codeplex page and for some reason intellisense doesn't show me available methods or anything at all for htmlagilitypack (for example when I type MyHtmlDocument.DocumentNode. - there is no intellisense to tell me what I can do next)
I need to know how to remove ALL < a > tags and their content from the body of the HTML document I cannot just use Node.InnerText on the Body because that still returns content from A tags.[code]...
I have to pull out particular fields from cells in an HTML table. Using Firebug I was able to get the exact XPath to the cells I need (unfortunately, the cells don't have an id tag). I thought I could use DocumentNode.SelectSingleNode and pass in that path, but it doesn't seem to be working right. What am I doing wrong? Or is there a better approach to this than how I am doing it? Unfortunately, I have no experience with XPath so this is turning out harder than I expected it to be. Here's what I have so far (I know the HTML is particuarly messy, but that's not in my control to change):[code]
I'm currently pulling HTML data from a database and displaying it in a WebBrowser control in my VB.Net application so that it's correctly rendered. The next step is to print it, but I need to be able to send it to a specific printer rather than the default printer. How can I accomplish this?

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 created a method and pass the element type, id, and any inner text that instantiates a new html element. The last statement: Me.Controls.Add(element) adds it to the end of the page, but I would like it to be inserted in a specific position (between 2 divs within a form). What I am describing is very similar to this post on SO here, although it was for javascript.
Usage: Users create pretty HTML news letters in another app. They post the newsletter to the web, but they also want to set the contents of the HTML news letter file as the body of an email and send it using Application In Question. The users understand to use absolute link and image references when sending an E Newsletter. Environment:
AIQ is a VB.Net app deployed via ClickOnce. It is an intranet app; one can be sure MS Office 2003 and the interop 11 dlls are on the target machines.
Restrictions: MAPI is out. It mangles the HTML. Since it is a ClickOnce deployment, we can't register dlls (I think, correct me if I am wrong). Therefore CDO and COM is out (again, I may be wrong.... I would be happy to be proven so).
I have the following 2 lines of code:[code]I'm looking to get the value for first instance of lastWriteTime which should be 2011-10-13T10: 48: 48. 3833771-04:00 but the code just pops up an empty string. Sorry for the big post but here is the entire XML file for reference. Can anyone see why this isn't working, or give me an example of how to make it work some other way? [code]
I have an XElement and an XPath expression that selects a node from it. It works fine in the original program that I wrote it in but doesnt work if I paste it to another program. I've checked the references and import statements.
I think the problem might be that the original program had the code within the class of a wpf window while it was moved to a abstract class where it doesnt work.[code...]
I have a XPath expression that is supposed to return/get only one node out of the XML document. But it is getting more than the one. I don't understand why.
Code-behind:
Dim xmlNameTbl As XmlNameTable = rootDoc.NameTable Dim xmlNS As XmlNamespaceManager = New XmlNamespaceManager(xmlNameTbl) xmlNS.AddNamespace("asp", "http://test.com/asp")
There are multiple occurances of the PLUS_BORROWER data. For each occurence of PLUS_BORROWER, I want to save the CREDIT_SCORE and DAYTIME_PHONE_NBR when the Type= And SOCIAL_SECURITY_NBR are certain values. Then I want to execute a loop and extract the Credit_Score and Daytime_Phone_Nbrs.
I have the following code that will pull off the first PLUS_BORROWER if the Type='Primary', but I am having trouble expanding it.
oExtraData.Load(myXMLFile) 'only select nod with type attribute equal primary Dim oNode As Xml.XmlNode = oExtraData.SelectSingleNode("//PLUS_BORROWER[@Type='Primary']") 'get credit score node Dim scoreNode As Xml.XmlNode = oNode.SelectSingleNode("CREDIT_SCORE") MsgBox("I have the Primary") MsgBox("Credit score is " & scoreNode.InnerText)
