C# - Concatenate Two Nodes When Using The HTML Agility Pack In App's?
Oct 29, 2010
I am using the agility pack to do some screens scraping and my code so far to get titles is:
foreach (HtmlNode title in root.SelectNodes("//html//body//div//div//div[3]//div//div//div//div[3]//ul//li[1]//h4"))
{
string titleString = "<div class="show">" + title.InnerText + "</div>";
shows.Add(titleString);
}
Before the title I want a timestamp related to the title and it has the node /html/body/div/div/div[3]/div/div/div/div[3]/ul/li[1]/ul/li/span. How can I get this value next to the title? So something like: string titleString = "<div class="show">" + time.InnerText + " - " + title.InnerText + "</div>";
HtmlNodeCollection cols = doc.DocumentNode.SelectNodes("//td[@width='186']");<br /> foreach (HtmlNode col in cols)<br /> { if (col.InnerText == "Text1") { Label1.Text = col.InnerText; } }
The reason why i have the if-condition is because there are more td's in the page. And i need to specifically pick out the one who got "Text1" in it. But the problem is how i can parse out the text "? - ?" There are more text in the document also having the text "? - ?" but i need to pick out specifically the one between my two other nodes. The result should be Text1 ? - ? Text2 etc. I guess it has something to do with nextchild or sibling etcetera?
I am attempting to replace this god awful collection of regular expressions that is currently used to clean up blocks of poorly formed HTML and stumbled upon the HTML Agility Pack for C#. It looks very powerful but yet, I couldn't find an example of how I want to use the pack which, in my mind, would be a desired functionality included in it. I am sure I am an idiot and cannot find a suitable method in the documentation. I had the following html:
<p class="someclass"> <font size="3"> <font face="Times New Roman">[code]....
When I utilize the HtmlNode.Remove() method it removes the node plus all it's children. Is there a way to remove the node preserving the children?
I am creating an HTML document using HTML agility pack. I load a template file then append content to it. All of this works, but when I view the output file it has removed the closing tag from my <br/> tags to look like this <br>. What is causing this?
Dim doc As New HtmlDocument() doc.Load(Server.MapPath("Template.htm")) Dim title As HtmlNode = doc.DocumentNode.SelectSingleNode("//title") title.InnerHtml = title.InnerHtml & "CEU Classes" Dim topContent As HtmlAgilityPack.HtmlNode = doc.GetElementbyId("topContent") topContent.InnerHtml = html.ToString doc.OptionWriteEmptyNodes = True doc.Save(outputFileName, Encoding.UTF8)
More info:
It was removing my closing image tags, after I added doc.OptionWriteEmptyNodes = True, it quite doing that.
How can I loop through table and row that have an attribute id or name to get inner text in deep down in each td cell? I work on asp.net, c#, and the newest html agility package.
An html file have several tables. One of them has an attribute id=main-part. In that identified table, there are many rows. Some of those rows have same attribute name=display. In those named rows, there are many columns which I have to extract text from. Something like this:
I want to parse and page that takes POST parameters. like this is my scenario. i have to parse some search results. but the search parameter are sent in post body to that page. To parse the search result i have to send parameters to that page in POST. how i can do that with agility pack ?
i need to concatenate the html tag like <br/> and to the textbox.text in asp.net textbox. i have used this txtMessage.Text + <br/> + strgetlist; but it is displaying TaskName<br/>Project1,project2.. how to give break and space between thest two.
what it should output is my enable image with the text on the right saying 'enable' if i only have Text='<img src="app_images/enable.png" />' i have the image, just a question of how to add the resource entry at the end of it...
convert the code below to LINQ, converting my project to a wseb version usimg LINQ To SQL. The project contains 10 textboxes to possibly select from, but I'm only providing the first two textboxes to simplify my question.
mySQL_Statement = "SELECT IDENTIFICATION_DATA.NSC,ITEMISCD.RNC,ITEMISCD.NSC1 FROM IDENTIFICATION_DATA LEFT OUTER JOIN ITEMISCD on IDENTIFICATION_DATA.NIIN = ITEMISCD.NIIN" If Not ((TextBox1.Text = String.Empty) And (TextBox2.Text = String.Empty) Then mySQL_Statement = mySQL_Statement + " where " If Not (TextBox1.Text = String.Empty) Then mySQL_Statement = mySQL_Statement + "IDENTIFICATION_DATA.NSC IN (" + TextBox1.Text & ")" End If If (TextBox1.Text = String.Empty) Then mySQL_Statement = mySQL_Statement + "isnull(IDENTIFICATION_DATA.NIIN) = FALSE" End If If Not (TextBox2.Text = String.Empty) Then If astrixState = 0 Then If Not (TextBox1.Text = String.Empty) Then mySQL_Statement = mySQL_Statement + " AND IDENTIFICATION_DATA.NIIN IN (" + TextBox2.Text & ")" ElseIf (TextBox1.Text = String.Empty) Then mySQL_Statement = mySQL_Statement + " AND IDENTIFICATION_DATA.NIIN IN (" + TextBox2.Text & ")" MsgBox(mySQL_Statement) End If End If If astrixState = 1 Then If Not (TextBox1.Text = String.Empty) Then mySQL_Statement = mySQL_Statement + " OR IDENTIFICATION_DATA.NIIN IN (" + TextBox2.Text & ")" Else mySQL_Statement = mySQL_Statement + " AND IDENTIFICATION_DATA.NIIN IN (" + TextBox2.Text & ")" End If End If If astrixState = 2 Then If Not (TextBox1.Text = String.Empty) Then mySQL_Statement = mySQL_Statement + "AND IDENTIFICATION_DATA.NIIN NOT IN (" + TextBox2.Text & ")" Else mySQL_Statement = mySQL_Statement + " AND IDENTIFICATION_DATA.NIIN NOT IN (" + TextBox2.Text & ")" End If End If End If
I have a code that load hierarchy( nodes) into trew view.. by selecting different date, the hierarchy result from SP will show in the treeview..
the problem is even though I select a different date.. the result( node) of previous date is still showing in addition to the new hierarchy result...
it;s like the new result node is appended to existing node.. instead of refreshing the node and showing only the new result. How can I clear out the treeview nodes before adding new nodes from different date?
I have a page where I have a button and a read only text box, and the button uses javascript to open a popup window with a date picker on it, which is used to set the text box. Here is my button code:
We are developing a web site and in this site we have a link to a clickonce deployed application. This is a direct link to the executable (Remote share execution). For this to be possible the client must have .NET framework SP2 installed. The problem is i need to get the SP version of the clients machine. I can access client information using Request.UserAgent but this doesn't have a clue about the service pack.
I want to execute my asp.net application where Windows XP Service Pack 3 is installed + VS 4.0 framework is installed and IIS 5.1 is installed. The program is not running yet. It shows me an erro message that "Server is unavailable" Is it possible to run the application on this machine. I also tried aspnet_regiis -i and -c command
I am working on an application that requires a lot of data sets being sent to the client when application starts. To avoid multiple trips to the server I want to combine all the data together and send it as one piece. I cannot build one single SQL statement, it's going to be many. Should I just put SQL results together like strings?
when I do so it simply concats the thing like value of rblxx.SelectedIndex "0" and 1 makes 01 and not 1.suggest some function and trick to add the numeric values not concat. I tried using System.Convert.ToInt32 but not worked for me.
