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>";

I have this simple string:
string testString = "6/21 <span style='font-size: x-small; font-family: Arial'><span style='font-size: 10pt; font-family: Arial'>Just got 78th street</span></span>";
how do i use the html agility pack to parse out just the text.

i have a problem with my application. I need to pick out a specific text between two nodes. The html page looks like this
<td align="right" width="186">Text1</td>
<td align="center" width="51">? - ?</td>
<td width="186">Text2</td>`
I can pick out Text1 and Text2 with:
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:
<body>
<table>
</table>

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

mySQL_Statement = mySQL_Statement + " AND IDENTIFICATION_DATA.NIIN IN (" + TextBox2.Text & ")"
End If
End If
If astrixState = 2 Then

mySQL_Statement = mySQL_Statement + "AND IDENTIFICATION_DATA.NIIN NOT IN (" + TextBox2.Text & ")"

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?

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.

This may seem simple but for some reason I am having a problem.
I am trying to install SQL Server Express 2005 on Windows XP Service Pack 2 which has not been online for a while.
Everytime I've tried it has told me that it doesn't meet the minimum requirements. I am not sure if its because I am sick and dazed out.

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?

I am preparing string expression to use it to insert statement like
str="insert into franchise (xx,yyy,xxxxx) values (" + rblxx.SelectedIndex + 1 .............
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.
