This is the xml I got as an output from the WriteXmlString() of Infragistics ultrawebtree. I am using this to create another Infragistics ultrawebtree with the same structure. But here I don't want the <Url>something.aspx..</Url>. I want that to be like this <Url><Url>. So how I can able to remove. This I get as a String. So I used Regex.Replace(). But it will work for certain conditions,but for some case it will destruct the xml by deleting some xml tags and xml became not valid due to missing of tags.

View 1 RepliesI have a listview which I am trying to remove the initial root node's indent. My problem seems to be that I can't even set the indent value of the treeview in it's properties lower than 19, and if I try something like:
TreeView2.Indent = 16
16 seems to be the lowest value that makes any visual change.

When you set a label.text to this string it displays it as one long line of code.

I'm using HTMLAgilityPack in a parser that I have up on a server, but I'm having issues with one of the websites that I'm parsing: Every day around 6am they tend to shut down their servers for maintenance, which throws off the Load() method for HTMLWeb, and makes my app crash. Do any of you guys have a more secure way of loading a website into HTMLAgilityPack, or maybe some way to do error checking in C# to prevent my app from crashing? (my c# is a little rusty). Here is my code right now:
HtmlWeb webGet = new HtmlWeb();
HtmlDocument document = webGet.Load(dealsiteLink); //The Load() method here stalls the program because it takes 1 or 2 minutes before it realizes the website is down
How to add a child node to a specific node in treeview?
Say i have "Item1" in treeview already, How do i add "SubItem1" to "Item1" as it's child node?

Basically, it refuses to find the node when the root node contains an attribute.

I am trying to take a string that I have marked up through vb.net code and cross-check it with the text file it came from originally. This is for proofreading the html output.To do this, I need to parse an HTML snippet that does not come from a URL.The examples of HTMLAgilityPack I have seen get their input from a URL. Is there a way to parse a string of marked-up text that does not include a header or similar parts of a well-formed webpage?

How to check whether the content is 'parse-able' before trying to parse it to prevent the error? For now it is an image which makes an error popup however I think it might be just anything which isn't (x)html.
