Remove A Node From The XML?

Apr 5, 2012

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.

LINQ To XML When A Node Does Not Exist

Jun 28, 2009

I was writing a generic class to read RSS feed from various source and to consolidate in one collection of object in VB.net.

Basically the function - using LINQ to XML - is working properly, but I have a problem when the RSS feed I am trying to read does not contain one of the node (as you know, many of them are optional). I would the returned value to be an empty string or nothing, but instead I get a runtime error back. I searched the web for the same problem and I found this post [URL] that apparently explain a workaround, but it does not work with my code.

I am also surprised by the little resources I am finding about this issue, so I am now wondering if I am even putting the question in the right terms...

Following you can find the code:

Dim PostsEnum = From BlogPost In XMLSource.Descendants("item")
Order By DateTime.Parse(BlogPost.Element("pubDate").Value) Descending
Select New Post() With {

VS 2010 LINQ XML - Write To Node?

Jul 2, 2010

After being quite sick of the my.settings-file behavior, I started to create an XML-file (with unique values). Now this works great!!! All my settings, connectionstrings, etc are loaded from an external file and won't be overwritten by the app. itself. But I was wondering how do I save a value/setting? Simple example:

HTML
<test>
<country>Holland</country>

[code]....

read the XML and node:

vb.net
Dim readXML = Xelement.Load(Application.StartupPath & "XMLFile1.xml") ' check if the node isn't empty (crash) If readXML.Descendants("country2).Nodes.Count > 0 Then Textbox1.Text = readXML.Descendants("country2).Nodes(0).Tostring() Else

TreeView - How To Remove Initial Root Node Indent

May 4, 2010

I 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.

.net - Building A LINQ Expression To Find Items Related To All Descendants Of A Tree Node?

Mar 7, 2011

I have built a database structure that represents a category tree to help classify some of the data we have stored. The implementation is that each record in the Category table has a nullable foreign key back into the Category table to represent the parent Category of this category (one-to-many), essentially allowing for subcategories within a broader parent level. There is a CategoryMembership table that links a record in the Item table to its respective Category (many-to-many). I have created the DBML for this database, and it has a member access structure that includes the following:

Remove Linq To SQL Association On Multi-Client DB

Apr 11, 2012

I have a multi-client DB (multitennant) with several tables.Two of these tables are tblEmployees and tblTitles.Now I have a relationship from tblEmployees.empTitle to tblTitles.ttlID.That far everything is working.But now I have to make the application for multiple clients/tennants.So I added the fields tblEmployees.empClient and tblTitles.ttlClient and included them into the association.This works fine for reading and for setting the persons title as well.But if I try to remove the title (set it to NULL), SQL to Linq tries to modify both tblEmployees.empTitle and tblEmploy ees. empClient with is not allowed because tblEmployees.empClient is part of the primary key.And so I get the following error:[code]How can I tell SQL to Linq only to modify field tblEmployees.empTitle???

Doesn't The Union Function In LINQ Remove Duplicate Entries?

Aug 9, 2009

I'm using VB .NET and I know that Union normally works ByRef but in VB, Strings are generally processed as if they were primitive datatypes.Consequently, here's the problem:

firstFile = My.Computer.FileSystem.ReadAllText(My.Computer.FileSystem.SpecialDirectories.Desktop & "1.txt").Split(vbNewLine)
