i want to select specific nodes of a xml document.Everything is ok until the document has an xml namespace. Then when i try to select the specific nodes no node is being returned.. This is because an xml namespace is declared. Is there a way to select those nodes and ignore the xml namespace ?
The file is :
<?xml version="1.0" encoding="utf-8"?>
<xliff xmlns="urn:oasis:names:tc:xliff:document:1.1" xmlns:tek="http://www.tektronix.com/TC" xmlns:cals="http://www.tektronix.com"

I have an XML file and I have a function to which this XML is passed as string. I have loaded this string in Xmldocument and I need to insert few children nodes under one node. This function returns the modified XML string. I want that whenever this function is called, new child nodes are added, currently, It adds child nodes once.Do I need to overwrite the XML file ? If so, How can I replace the node with new node ( with new child nodes added) so that It has child nodes added before the function is called again ?
My code looks something like this:
Dim doc As New XmlDocument
doc.LoadXml(applicationXml)
Dim parentNode As XmlNode = doc.GetElementsByTagName("prList").Item(0)

I'm all new to this treeview business. I have a fixed treeview, very simple and basic. Only two levels, parent and child nodes. I just need two things out of this treeview.
1) If parent is checked, check all child nodes.
2) If just one child node is unchecked, uncheck parent node.
That's it! I've been looking for this for 30 mins and I cant find it. Maybe because my vb.net is old, it doesnt seem to be the same as others =/ I'm using vb.net 2003.

I have a treeview that is populated from a HDD folder collection. Its structure is similar to the following (however the structure is dynamic):
My Disk:

I call the sub as follows:
deleteNode(treeview1.Nodes(0).Nodes)
However, the above is not working properly. It deletes only some nodes and not all the targeted nodes.
I'm trying to do some simple XML manipulation by searching one XML file for a set of nodes and inserting them into another XML file at a specific location.I'm able to succesfully create a node list from one of the files using the following xpath statement [code].....
I'm struggling to see how I can easily select any node I want within the first XML file but the second file refuses to play ball! I've attached the second XML file should anyone wish to check that I've interpreted the structure correctly.
I need to be able to delete some XML nodes from an XML file but i'm not quite sure how. I need to delete all entires in the second <Launch.Addon> node but it won't always be the second entry. There may be other nodes before it.

I decided to use XML to handle some of my configuration chores. My XML file looks something like this:
<catagories>
<catagory path= "C: empwyoming" name="Wyoming">
<URL Filename="Picture1.jpg">http://www.domain1.com/pic.jpg</URL>
<URL Filename="Picture2.jpg">http://www.domain2.com/pic.jpg</URL>
[code]....
I'm wanting to manage this list in my program. Currently, I have written code to read the catagories into a combo box, and once a catagory is chosen, I can read the children URL nodes into a listview. I want to allow editing and re-arranging of the URLs in the listview, and I'll have no problems with that. So my question is, what is the best way to dump the listview back to the xml file? You should consider the contents of the listview as a replacement for ALL of the existing children in the XML file.
how to add treeview nodes and sub sub nodes using functions
View 1 RepliesI now have a similar xml problem. Now that I can create and add to the file, I only have two more problems to solve.
1) How do I remove all nodes (without starting over from scratch, hopefully)?
2) How can I limit the number of nodes in the xml file?
That should do it (for now at least) until somebody wants some other feature.[URL]..
Alright, I decided instead of Serialization or Access, I'm going be using XML files.
Now, I have them properly adding and editing, but I see theirs a property .SelectNodes( )
How do I use this ? I did a quick Google Search, couldn't find much. Here's the current Code I'm using to Edit my Document.[code]...
