Read The Document And All Of Its Child Nodes?
Apr 12, 2012
I have an xml document similar to the what's below.I'm wondering how I can read the document and all of its child nodes.I want to only read the parent node called MYTYPES and disregard MYGRAPH. The code I am using reads the document but only prints out the parent node (Type1 and Type 2, in this example).How do i get all the child nodes, and their children. For example, i would like to print out:
Type 1: Clarion, 10. Pittsburgh, 20
Type 2: Trention, 10. Harrisburgh, 20

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.

OK, so I have the code to add a Child Node to a selected node in ta TreeView. The thing is, even if I select a child node to "add" to, it adds the new node to the parent of the selected child node.
I know why it does that: TreeView1.Nodes(TreeView1.SelectedNode.Index).Nodes.Add() adds to the first node. So how do I progamatically add to the child node I have selected, not it's parent node. I can't figure out the logic on how to accomplish this.
NOTE: There can be an infinite amount of child nodes.
UPDATE: I just found out that if I have a child node selected, TreeView1.SelectedNode.Index returns -1 since there is nothing selected in that first level. I'd have to use TreeView1.Nodes(0).SelectedNode.Index to get the proper index for the ChildNode. *sigh*

I hope someone can steer me on the right track for resolving this. Basically, all I want to do is create a node list from one xmldocument and then insert the result of that xpath query into another xmldocument at a specific place. I thought this would be quite straightforward but I'm running into problems re the node attributes. This is what the xml looks like for the source and destination files
Source File :
<?xml version="1.0" encoding="UTF-8"?>
<Application version="1.5" hwrEnabled="true">
<Name />
<Description />

I am currently stuck on searching an xml document to find a single node so that i can insert edit changes from a ui to the text of the node.
[Code]...
What i am doing is i have a drop down menu on a ui that a user selects a query and then the query text is displayed for editing. When the user clicks the save button it will take the edited query and replace the text of the original query. The only problem i am having is i can't find any example of how to do an xpath to find the selected query from the drop down menu.
Dim QueryText As XmlNode = QueryList.XMLDoc.SelectSingleNode("/Queries/Query/Text")
This gets the text of the first query but i need it adjusted to search the xml document for whatever query the user has selected... once i get the path able to find the selected query i should be able to finish this devil of a task.

I'm simply trying to merge 2 xml documents (adding nodes from one into the other). I've done some Google searching, and tried a few things, but I always get the same error "The node to be inserted is from a different document context" I'm sure I'm missing something simple, just seems like this should not be that difficult. Here's my code:

What would be the fastest way to put XML nodes in memory? I can use generics, arrays, list arrays and so on but how to get the nodes first? All of the following are taking too long:
XmlDocument.Load
XmlDataDocument (used it by accident)
XPath.XPathDocument("path")
I can loop through 500 000 Nodes and get the 30 000 uniques in less than a second instead of 3 hours previously but loading the nodes takes whole 20 seconds. Never thought this would be the bottleneck.

I have the following code which checks for the value of the 'cc_supplier_status' column for each of the rows in my table. If the state is 0, I need a child node to be added to a node named 'Inactive Suppliers' in my tree view (tvw_Supplier) with it's text being the value of the 'cc_ supplier_ name' value for the same row.If the state is 1, a child node is to be added to a node named 'Active Suppliers'.If the state is 2, a child node is to be added to a node named 'Pending Suppliers'.The code I have now just filters out the status value for each row, and performs a select case on it. I need to know how I'd add a new child node to the parent nodes mentioned above.[code]

I have a bunch of XML's that need to be put into an SQL database. One XML represents all orders for a certain department of a store. The problem (for me) is that in one XML there can be (and are) multiple orders (called distributions in my case.) The XML looks as follows (truncated):
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<order><process_id>322867</process_id>
<key1>RET</key1>
<key2>40_134985</key2>
[code]....
So in this example I have two 'distributions'. Now I can get all data out of the XML fine, which I do like this:
get xml data
awsFeed = XDocument.Load(fileName)
Dim orders = From order In awsFeed...<order> _
[code]....
However, in this case my SQL input would have to result in 2 entries, because there are 2 orders. Both entries would have the same data, except for different entries. I know how to post to SQL, that's not the problem. My real problem is, how do I 'loop' it through the XML. I think i'm looking for something like:For each 'distribution' in orders -> put into array.Or something like that. After that I could query the array and put it in the database.

I know how to add a single node to a top level node in an XML document, but I cant figure out how to add multiple (nested) nodes to another node. For example, I want to add this node structure to node called "PaymentInformation":
<Prepaid>
<BillShipper>
<AccountNumber></AccountNumber>
</BillShipper>
</Prepaid>
Do I have to add each node separately or can I add them all at once?

adapted from Major treeview/list view head ache I managed to make the treeview display the folder and the sub folders... but it isn't very hierarchial. Check attached pictures. Image1 shows how it is and image2 shows how I want it to be. Can anyone tell me how to get it to look like image 2?...Image2 was made in Windows Explorer. Image1 is a screenshot of the runing program that I am trying to make. I have been googling around but no luck so far. Practically I think what I shoul be asking is how to create child nodes of subfolders. The program is going to copy whatever the user checks in the treeview into another folder chosen by the user. I am using Visual Basic 2008 Express.

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)

Most of my treelist code is working ok, however I would like to produce two arrays of string, one which contains all the parent nodes in a Treeview, and the other with all the child nodes. I'm obviously doing something stupid as I have "Object reference not set to an instance of an object." I'm not declaring something.
This is my attempt:
Private Sub listbuilder(ByVal nodelist As TreeView)
Dim parentlist() As String
Dim childlist() As String
Dim j, n As Integer

I'm new to this Visual Basic stuff. I have TreeView under the name of TreeView1 and it has two Parent nodes, one is Library and the other is Store. Under Library and Store I have childnodes and thats were I'm stuck. For example under Store there is Downloads and Apptrackr.
What I want is when a user clicks on Apptrackr it runs this piece of code
WebBrowser1.Visible = true
DownloadsBrowser.Visible = false
And when the user clicks on Downloads it then does the opposite
WebBrowser1.Visible = false
DownloadsBrowser.Visible = true
