Searching Nodes From Xml Document?
Apr 4, 2012
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 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 />

Basically im at university and we have a motion capture system. you know the sort. silly lycra suits with dots on them used to animate 3d characters for film etc. this system costs upwards of 70,000 and if you use a prop in your take it generates 2 files which you must edit manually which is a pain if you do it wrong.[code]...

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:

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

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 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?

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'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:
|
|--folder1(tag:folder)
| |--subfolder1(tag:folder)
[code]....
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.

We are opening a Word document from our Visual Basic 2010 application using the Word object. When we run our application under Windows Server 2008 the document name is truncated in the main window title for the document. This is not the case when we run our application under Windows XP. Is there a way to prevent this truncation under Windows Server 2008?Mary Leathem

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 have a function on my program that allows a user to load a listbox filled with words that are matched with words inside a databank. The databank is filled with 2 string arrays and file of .jpg Pictures. The Arrays attached to each word inside the listbox are approximately one page. Each page is two paragraphs of Text(string Array) and one Picture(20Kbytes).My problem is this. When the user selects the option print all, the listbox with approximately 10255 words is selected and begins to fill a Microsoft Word Document.Because the alotted amount of space needed for the MS Word Document is approximately 5 Gbytes,I need to open about 10 Documents and insert the String Array's and Pictures into each document one at a time.Is there anyway to check the filesize of the Open Document before saving the document.This way I could check the open document inside the algorithm for 512 Mbytes of memory and save the document before the size gets above 512 Mbytes.[code]

The application I support is creating an amalgamted Word document by copying couple of Word documents in one document right after each other. The problem is the format of the some of the fields of the document that gets appended is changed in amalgamated document while the amalgamated document is the copy of AppendDocument (imagine if we have one document to copy in the amalgamated document)

I have a XML file that stores information about an application I am trying to read and it looks like this:
<Data> <Login UserName="Username" Password="Password"/> <Application Name="AppName1" Key="Key1" Owner="Owner1"/> <Application Name="AppName2" Key="Key2" Owner="Owner2"/> <Application Name="AppName4" Key="Key3" Owner="Owner3"/> <Owner Name="Owner1"/> <Owner Name="Owner2"/> <Owner Name="Owner3"/> </Data>
After all of the applications are put in I want a list of the owners stored separately like that are. I have my program write it and it works fine but when I try to read from the XML file I get the applications but the separate owners list doesn't read at all. Here is my code that I have:
Dim x As Integer Dim z As Integer '//Declare XML Reader Dim Reader As New XmlDocument() Reader.Load("ProData.xml") '//Try reading Applications Try '//Read Application Element Dim nods As XmlNodeList = Reader.SelectNodes("//Application")
