Trying to figure out XPath and I have successfully create an XPathExpression that lets me grab the events, but any nested sub groups seem to be unavailable to the query, I can get all the children on the Events group, but the LocationName field I can not access.[code]...
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.
Is the following possible in one XPath expression (see sample below) Select all (span tags of class msg) AND all ((img tags that have a non-empty alt attribute) AND (are NOT located inside a span tag of class msg))
Is there an easy way to consume xml to access any of the nodes directly without reading line by line?Here is a sample set of the xml working with. It contains two records of data. I am trying to find a way to load it so if I wanted to get say PostalCode and say Site SID value quickly.
HTML <?xml version="1.0" encoding="utf-8"?><MainSite><MainSites Found="201" Returned="20" Status="0"><Site SID="123456"><Relevance>0.985</Relevance><Title>JDoe</Title><DateModified Date="2010-01-29T01:05:00">1/29/2010</DateModified><DateCreated Date="2010-01-29T01:05:00">1/29/2010</DateCreated><PersonalData><Confidential>0</Confidential><Name><First>John</First><Middle>
I'm running out of walls to bang my head against. Okay new windows form with a textbox, button and TreeView Populate the TreeView.nodes with the default nodes via properties
[Code]...
I want to click button1 and have the name of the childnode? Node3? placed in the textbox. Not via selection, I can do that. But via index or item number. The code I have is as follows
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*
How can we get the text between XML nodes <company> <data id="14" />{<data id="15" />DOCUMENT<data id="23" />pet<data id="24" />DOCUMENT<data id="25" /> </company> I need data between id 23 and 25 (i.e pet DOCUMENT). I have loaded this xml in xmldoc.
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")
and I need to pick node from Id 25 to id 75. It is a portion of XML. Original XML is very long. How to do it without XPath? Dim nodeList As XmlNodeList = xmlDoc.SelectNodes("//Node[@id >" & 25 & " and @id <" & 75 & "]") Dim sb As StringBuilder = New StringBuilder For Each childNode As XmlNode In nodeList sb.Append(childNode.InnerText) Next but it is not working ...
I am able to get the pnode added to the TreeView and all the node breakpoints are hit. The problem is that in the TreeView, I am only able to see the parent view arrow, the rest of the name, image, etc. are not getting displayed. It is like this: How can I fix this?
I am trying to add nodes to a treeview that come from different databases, but at the moment i am just trying to add the first set from the first database.
The link between the child and the parent is the ID column in the parent nodes access database this number is in a column in the child database called Section, i am trying (unsuccesfully) to use queries and If statements.
I am assigning the ID column from the parent database to the .Tag property of the parent node and then i am trying to use an if statement within the query "asking" if the parentNode.Tag = number in section column Then Add new node, but i haven't done it right. The code is below:
While RetVal3.Read If RetVal3(0).ToString = SectNode.Tag.ToString Then Call AddCalcNodes(SectNode)
quick question, i have two treeviews and what i want to do is be able to click on a node in one and have it added to the other. This code doesn't error but it doesn't seem to be doing anything. am i missing something wrong?

I am new to this forum so please be patient with me :-) My problem is how to bring a nested XML structure into a single DataGridView. The XML looks like this:
[Code]...
All I would like to do is populating a DataGridView with 4 columns (Name, Age, Language and Artwork). Each of which containing its appropriate value whereas the latter will contain all pictures... See what I mean?
What I am trying to do is to output a dataset into an xml document using Dataset.WriteXML(), but one of the things that I can't figure out how to do is to have what I believe are called inner nodes.What I mean by that is I have client data, but a client can belong to many companies, which I need to show in the xml as strings, so what I was thinking it should look like is...
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'm using the xmldocument class and I need to check in an RSS document if it includes the optional tags for a news item document. The two main ways that gets passed if via a <dc:creator> tag and an <author> tag below an item tag./rss/channel/item/?I'm new to this. I'd like to see if either of those tags are there, and if them and if not supplant it with something else.Right now in my code if I call /rss/channel/item/author and it's not there I get an error that dumps me. How can I test for it being there before I try something like:
Dim nodes As XPathNodeIterator = navigator.Select("/rss/channel/item/author")
I'm trying to get all nodes below but I am getting an error message of:Overload resolution failed because no accessible 'GetAttributeValue' accepts this number of arguments.[code]
I am trying to add some items to a TreeView Control: TV1.Nodes.Add("key1", "Test1") 'Works TV1.Nodes("key1").Nodes.Add("key2", "Test2") 'Works (Nested) TV1.Nodes("key2").Nodes.Add("key3", "Test3") 'Error (NullReferenceException)
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
