View 11 RepliesCall The XmlDocument.Load Method Asynchronously?
Aug 31, 2011I have working code to read an RSS feed that uses:
Dim doc As New XmlDocument
doc.Load("http://...")
Dim channel As XmlElement = doc("rss")("channel")
Dim items As XmlNodeList = channel.GetElementsByTagName("item")
Unfortunately the doc.Load call causes the rest of the program to become unresponsive until it finishes.What's the best way to perform the load asynchronously and have a callback function to process the data?Edit: Here's the code I've tried using WebClient - the Load method is still lagging:
Private Sub checkResults()
'request rss feed
Dim w As New System.Net.WebClient
[code]....
The rssReadCallback method is executed fairly quickly after calling checkResults, but then the UI freezes during the Load method.

Using GetElementById When The Target Element Doesn't Have An ID
Sep 19, 2011ok, so i want to invoke a click on this element
<div class="round spacer listTitle" onclick="Travian.Game.RaidList.toggleList(5101);">
however, this doesn't have an ID so i can't simply use GetElementById. if i were in JS i would use a 'GetElementsByClassName' and then set an index to find the element i want to use but i am not sure if vb.net has such a function so i thought about trying to call its parent element which does have an Id but this does nothing.
webBrowser.document.GetElementById("list5101").InvokeMember("click")
i have also tried using the 'GetElemenetsByTagName' (i actually was using this thinking it was a GetElementsByClassName which is probably why it didn't work, whoops) so i was thinking about using GetElementById to locate the parent element, list5101, and then if possible find the child node i want and triggering it like that. or maybe i could just call the javascript function outright ?

The object is this situation, does exist. Error is caused at: document.getElementById line.What else could be causing the error?

Write XML Using XmlDocument?
Mar 31, 2010I've reached a point where it's time to learn how to Read/Write XML files properly and I'm really confused to how we're supposed to do this. I've been reading up on using the XmlDocument, but all I'm finding is how to use it to read xml files. Right now I need to Write them, later I'll code the reading of them.
The data for the XML file comes from a couple of tables in a database too, I've got a Master/Child table (actually there's 5 child tables). I've got the data coming into DataTables and I've got the loops set up already, I'm just stuck to how do I take the Master table's row and store that data as an XmlNode then loop each of the 5 child DataTable's and add each row as a child node to the master's node.

Asp.net - Add XML Nodes To Specific Node In XmlDocument?
Jun 19, 2012I have two XmlDocuments that both have a namespace attribute specified. Both documents have the same structure, but contain different data. I can't seem to get a specific node tree from one document added to the end of the same node tree in a second document. Here is an example of my two documents:
Document #1:
<?xml version="1.0"?>
<rootnode xmlns="http://www.mynamespace.com/Service/2012-06-18">
[code]....
I certainly know this is wrong... I've tried serveral different approaches. This particular approach adds all <Item> nodes to the destination document, but it adds them to the very bottom of the document instead of after the last <Item>. how to add a specific node tree an XmlDocument to a specific position in another document? Again, there is a namespace involved and the <Item> nodes have nested nodes/elements under each one.
NOTE: The <Id> nodes have example data to show uniqueness only. I can never count on any kind of numbering. The order of each <Item> node is totally unimportant. I'm just assuming it will be easiest to add additional <Item> nodes after the last one in the destination document.
