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.

I want the title attribute of the node but it gives me a message box instead saying: "System.Xml.XmlAttribute" How can I convert that or in some other way get the title attribute of the books?

VB9 - Using XmlDocument Or Linq To XML So Can Pull Variables - Without Looping
Aug 17, 2010Visual Studio 2008. .NET 3.5 VB 2008 or VB9 as it is also called. I have an XML file that I need to parse efficiently. I had completed the project by means of pulling the document into an array and pulling the variables I needed via looping through the array. This turned out to be very inefficient as the file is quite large.
I am now looking into using XmlDocument or Linq to XML so that I can pull the variables that I need without looping. I read that Linq is the fastest so I was trying to go that route.
I have searched all over the place for examples of parsing xml documents and I can't find exactly what I need.
My XML file is formatted somewhat like this:
Code:
<Folder>
<set>
[CODE]............
The idea is that I need to get those <fp> values for certain f_types only. Not only that, but it also needs to <set> specific. You will notice that the second "<set>" has a <num> Value of 2 within the <data> tags.
So... I need to find a way to search for say all the <fp>'s in set one that are of f_type 5 only, exlcuding all of set 2's f_type 5. This XML is not ideal but re-formatting the XML is not an option for me. I have to work with what I got.
After hours of googling all I was able to do was pull all the Element values for each <F> child nodes if they included a f_type value of 5. But... It does it for the whole doc, not just the 1st set like I need.
I will post what I have so far: It is not much but I can't find great info on using Linq to xml that does what I am trying to do.
[Code]:.....................
This doesn't even need to be enclosed in an XML block but for some reason it wouldn't work unless I put it into XML block.
.net - Why Does XmlDocument.LoadXml Throw System.Net.WebException
Sep 12, 2011Why does System.Xml.XmlDocument.LoadXml method throw System.Net.WebException ?if MSDN was right, LoadXml should at most give me a System.Xml.XmlException.Yet I have weird exceptions like:The underlying connection was closed: The connection was closed unexpectedly.

Asp.net - Make XmlDocument Work With XML That Does Not Have The Attributes Quoted?
Sep 8, 2011I have an asp.net vb project that needs to parse some raw XML that is coming out of a database the XML is laid out like this:
[Code]....
I know that the error is because the attributes are not quoted. Is there anyway to make XmlDocument understand the attributes anyway or an easy way to use a reg expression to add quotes to the attributes before loading the string into the xmldoc?
Call 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.
Linq To XML - Parsing XmlDocument Within A Soap Evevelope?
Apr 27, 2012I need to get a list of the item id attribute in a soap packaged XML file, in the example below ref-2 ref-3, but I'm having a problem finding examples that work and not even sure where my attempt at a linq to xml statement is failing. Are there any good examples of parsing a XMLDocument in a SOAP envelope or am I just making this way harder than it needs to be.

Parsing Size And Position Objects From A XmlDocument?
Aug 26, 2009Is there more elegant syntax for reading/parsing Size and Point objects in an Xml document?
Source Xml Nodes:
<objSize>{Width=64, Height=64}</objSize>
<Location_X>20</Location_X>
<Location_Y>20</Location_Y>
[Code].....
I have control over both the source nodes and the parsing code... So I am just being too lazy with my XmlNode creation? Regardless is there any benefit to using XmlConvert v.s. using integer.parse (or .tryparse)?
Retrieving Data From Xml Using XmlDocument, XmlNode And XmlNodelist?
May 25, 2012This is a sample code in vb.net in which i retrieve the details of elements without attributes.

For Each baseDataNode As XmlNode In baseDataNodes

How can i retrieve the details of the xml like having node with attributes and its child also having attributes. I need to retrieve all the attributes of node and its child node which are present in the middle of other xml tags.
Xml - Save Updated XMLDocument As A String (.net Or Other .net Lang.)?
Mar 28, 2011I have an XMl string in a Field of a mySQL Table. I load an XMLdocument (xmlDoc) from that string
I then Search for a node and change an attribute. All good in here.Then I want to save changes that i made to the XMLDocument in string format so i can update my table in the DB.
How can I do this.?
If I execute xmldoc.save(), well, it will save a XML file. How can I save the changes that I have made but instead of savig the file, save it as a string so I can save it in my table.I really do not want to parse the XML string as a normal string to search my parameters and save it.
I am working on vb.net, but if you have code in other .net lang, no problem.The DB is in MySQL

View 1 RepliesXmlDocument.Load: Unexpected End Of File Has Occurred?
Jun 21, 2010I'm attempting to load an xml document from an XML column in MSSQL 2008, into an XmlDocument (see code below).
Sometimes the code will break at the xdoc.Load(xr) line with the error "Unexpected end of file and occurred". After breaking, the XmlReader has a value of "None".
While researching the problem, I saw posts that referred to a 4Kb limit on StreamReaders and figured this may be related somehow. So I cut down the size of my document (to around 4Kb) and everything worked fine.
On average, the XML documents I'm importing from the database are 20Kb.
