VB9 - Using XmlDocument Or Linq To XML So Can Pull Variables - Without Looping

Aug 17, 2010

Visual 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.

Linq To XML - Parsing XmlDocument Within A Soap Evevelope?

Apr 27, 2012

I 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.

Part Serialization Looping Or Even Linq?

Sep 8, 2010

I have a generic dictionary collection with a LOT of data classes, I am serializing this data and sending across IP. I need to cut down this collection into seperate messages as it is too large for my protocol to handle (and I am not changing that!).So, I would love a way to part serialize the data in say 25k (number not size) of classes, but I have not seen this done. I could manually loop through and create 25k lists of this data into new lists and then re-create at the other end, assuming I can use Join or AddRange. There is no GetRange on a collection.Is there a way in linq to select a range from a collection, or any other methods anyone has used?

Linq To Objects - (C#) Creating A Dictionary From An Existing List Without Looping?

Aug 31, 2011

I don't know if this is doable, maybe with Linq, but I have a List(Of MyType):

Public Class MyType
Property key As Char
Property description As String
End Class

And I want to create a Dictionary(Of Char, MyType) using the key field as the dictionary keys and the values in the List as the dictionary values, with something like:

New Dictionary(Of Char, MyType)(??)

Even if this is doable, internally it will loop through all the List items, I guess?

Dynamic Variables In Linq Select Statement?

Nov 23, 2009

I have a listbox that is dynamically filled by certain values depending on what table has been selected from another list box. Once a value is selected, it is being graphed vs a date & time range. With my ignorance of linq: depending on what value is selected, the linq to sql statement I need to create to grab data from my database is different as I can't use an index on an anonymous type.

result = From t In db.APS _
Where t.DateTime >= startDate And _
t.DateTime <= finishDate And t.Weight = weight _
Select t.DateTime, t.TotalConcentration

t.TotalConcentration should be selected if my listbox value is "Total Concentration", but if it's something else, like "Temperature" or "Flow Rate" (connected to appropreate database columns) - this method obviously isn't going to work. I need to be able to dynamically select a specific column from the anonymous type list, or use some other method I'm unaware of to do this.

Write XML Using XmlDocument?

Mar 31, 2010

I'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, 2012

I 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.

Call The XmlDocument.Load Method Asynchronously?

Aug 31, 2011

I 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.

<Location_Y>20</Location_Y>
