[C# .Net] Reading XML Attributes


Question

Hey,

I tried searching for information but couldn?t find any useful information.

Does anyone know how to read Attribute strings using XMLtextreader?

 <?xml version="1.0" ?> 
- <Notes>
  <Note ID="903410613" text="test" x="20" y="33" pin="false" opacity="255" /> 
  <Note ID="903415410" text="test" x="60" y="443" pin="false" opacity="255" /> 
  <Note ID="903418395" text="test" x="43" y="450" pin="false" opacity="255" /> 
  </Notes>

Thanks for any information.

Example from MSDN:

//Load the reader with the XML file.
       reader = new XmlTextReader("attrs.xml");
  
       //Read the genre attribute.
       reader.MoveToContent();
       reader.MoveToFirstAttribute();
       string genre=reader.Value;
       Console.WriteLine("The genre value: " + genre);

If that doesn't do what you want, check out the XmlAttribute and XmlAttributeCollection classes

edit: I got exceptions with your file until I changed the top line:

<?xml version="1.0" encoding="utf-8" ?>
<Notes>
    <Note ID="903410613" text="test" x="20" y="33" pin="false" opacity="255" />
    <Note ID="903415410" text="test" x="60" y="443" pin="false" opacity="255" />
    <Note ID="903418395" text="test" x="43" y="450" pin="false" opacity="255" />
</Notes>

Well I have a bit of it working,

           XmlTextReader reader = new XmlTextReader("notes.xml");
            reader.ReadStartElement();
            reader.MoveToContent();
            reader.MoveToAttribute("text");
            string ID = reader.Value;

It only scans the first line though. I need it to scan every line for the "text" value.

Any idea? :unsure:

Just use a loop to, err, loop through each line. And use XmlDocument/XmlNode/XmlAttribute - I find it much easier. I haven't tried this code, but it should work (I hope):

XmlTextReader reader = new XmlTextReader("notes.xml");
XmlDocument doc = new XmlDocument();
doc.Load(reader);

XmlNode baseNode = doc.DocumentElement;

foreach (XmlNode node in baseNode.SelectNodes("/Notes/Note")
{
  // Do something here.
  Console.WriteLine(node.Attributes["text"].Value + "\n");
}

well MoveToAttribute returns a bool.

while ( true == reader.MoveToAttribute("text") )

{

//blahblah

}

Get into the habit of putting constants on the left of the comparison operator, that way you will never have logic errors with confusing = with ==. There will be a compiler error if you have = instead of ==. If the constant is on the right side and you do a =, it will compile and you'll never know.

    • Windows 11 is getting a useful new audio feature by Taras Buria Photo: phamtu1509 Windows 11, in its current form, does not offer a quick and easy way to play audio over more than one device. If you have a bunch of audio devices connected and you want to play music on all of them, you have to tinker with third-party software to make it work. Apparently, Microsoft wants to change that with a new feature coming soon to Windows 11. @phantomofearth, the ever-giving source of Windows insights, discovered that the latest Windows 11 preview builds have a hidden toggle in quick settings that lets you share audio to multiple devices with just a few clicks. All it takes is clicking "Shared Audio" in the control center, selecting two or more available devices, and pressing "Share." As usual, there are no official announcements yet, so details about this feature remain unknown. Still, you can probably expect the new shared audio feature to make it to a Windows 11 preview build in the near future. In other Windows Insider news, Microsoft recently revealed that one of the recent taskbar changes was pulled from the operating system due to negative feedback. The company experimented with a simplified taskbar tray area, but later decided to nuke it because people did not like it. Still, there are plenty of other features coming soon to Windows 11. Check out our recent top 10 list here. Hopefully, all of them will make it to the Stable channel soon.
    • Chinese? It sounds extremely dangerous. I’ll reconsider buying a Meta Quest 3.
    • - What's your salary? Is it more than $100k a year? - Nah, it's $100 mil a year.
    • Compared to my ear buds which are the size of a matchbox, cover a much broader frequency range, and work everywhere without setup? Yeah, still not buying this as a replacement.
    • Meta's Superintelligence team staffed by 50% Chinese talent, 40% ex-OpenAI by Hamid Ganji Mark Zuckerberg's latest big bet at Meta involves building a team of the best AI superstars in the market to lead the so-called Superintelligence Labs. The goal of this team is to develop AI models that will ultimately lead to Artificial General Intelligence (AGI). AGI refers to an AI model with capabilities comparable to, or even beyond, those of the human brain. Achieving human-level cognitive abilities with an AI model requires substantial investments, as well as hiring the best talent to build such a system. That's why Meta is throwing hundreds of millions of dollars at AI researchers from OpenAI, Apple, and other companies to recruit them for its Superintelligence team. A user on X has now shared a spreadsheet that provides us with some unique insights into Meta's Superintelligence team and the origins of its 44 employees. The leaker claims this information comes from an anonymous Meta employee. The listing claims that 50 percent of the staff at the Superintelligence team are from China, which demonstrates the significant role of Chinese or Chinese-origin researchers in Met's AI efforts. Additionally, 75 percent of these staff hold PhDs, and 70 percent of them work as researchers. Interestingly, 40 percent of the staff are ex-OpenAI employees whom Mark Zuckerberg poached from the maker of ChatGPT. Additionally, 20 percent of Meta's Superintelligence team members come from Google DeepMind, and another 15 percent come from Scale AI, a startup that Meta recently acquired in a $15 billion deal. Another interesting point is that 75 percent of the Superintelligence team are first-generation immigrants. The leaker claims that each of these employees is now earning between $10 million and $100 million per year, although Meta still needs to confirm these substantial figures. However, it has already been reported that Meta is offering up to $100 million in signup bonuses to poach the best AI talent from OpenAI and other rivals. The revelation that half of Meta's Superintelligence team consists of Chinese nationals could trigger concerns within the Trump administration and Congress.
