Reading XML Attributes with XmlDocument in C#
When dealing with XML documents in C#, the XmlDocument class offers a convenient way to manipulate and retrieve data. One common task is accessing the attributes associated with XML elements. Attributes provide additional information that can be crucial for your application's logic.
To retrieve an XML attribute using XmlDocument, follow these steps:
- Load the XML Document: Use the LoadXml method to load the XML data into an XmlDocument object.
- Get the Element List: Call the GetElementsByTagName method to obtain the list of elements with the desired tag name.
- Access Attributes: For each element in the list, you can access its attributes using the Attributes property. The attribute you want can be retrieved by specifying its name as a key in the collection.
- Get the Attribute Value: Once you have the attribute, you can extract its value using the Value property.
Here's an example that demonstrates how to read the SuperNumber and SuperString attributes from the XML provided:
// Load the XML document
XmlDocument doc = new XmlDocument();
doc.LoadXml(xmlString);
// Get the element list
XmlNodeList elemList = doc.GetElementsByTagName("MyConfiguration");
// Iterate over the elements and access attributes
foreach (XmlNode elem in elemList)
{
string superNumber = elem.Attributes["SuperNumber"].Value;
string superString = elem.Attributes["SuperString"].Value;
}
Using the Attributes property, you can access any attribute associated with the element, providing a powerful way to extract additional data from your XML documents.

C Polymorphism : is function overloading a kind of polymorphism?
Jun 20, 2025 am 12:05 AM
Yes, function overloading is a polymorphic form in C, specifically compile-time polymorphism. 1. Function overload allows multiple functions with the same name but different parameter lists. 2. The compiler decides which function to call at compile time based on the provided parameters. 3. Unlike runtime polymorphism, function overloading has no extra overhead at runtime, and is simple to implement but less flexible.
What Are the Different Kinds of Polymorphism in C ? Explained
Jun 20, 2025 am 12:08 AM
C has two main polymorphic types: compile-time polymorphism and run-time polymorphism. 1. Compilation-time polymorphism is implemented through function overloading and templates, providing high efficiency but may lead to code bloating. 2. Runtime polymorphism is implemented through virtual functions and inheritance, providing flexibility but performance overhead.
C : Is Polymorphism really useful?
Jun 20, 2025 am 12:01 AM
Yes, polymorphisms in C are very useful. 1) It provides flexibility to allow easy addition of new types; 2) promotes code reuse and reduces duplication; 3) simplifies maintenance, making the code easier to expand and adapt to changes. Despite performance and memory management challenges, its advantages are particularly significant in complex systems.

C tutorial for people who know Python
Jul 01, 2025 am 01:11 AM
People who study Python transfer to C The most direct confusion is: Why can't you write like Python? Because C, although the syntax is more complex, provides underlying control capabilities and performance advantages. 1. In terms of syntax structure, C uses curly braces {} instead of indentation to organize code blocks, and variable types must be explicitly declared; 2. In terms of type system and memory management, C does not have an automatic garbage collection mechanism, and needs to manually manage memory and pay attention to releasing resources. RAII technology can assist resource management; 3. In functions and class definitions, C needs to explicitly access modifiers, constructors and destructors, and supports advanced functions such as operator overloading; 4. In terms of standard libraries, STL provides powerful containers and algorithms, but needs to adapt to generic programming ideas; 5
Polymorphism in C : A Comprehensive Guide with Examples
Jun 21, 2025 am 12:11 AM
Polymorphisms in C are divided into runtime polymorphisms and compile-time polymorphisms. 1. Runtime polymorphism is implemented through virtual functions, allowing the correct method to be called dynamically at runtime. 2. Compilation-time polymorphism is implemented through function overloading and templates, providing higher performance and flexibility.
