How to open xml format
Use most text editors to open XML files; if you need a more intuitive tree display, you can use an XML editor, such as Oxygen XML Editor or XMLSpy; if you process XML data in a program, you need to use a programming language (such as Python) and XML libraries (such as xml.etree.ElementTree) to parse.
How to open XML format? This question is awesome!
Many newbies will be scared by XML, a seemingly complicated guy, but in fact it is not that scary. We broke this article and completely figured out what XML is and how to open it gracefully. After reading, you can not only open the XML file, but also have a deeper understanding of its structure and purpose, and even write your own XML parser (of course, this requires further learning).
Let's talk about what XML is first
XML, full name Extensible Markup Language, is an extensible markup language. To put it bluntly, it is a text format used to store data. Not as concise as JSON, XML uses tags to wrap data, has clear structure and clear hierarchy, which is a bit like HTML, but is more general and flexible than HTML. It does not have predefined tags, you can customize tags to describe your data, which is what "scalable" means. This gives XML great flexibility and can be used to represent a variety of data, from configuration files to database data, easily handled.
Opening an XML file is actually very simple
What advanced tools do you think you need to open XML files? In fact, most text editors can be opened directly. Notepad, Sublime Text, VS Code, and even any code editor you like can directly display the contents of the XML file. Of course, these editors simply display text and will not help you parse the XML structure.
Want to open it more gracefully? Try the XML editor
If you want to see the structure of the XML file more intuitively, it is recommended to use a dedicated XML editor. This type of editor will help you display the XML file in a tree structure, allowing you to see the relationship between each tag and data at a glance. Oxygen XML Editor and XMLSpy are good choices, which provide powerful XML editing, validation and conversion capabilities. But they are usually paid software.
Programmatically open XML? This is the path to masters
If you need to process XML data in a program, you need to use programming. Mainstream programming languages such as Python, Java, and C# all provide rich XML parsing libraries. I personally prefer Python because it is simple and easy to use. Here is a Python example, using the xml.etree.ElementTree
module to parse a simple XML file:
<code class="python">import xml.etree.ElementTree as ET xml_data = """ <bookstore> <book category="cooking"> <title lang="en">Everyday Italian</title> <author>Giada De Laurentiis</author> <year>2005</year> <price>30.00</price> </book> <book category="children"> <title lang="en">Harry Potter</title> <author>J K. Rowling</author> <year>2005</year> <price>29.99</price> </book> </bookstore> """ root = ET.fromstring(xml_data) # 解析XML字符串for book in root.findall('book'): title = book.find('title').text author = book.find('author').text</code>

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

The history and evolution of C# and C are unique, and the future prospects are also different. 1.C was invented by BjarneStroustrup in 1983 to introduce object-oriented programming into the C language. Its evolution process includes multiple standardizations, such as C 11 introducing auto keywords and lambda expressions, C 20 introducing concepts and coroutines, and will focus on performance and system-level programming in the future. 2.C# was released by Microsoft in 2000. Combining the advantages of C and Java, its evolution focuses on simplicity and productivity. For example, C#2.0 introduced generics and C#5.0 introduced asynchronous programming, which will focus on developers' productivity and cloud computing in the future.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

Golang is better than Python in terms of performance and scalability. 1) Golang's compilation-type characteristics and efficient concurrency model make it perform well in high concurrency scenarios. 2) Python, as an interpreted language, executes slowly, but can optimize performance through tools such as Cython.

Python is easier to learn and use, while C is more powerful but complex. 1. Python syntax is concise and suitable for beginners. Dynamic typing and automatic memory management make it easy to use, but may cause runtime errors. 2.C provides low-level control and advanced features, suitable for high-performance applications, but has a high learning threshold and requires manual memory and type safety management.

Golang is more suitable for high concurrency tasks, while Python has more advantages in flexibility. 1.Golang efficiently handles concurrency through goroutine and channel. 2. Python relies on threading and asyncio, which is affected by GIL, but provides multiple concurrency methods. The choice should be based on specific needs.

There are many ways to customize a development environment, but the global Git configuration file is one that is most likely to be used for custom settings such as usernames, emails, preferred text editors, and remote branches. Here are the key things you need to know about global Git configuration files.
