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>
