How to parse JSON in Golang?
Article Introduction：Parsing JSON is implemented in Go language through encoding/json library. Common methods include: 1. Parsing JSON strings to structures, using json.Unmarshal and defining structure field tags; 2. Parking unknown structures using map[string]interface{}; 3. Defining nested structures or nested maps when processing nested JSON; 4. Parsing JSON from HTTP requests uses json.NewDecoder(r.Body).Decode(&v), which is suitable for web development scenarios.

In Vue.js, how to implement string to object?
Article Introduction：In Vue.js, implementing string-to-object conversion requires the JavaScript JSON.parse() method. However, JSON.parse() is sensitive to invalid JSON strings and can be handled gracefully by: Catching JSON parsing errors using the try...catch block. Handle errors in catch block, provide friendly error prompts or use default values. For more complex scenarios, consider using a more powerful JSON parsing library that supports schema verification. Test string input well, write clear error handling logic, and consider using a stronger JSON parsing library to improve code stability and maintainability

How to parse strings in PHP?
Article Introduction：Parsing strings is a very common and important operation in PHP, and you will use it whether you are processing user input, reading file content, or interacting with a database. Today we will explore in-depth various methods and techniques for parsing strings in PHP. In PHP, there are many ways to parse strings, from simple string functions to regular expressions to more complex parsing libraries, each with its own unique application scenarios and advantages and disadvantages. Let’s start from the most basic and gradually deepen into more complex analytical techniques. First, let's take a look at the most commonly used string functions in PHP. These functions are simple and easy to use and are suitable for handling basic string operations. For example, the exploit() function can split the string into numbers according to the specified separator.

XML to PDF, what are the useful tools on your phone?
Article Introduction：There is currently no one-click method to handle XML to PDF directly and perfectly on mobile phones. The reason is that the XML structure is complex and requires powerful parsing and typography capabilities. XML to PDF is essentially data conversion and typography. The process includes: 1. parsing XML structure and content; 2. processing and formatting data; 3. Calling the PDF generation library to generate PDF files. For complex XML files, it is recommended to use cloud conversion services or write your own code for conversion.

Optimize AJAX data transmission: Correctly receive nested arrays and complex parameters in PHP
Article Introduction：This article explores how to correctly receive and parse nested arrays on the PHP backend when sending complex data structures using AJAX. In response to the problem of PHP receiving as strings in JavaScript, two solutions are provided: one is to use PHP's parse_str function for backend parsing; the other is to use JSON format for data transmission, serialization is performed on the front end through JSON.stringify, and parsing it on the backend using json_decode to achieve more robust and standardized data exchange.

How to modify CDATA content in XML
Article Introduction：The CDATA area in XML provides a mechanism to safely handle special characters without parsing. When modifying CDATA content, you need to use an XML parser, such as the xml.etree.ElementTree library in Python: parse XML strings and look for elements containing CDATA. Get the text content of the CDATA. Modify the text content. Reset the CDATA content. Write the modified XML to a file or output as a string.

Title: The correct way for Python regular expressions to handle nested brackets
Article Introduction：This article aims to introduce how to use Python's regex library to effectively process strings containing nested brackets through recursive pattern matching. We will show how to match and remove content in nested brackets while excluding specific situations, such as retaining that part of the content when the first word in brackets is a specific keyword. This is of great significance for parsing complex text such as Wikipedia file dumps.

How to use C with JSON?
Article Introduction：C To handle JSON, you need to select the appropriate library and master the basic operations. 1. It is recommended to use nlohmann/json, which is suitable for modern C and has concise syntax; RapidJSON performance is better; JsonCpp is suitable for old projects. 2. Basic operations include constructing JSON objects, parsing strings and type-safe conversion, such as using j["key"] to assign values, json::parse() to parse, and .dump() to strings. 3. In actual applications, you can define to_json/from_json to implement structure serialization. 4. Notes: Ensure that version C supports, add error handling, use indented .dump(4) to view the structure during debugging, and avoid
