XML Formatting Tool is a tool used to beautify XML strings. It can format XML strings by adding spaces and line breaks, making it easier to read.

Features:

1. Paste or input XML data that is difficult to read into the tool.

2. The tool will automatically detect the input XML data and format it.

3. The formatted XML data will be displayed in the output area of the tool.

Use cases:

1. API development and testing: When developing or testing APIs, developers often need to view the returned XML data. Using the XML Formatting Tool can convert difficult-to-read XML data into an easy-to-read format, making it easy to quickly check the data structure and content.

2. Data analysis: Data analysts need to process and analyze various XML data. Using this tool, they can easily format XML data, thereby better understanding the data structure and content.

3. XML data review: During code review, reviewers can use the XML Formatting Tool to format XML data for easier viewing and understanding of the data structure.

The implementation of the XML Formatting Tool depends on the following files:

1. xml-prettify.ts: This file is the main implementation file of the XML Formatting Tool. It uses the xml-formatter library to format the input XML data and uses the transformTool function in the @he3-kit/utils library to convert it into a usable tool.

2. utils.ts: This file defines the minifyOptions object used by the XML Formatting Tool, which contains some options for compressing the input XML data before formatting.

When using the XML Formatting Tool, users only need to paste or input the XML data that needs to be formatted into the tool, and the tool will automatically format it and display the formatted data in the output area. Users can copy the data in the output area to the clipboard for use in other applications.
