什么是XML?
XML （可扩展标记语言）是一种基于文本的格式，用于存储和传输结构化数据。与侧重于显示数据的HTML不同， XML侧重于数据是什么。它使用自定义标签按层次结构描述数据，使其可供人类阅读和机器解析。
XML广泛用于Web API、配置文件、RSS源、SOAP Web服务、SVG图形以及系统之间的数据交换。它提供了一种标准化的方式来构建信息，以便不同的应用程序可以理解和处理它。

常见问题
Beautify （或pretty-print ）添加了适当的缩进、换行符和间距，使XML可读且易于导航。缩小将删除所有不必要的空白，将文件大小减少10-30%。使用Beautify进行开发和调试；使用Minify进行生产和数据传输。
Our validator checks for well-formedness: balanced opening/closing tags, proper attribute syntax, valid characters, and correct nesting. It identifies missing closing tags, unclosed attributes, and invalid XML declarations. Note: This validator checks well-formedness only, not structural validity against DTD or XSD schemas.
Yes, this formatter supports files up to 10MB. Processing happens entirely in your browser, so no data is sent to servers. Very large files may temporarily slow your browser. For files over 10MB, consider splitting them or using command-line tools like xmllint or xmlstarlet.
Completely secure. All processing happens in your browser using JavaScript — your XML never leaves your computer. No data is stored, logged, or sent to our servers. You can use this tool offline, and it works even without an internet connection after the page loads.
The tree view shows your XML structure hierarchically, making it easy to understand nesting and relationships. Each node displays the tag name, number of attributes, and child count. Click expand/collapse buttons to drill down into complex XML documents, or use the Expand/Collapse All buttons to navigate quickly.
您可以选择2个空格、4个空格、8个空格或选项卡缩进。在单击“美化”之前选择您的首选项。不同的团队有不同的标准— 2个空间是紧凑的， 4个空间是标准的，并且选项卡允许每个开发人员在其编辑器中自定义显示宽度。
