Write, validate, and process XML in a cloud workspace.
Start coding free →XML (eXtensible Markup Language) is a text-based format for encoding data in a structure that is both human-readable and machine-readable. It organizes data using nested elements and attributes, and is widely used for web services, configuration, document formatting, and data exchange. RunCode workspaces come with XML tooling for Python, Java, and other languages, ready in under a minute.
Open a XML workspace →XML documents use elements enclosed in tags and attributes as name-value pairs on those tags. Elements can be nested to build hierarchical data structures, and the format is plain text that works across platforms and languages. XML also serves as the basis for other formats including HTML, SVG, RSS, and XHTML, and is commonly used for data exchange in web services and APIs.
On RunCode, you can validate XML files with xmllint in the terminal, or process them in code using language libraries. Python's xml.etree.ElementTree and lxml libraries let you parse elements and extract data. Java and C# workspaces include their own XML libraries as part of the standard SDK. Pick a language, open a workspace, and the tools are there.
