Xalan

Xalan is an open-source software tool used to transform and process XML data. Think of XML as a structured format for storing information, similar to a detailed spreadsheet. Xalan takes this data and applies a set of rules, called stylesheets, to convert it into different formats like HTML or plain text. This is useful for displaying data on websites or extracting specific information. Essentially, Xalan helps automate and simplify how XML data is reorganized and presented, making it valuable for developers working with data transformation tasks.
