# XQuery — Data Scientist

As a Data Scientist, XQuery isn't about replacing SQL or Python for *most* data analysis. It’s a niche but powerful skill when dealing with semi-structured data – think XML and JSON documents stored in databases like MarkLogic or BaseX. You might encounter this when integrating with legacy systems that heavily use XML for configuration or data exchange, or when working with content management systems where data isn't neatly tabular. Typical tasks involve extracting specific information from these complex document structures; for example, pulling product details (name, price, features) from a large catalog of XML product descriptions, or parsing log files stored as JSON.
