Difference between XQuery and XSLT

XQuery: XQuery is the language for querying XML data. It is used to access information stored in XML format. It is used for fetching the information from a database that is to be used in Web services like SoapUI, receiving data from a database that is to be used with application integration, generating summary reports, to retrieve relevant information from XML files. XQuery was designed by W3C and it first appeared in 2007. 

 XSLT: XSLT stands for Extensible Stylesheet Language Transformation. It is a language that was designed to access tree structures. XSLT is used to transform XML data from one format to another automatically. When you apply XSLT to XML documents you will get another XML document, HTML, text, or any other document from technology. Its code is written inside the XML document. We can say that an XSLT document is similar to an XML document. 

Difference between XQuery and XSLT :

S.No.	XQuery	XSLT
1.	XQuery is program driven language.	XSLT is a document-driven language.
2.	It is primarily used for retrieving data from an XML document or XML database.	It is used to transform an XML document into another format, such as HTML or plain text.
3.	It focuses on data retrieval	It focuses on data transformation
4.	It has FLWOR expressions	It has template rules
5.	It is used for complex data retrieval	It is used for simple data transformation
6.	It has a more compact syntax	It has a more verbose syntax
7.	It is not written in XML.	It is written in XML.
9.	It is declarative.	It is functional.
10.	It is used only for simple transformations.	It is a language that was designed to access tree structures.
11.	It is not used to retrieve results in a tree structure.	It is used to retrieve results in a tree structure.
12.	It is shorter, faster, and more elegant for huge data jobs.	It may be difficult to maintain unless you carefully designed your stylesheet.
13.	It is designed for retrieving and interpreting information according to the specification.	It is mainly designed for transforming XML documents.
14.	The result of a query is always an XML document	The result of a transformation is an XML, HTML, or plain text document
