XQuery Basics: What is it?
MicroStrategy uses XQuery to access Web Services as a data source
XQuery is a query language designed by the W3C to extract data from XML files and format/transform the results.
XQuery is to XML as SQL is to tables in a relational database.
XQuery allows you to:
Query XML data elements of interest using XPath expressions
Transform and restructure XML data
Select information based on specific criteria
Search and join data from multiple documents
Perform arithmetic calculations on number and dates
Manipulate strings
