An XQuery access API is described, for providing access to XML data from a data source, using the XQuery language. A requestor can request, from a server, performance of an operation on XML data, wherein request messages and response messages conform to the Simple Object Access Protocol (SOAP). Request and response messages can be transmitted using Hypertext Transfer Protocol (HTTP) or Hypertext Transfer Protocol over Secure Socket Layer (HTTPS). The format of the request and response messages is specified in a definition of a Web service, where the definition conforms to the Web Service Description Language (WSDL).

Techniques for providing XQuery access using web services

Techniques are provided for processing a query, including receiving the query, where the query specifies certain operations to be performed, including (a) a first set of one or more operations that are to be performed on a markup language data source and (b) a second set of one or more operations that are to be performed on a second data source. Then it is determined that a first server that manages the markup language data source is capable of performing the first set of operations. A request is sent to the first server to perform the first set of operations. A response is received, where the response contains results of performing the first set of operations on the markup language data source. Finally, results are generated for the query based at least in part on the results of performing the first set of operations.
