Information storage is only useful if the information can be easily retrieved. Usually, information is retrieved from a relational database by sending commands (for example, Structured Query Language [SQL]) to the server. An XML document can be considered a facility for data storage, and therefore, can also be considered a rudimentary database. Just as SQL is the standard language for relational databases, the XML community has developed their own set of standards for retrieving information from an XML document. XPath is a standard that defines the syntax for addressing and fetching parts of an XML document.
Note
XPath and many other XML-related standards can be found on the web at http://www.w3.org.
