XPATH is a Web standard for navigating in XML documents. XPATH location paths are used to extract information from the structure of an XML document, such as the author or the page number. This information is then used for XML indexing.
An XPATH location path comprises a base path and a value path.
· The base path describes a node set in the XML document.
· The value path describes the values that you want to determine from this node set.
The XPATH location path /mediadescription/header/@mediatype determines the value of the attribute mediatype of the XML tag <h eader> as an index value.
The XPATH location path //author/name/text() determines the name of the author from the XML document.
The XML indexing function of the MaxDB WebDAV Service currently supports a subset of the accepted XPATH standard.
