Pattern Syntax |
The XPath pattern syntax is described formally in the XPath specification. Here we’re going to look at the syntax in abstract, but less formal terms: |
• An XPath pattern is a ‘location path’, a location path is absolute if it begins with a slash (“/”) and relative otherwise • A relative location path consists of a series of steps, separated by slashes • A step is an axis specifier, a node test, and a predicate |
The formal syntax is made more complicated by the fact that it must describe both the abbreviated and unabbreviated syntaxes |
