XPathRouter

public XPathRouter(java.lang.String expression,
                   java.util.Map<java.lang.String,java.lang.String> namespaces)

Create a router that uses an XPath expression. The expression may contain zero or more namespace prefixes.

Parameters:

expression - the XPath expression as a String

namespaces - map of namespaces with prefixes as the map keys

XPathRouter

public XPathRouter(java.lang.String expression,
                   java.lang.String prefix,
                   java.lang.String namespace)

Create a router uses an XPath expression with one namespace. For example, expression='/ns1:one/@type' prefix='ns1' namespace='www.example.org'

Parameters:

expression - the XPath expression as a String

prefix - namespace prefix

namespace - namespace uri

XPathRouter

public XPathRouter(java.lang.String expression)
