Method Detail

getNameSpaceWithPrefix

public static String getNameSpaceWithPrefix(String prefix,
                                            OMElement elem)

Return the namespace with the given prefix, using the given element

Parameters:

prefix - the prefix looked up

elem - the source element to use

Returns:

the namespace which maps to the prefix or null

addNameSpaces

public static void addNameSpaces(XPath xpath,
                                 OMElement elem,
                                 org.apache.commons.logging.Log log)

Add the namespace declarations of a given OMElement to the namespace context of an XPath expression. Typically this method is used with an XPath expression appearing in an attribute of the given element.

Note that the default namespace is explicitly excluded and not added to the namespace context. This implies that XPath expressions appearing in Synapse configuration files follow the same rule as in XSL style sheets. Indeed, the XSLT specification defines the namespace context of an XPath expression as follows:

the set of namespace declarations are those in scope on the element which has the attribute in which the expression occurs; [...] the default namespace (as declared by xmlns) is not part of this set

Parameters:

xpath -

elem -

log -
