> Add methods to OMElement that allow calculating the namespace context of an

>
> Key: AXIOM-388
> URL: https://issues.apache.org/jira/browse/AXIOM-388
> Project: Axiom
> Issue Type: New Feature
> Components: API
> Reporter: Andreas Veithen
> Assignee: Andreas Veithen
> Fix For: 1.2.13
>
>
> There are a couple of things that the average Java developer is unable to
> code correctly. One of these things is calculating the namespace context of
> an element in an XML document.
> Examples:
> (1) The following change in Axis2 attempts to resolve an issue where the
> databinding fails to resolve a QName value if the prefix is declared on the
> SOAP envelope:
> http://svn.apache.org/viewvc?view=revision&revision=398161
> Strictly speaking this change is incorrect because it only takes into account
> namespaces declared on the soap:Envelope, but not on the soap:Body.
> (2) The following change in Synapse adds code to compile an XPath expression
> retrieved from an XML configuration document:
> http://svn.apache.org/viewvc/synapse/trunk/java/modules/core/src/main/java/org/apache/synapse/mediators/Value.java?view=diff&r1=1080144&r2=1080145&pathrev=1080145
> To build the namespace context for the XPath expression, the code uses
> OMElement#getAllDeclaredNamespaces() on the element that has the attribute
> the XPath expression is extracted from. That is incorrect because namespaces
> relevant for the interpretation of the XPath expression may also be declared
> on ancestors of this element.
> (3) RAMPART-40 introduces code that attempts to build a namespace context by
> scanning the entire document tree for namespace declarations (!).
> To avoid these issues and to make life easier for developers, Axiom should
> define high level methods that allow to calculate the namespace context of a
> given element. There should be actually two methods:
> * One that returns an iterator over all namespace declarations in scope. This
> method could be used e.g. to initialize the namespace context of an XPath
> expression.
> * One that returns a NamespaceContext object that can be used with other XML
> APIs that support this interface.
