I was recently emailed asking to have the patch for bug 55218 added in. I updated it and fixed a minor bug.
Currently if you recursively get an XML docs namespaces via SimpleXML::getDocNamespaces it will always start from the root regardless of what node you call the method from.
The patch allows you to recursively get the XML doc namespaces starting from the node you pass in.
We add in a second parameter to the SimpleXML::getDocNamespaces method called 'from_root'. This param defaults to 'true' to keep backwards compatibility. If set to 'false' then we only retrieve the namespace(s) for the node the method is called from.
Implements feature 55218
Allows you to recursively check namespaces under a child node
instead of from the root of the XML doc
