getChildAxisIterator
Iterator getChildAxisIterator(Object contextNode, String localName, String namespacePrefix, String namespaceURI) throws UnsupportedAxisException Retrieve anIterator
that returns thechild
XPath axis where the names of the children match the supplied name and optional namespace.This method must only return element nodes with the correct name.
If the namespaceURI is null, no namespace should be used. The prefix will never be null.
- Parameters:
contextNode
- the origin context nodelocalName
- the local name of the children to return, always presentnamespacePrefix
- the prefix of the namespace of the children to returnnamespaceURI
- the namespace URI of the children to return- Returns:
- an Iterator capable of traversing the named children, or null if none
- Throws:
UnsupportedAxisException
- if the child axis is not supported by this object model
-
getAttributeAxisIterator
Iterator getAttributeAxisIterator(Object contextNode, String localName, String namespacePrefix, String namespaceURI) throws UnsupportedAxisException Retrieve anIterator
that returns theattribute
XPath axis where the names of the attributes match the supplied name and optional namespace.This method must only return attribute nodes with the correct name.
If the namespaceURI is null, no namespace should be used. The prefix will never be null.
- Parameters:
contextNode
- the origin context nodelocalName
- the local name of the attributes to return, always presentnamespacePrefix
- the prefix of the namespace of the attributes to returnnamespaceURI
- the URI of the namespace of the attributes to return- Returns:
- an Iterator capable of traversing the named attributes, or null if none
- Throws:
UnsupportedAxisException
- if the attribute axis is not supported by this object model
