Interface if_ixml_node_filter_combining
Interface if_ixml_node_filter_combining
Filters allow the user to "filter out" nodes. Each filter contains a user-written function that looks at a node and determines whether or not it should be filtered out. To use a filter, you create an iterator that uses the filter. The iterator applies the filter to each node, and if the filter rejects the node, the iterator skips over the node as though it were not present in the document. Filters are easy to write, since they need not know how to navigate the structure on which they operate, and they can be reused for different kinds of iterators that operate on different data structures.
