XML::Compile::Iterator - reduce view on a node tree
It would have been nice to be able to use XML::LibXML::Iterator, but on
the moment of this writing, that module is not maintained. Besides,
this implementation of the iterator is more specific for our purpose.
The main user for this object currently is XML::Compile::Translate.
$obj->descend( [$node, [$path, [$filter]]] )
The $node is a child of the node handled by the iterator where this
method is called upon. Without explicit $node, the current node is
used. Returned is a new XML::Compile::Iterator object. The new
iterator will use the same $filter as the parent iterator by
default. The internal administered path with be extended with the
XML::Compile::Iterator->new($node, $path, $filter,)
The $node is a XML::LibXML::Node object, of which the direct
children are inspected.
The $filter a CODE reference which is called for each child node.
The only parameter is the parent $node, and then it must return
either true or false. In case of true, the node is selected. The
FILTERS is applied to all children of the $node once, when the
first child is requested by the program.
Returns the CODE reference which is used to select the nodes.
Returns the XML::LibXML::Node node of which the children are walked
The path represents the location where the node is, like a symbolic
link, how you got there.
Returns the child nodes which fulfil the filter requirements. In
LIST context as list, in SCALAR context as reference to an ARRAY.
Returns the current child node.
Returns the first child node. Does not change the current
Returns the last child node which fulfills the requirements. Does
not change the current position.
Returns the next child when available, otherwise "undef".
Returns the number of childnodes which fulfill the restriction.
Returns the previous child when available, otherwise "undef".
