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.
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 PATH.
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 through.
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 position.
Returns the last child node which fulfills the requirements. Does not change the current position.
Returns the next child when available,
Returns the number of childnodes which fulfill the restriction.
Returns the previous child when available,
Returns the textContent of the currentChild() node, or undef.
Returns the local name of the currentChild(), or the empty string.
Returns the type of the currentChild(), or the empty string.
Returns the local name of the node(), or the empty string.
Returns true if the current node has
Returns the type of the node(), or the empty string.
Returns the textContent of the node(), or undef.
